Hi Dear GrADS users

How can I create TTF format of output maps instead of png and gif?
I am using GrADS in LINUX OS(ubuntu 10.4) and 2.0.a9 oga version
of GrADS.

Message-ID: <CAPFxStjW0zonvY-jjLBn7S=f2Nmj=wXvJhFYdHBBAP-H4sG=pA@mail.gmail.com>

Dear all,

I would like to have your confirmation for this expression in grads:

Exponential: 'exp (expression)' is it true?

And how if I want to make something like:

(a+b)*(a+b) = (a+b)^2 is that true?
(a+b)*(a+b)*(a+b) = (a+b)^3 is that true?


Thank you,

Regards,

Hi all,

You can also use CDO if you have Windows. In addition to what Saeed had
said, you can also :

cdo -r mergetime ifile1 ifile2 ifile3 ofile

depending on what you need.

Regards,

Serge

Dear all,

I found it, Thank you anyway.
For power, just 'pow(exp,yourpower)' where exp your expression and yourpower
the power you want.
So it becomes:
(a+b)*(a+b)*(a+b) = pow ((a+b),3)

Regards,

Serge

Message-ID: <06B0A85218E0A34EBBFFF4435CA4BAA403C8F691F3@sawsptahub01.saws.local>

I have tried to avoid the page (X,Y) boundary markings by using the attached script but the marks always appears. The IF STATEMENT  does not appear to do the trick; how do I make sure that the marks at the boundaries do not appear but the interior marks appear?
For instance,

1)      if('bcx'!='xx1'| 'bcx'!='xx2' | 'bcy'!='yy1' | 'bcy'!='yy2')
'draw mark 4 'bcx' 'bcy' .1'
else
'draw mark 0 'bcx' 'bcy' .1'
Endif
RESULT IN MARKINGS ANYWAY,




2)if('bcx'='xx1'| 'bcx'='xx2' | 'bcy'='yy1' | 'bcy'='yy2')
'draw mark 0 'bcx' 'bcy' .1'
else
'draw mark 4 'bcx' 'bcy' .1'
Endif
STILL RESULT IN THE MARKINGS, AND

 3) if('bcx'>'xx1'| 'bcx'<'xx2' | 'bcy'>'yy1' | 'bcy'<'yy2')
'draw mark 4 'bcx' 'bcy' .1'
Endif

MARKINGS STILL AT THE BOUNDARIES.

NOTE: For testing choose BCX=XX1,BCY=YY1 or BCX=XX1,BCY=YY2 or BCX=XX2, BCY=YY1, or BCX=XX2, BCY=YY2.

there is a conceputal error, let's understand the meaning of:

  if('bcx'!='xx1' ...

this logaical is always false, because 'bcx' is a string, 'xx1' is a
string and they are different


in your script appears:

  'draw mark 4 'bcx' 'bcy' .1'

then it is clear that bcx is a scalar (it has a value)
...

correct the logical expr in this way:

  if(bcx!=xx1 ...

hoping it helps
bye bye

Subject: [gradsusr] correlation map
Message-ID: <CAOXKaKD3cZXGvrLaPtg_PAp_PDaALUW+xtDW+MN8Ex_NsJ5Xyg@mail.gmail.com>

Hi

I have 20 year composite in which i have two variables (meridional and zonal
wind speeds). I'm using the NCEP/NCAR reanalysis data from 1989 to nov2008.
I need a (spatial) map of correlation coefficients for that period.

I've explored the functions tcorr and scorr, but none of them is suitable
for that. The tcorr function requires that the first variable is only a
function of time, which is not in my case.

Thanks is advance

Sushant

Message-ID: <CA+-goCcnjXsu7GH0kguCr-LDADefb-uxzkeQXeHy7dWDzovp3w@mail.gmail.com>

Hi all,

I was wondering if using fwrite to write a binary file if it is possible to
specify the format to avoid having it in stream. For example, the data be
written at a format like 8e10.3 to have a formatted file. How to do it?

thanks

Subject: [gradsusr] if... else..... endif syntax error in GRADS
Message-ID: <CAPFxStizChjZay3FmxZouRQQSi5cMuNzEVHqb5wxoY5_cVuGXg@mail.gmail.com>

Dear all,

My file contains 2 variables a and b. I have the following condition:

if a>b => c=b
if a<b => c=a

so: d=c/b

in my .gs file, I tried:

'!if (a> b)'
'c= b'
'!else'
'c= a'
'!endif'
'define d=c/b'

but it gives syntax error.

Then I tried to define the c like:

'!if (a> b)'
'define c= b'
'!else'
'define c= a'
'!endif'
'define d=c/b'

Again, syntax error.

ERROR:
sh: -c: line 1: syntax error: unexpected end of file
sh: -c: line 0: syntax error near unexpected token `else'
sh: -c: line 0: `else'
sh: endif: command not found


Thank you in advance,


Best regards,

Dear GRads Users,

I've scoured the mailing lists and been back and forward with ECWMF. I've two sample files from them (ECWMF GRIB v1) which I simply can not get translated properly. If anyone can offer some assistance I'd greatly appreciate it before I go and do a lot of installing of ECWMF software that may not be needed. ECWMF does not have their GRIB2 versions of this data.

I've attached both samples - they are supposed to be weekly anomalies of 2m temperature and precipitation.

Many thanks.

A pilot project in Nicaragua on heavy rainfall and landslide early 
warning in near real time:
http://georiesgos-ca.ineter.gob.ni/lluvia/nesdis/gif/index.html

You have to place the cursor over the map to see a movie. The single GIF 
frames are made with Grads from the NESDIS Hydroestimator data and are 
then put together with ImageMagick to generate the animation. On the 
left you can select a region or country in the Central America-Caribbean 
area.

The system is capable to generate alert messages by email when strong 
rain occurs over a landslide prone area, e.g. volcanoes in Central America.

Subject: [gradsusr] Isentropic variables and ctl files
Message-ID: <CAK55UEfqP_CyoSQaf6rNjf-fsc1Jih7XXcn7ogu9PEKapT+EJQ@mail.gmail.com>

Hello, everyone.

I'm working with Bob Hart's isentropic field script. One of my goals is to
process guidance for several isentropic levels, store the variables in a
file (NetCDF is the method of choice, at present), then retrieve each of the
isentropic levels by way of the "set lev" command with each of the
isentropic surfaces listed in the .ctl file under "zdef 9 levels" as  "290
292 294 296 298 300 302 304 306". Is there a method or process to execute
the isentropic script several times for several isentropic surfaces and
store the output in a single variable? For testing I'm working with NAM
data.

Many thanks,

Kevin Huyck.

Are you keeping track of GDS servers? Or other "non-graphic" sites that
still have grads as a backend? For example, our "download tool" sites, e.g.,

Message-ID: <CAHCbKuNazS2GLtGGK+Lpw4-tgnRrRK7rc3_ov888qaPr44Mz4Q@mail.gmail.com>

Hello.
I am using GrADS version 2.0.a7.oga.3.  I have a long paleoclimate
timeseries going from 3800 years before present to 12300 years before
present.  When I plot a section of this time series (i.e. 3800 to 7000) the
x-axis labels appear normal (i.e. 3000 4000 5000 ...).  However, when I
attempt to plot the entire timeseries the x-axis labels disappear except for
a single label appearing at 4000.  Attached are screen shots showing the
situation.  Any suggestions on how to remedy this would be greatly
appreciated.

Thanks!

Best,
Max

Message-ID: <20110708150313.y5vi2zjzwc4gkgwc@cubmail.cc.columbia.edu>

Hi Gradusers,
I am trying to get a temporal correlation of two data sets that also  
vary in x and y. Just to give you some context, I am comparing model  
data to observed data over a 52 year span. I wrote a script that  
calculates point by point temporal correlation by use of the tcorr  
function, but it is unusable for me as it is very inefficent! Was  
wondering if anyone had a correlation script/ suggestions for me?
here is the script:

***function to plot a temporal correlation with a spatial loop
function correlation(arg)

startx=subwrd(arg,1)
endx=subwrd(arg,2)
starty=subwrd(arg,3)
endy=subwrd(arg,4)
startt=subwrd(arg,5)
endt=subwrd(arg,6)

say 'longitude = ' startx ' to ' endx
say 'latitude = ' starty ' to ' endy
say 'years = ' startt ' to ' endt

x=startx
while (x<= endx)
'set x ' x
y=starty
while (y <= endy)
'set y ' y
'set t ' startt
'd tcorr(prcp.1,prcp.2,t=' startt ',t=' endt ')'
y=y+1
endwhile
x=x+1
endwhile
exit

Gabriel,

Not sure if this will do what you want (may be more than you need), but 
here's an email posted to the Listserv by Mary-Jo Nath:
http://gradsusr.org/pipermail/gradsusr/2006-August/003552.html

Hope this helps,
Chuck

Hi Max,
Try this: set xrange t-first t-end
             set xlabs numbers that you want put in x axis(set xlabs 1 2 3 4
5 6 7  ...)

Dear all,

I am totally new with Grads and not very good at informatics. I have a bunch
of OMI SO2 images from the Aura satellite and I don?t achieve to write the
right descriptor file to get to open the images with grads. Has anyone an
example of descriptor file for OMI or some ideas to help me to overcome this
problem? I would be very greatful.

Best regards to you all,

Subject: [gradsusr] Wrf output in GrADS
Message-ID: <fcc6d2e76c24.4e18668f@fsu.edu>

Hey Everyone,

A while back I received some help with displaying WRF output in GrADS using ARWPost.  Thanks!  Now, I have a question about some of the fields.  When I display some fields, the look normal and as expected. But, others look odd.  I have attached an image of my 'w' field at 500 hPa.  Some other fields, such as the boundary layer height, also share this pattern.  Other fields, such as the 'u' and 'v' winds, look fine.  I was wondering if this looks like an error somewhere in my ARWPost run or an error in my WRF run?  Thanks an advance for any help!

You could try to comment "options byteswapped" in the ctl file.

If Yaqiang's idea doesn't work, I would try re-running ARWpost with fewer
variables.  I doubt you really need all of those variables, and if your .dat
file is too large, there may be a problem with how it displays data.  Also,
it appears your XDEF and YDEF lines could be simplified by putting
XDEF 210 LINEAR 0.0217
or something like that, since all of your levels appear to be equally
spaced.

Thanks Saeed.
Unfortunately, it seems the set xlabs and set vrange2 commands do not
operate on the x-axis when it represents time. Perhaps I need to edit how
time is defined in the .cdl file.

Best,

Introducing InstantWeatherMaps.com, a new weather model website. The site
has a lag (from when the raw data appears on the NOMADS server) of 10-30
seconds, compared to around 90 seconds for the closest other free site (the
new beta NCEP site). I offer over 150 variables, including Kuchera-method
snowfall (otherwise only found on Earl Barker's site, which has a lag of
around 30-90 minutes). Nearly a half-million GFS model maps are on my server
at any given time. I would appreciate any suggestions as to future
enhancements I could make to my site.

Consider using anti-aliasing fonts and lines, e.g.,

     http://portal.nccs.nasa.gov/cgi-yotc/fp_wx.cgi

This is obtained by replacing printim with gxyat. Make sure to read the
documentation for a trick to reduce the size of the image files (pipe to
pngquant) , something that would be important for you with 1/2 million
plots. Notice that you will need the opengrads bundle for this,


http://opengrads.org/wiki/index.php?title=Installing_the_OpenGrADS_Bundle

Type

ga-> gxyat

for a manual page.

Thanks for the suggestion. I ran tests of gxyat vs printim and found that
gxyat outputs roughly 4 images per second, and printim outputs roughly 20
images per second (when set to GIF mode, which about 65% faster than PNG at
the expense of a roughly 15% larger file size). I will keep using printim
for the forseeable future, since output speed is paramount to my site's
operation. I do have another question, though, which I will ask in a
separate message.

Subject: [gradsusr] NOMADS download speeds
Message-ID: <CAJv4EQqs3FZN=DqHTgh_R+ivDHTwv9NfcipU_TSszgO=48LVpA@mail.gmail.com>

Is there any way to speed up downloads from the NOMADS server (
http://nomads.ncep.noaa.gov/cgi-bin/filter_gfs_hd.pl)? I currently run a
site that spends around 6-8 seconds per forecast hour generating maps.
Having said that, it is quite frustrating to see download times for 1 MB of
GRIB data exceed 10 seconds at times. I currently use 4 wget sessions in
parallel to handle the downloading, and I only sleep for 2 seconds instead
of 10 when polling the NOMADS server to check when the next file is
available, so as you can see I am very speed-oriented. Is there any way to
download faster, or is partial-downloading (downloading part of the GRIB
file, generating the relevant maps for the first part while the rest
downloads, then generating the maps for the rest) the fastest way of doing
this?

Subject: [gradsusr] Computation of thermodynamic Indices
Message-ID: <BLU152-w42402221CC2A51228FAB7F8A450@phx.gbl>


Dear All, 
This problem is not particularly pertaining to Grads but  I am still putting it across in anticipation of a possible help.


It goes like this, I want to compute all the Standard Indices  
( like Showalter, K, SWEAT, CAPE, CINE  etc)
from the Rs data of a station. 


I am able to compute only LCL and then the moist adiabat (using the conservation of MOIST static energy) 
and I have computed the LCL from the RS data and then constructed the moist adiabat of the parcel till 200hPa. Part of the output of moist adiabat looks like this, 

(I)
INPUT LCL

 P T Z
 871.0 294.6 312.0
 MOIST ADIABAT
 P Z T Q NO OF ITRN
 871.0 312.0 294.6 .1952E-01 .3476E+06 0
 870.0 322.0 294.5 .1950E-01 .3476E+06 39
 869.0 332.1 294.5 .1947E-01 .3476E+06 39
 868.0 342.1 294.4 .1945E-01 .3476E+06 40
 867.0 352.2 294.4 .1942E-01 .3476E+06 39
 866.0 362.2 294.4 .1940E-01 .3476E+06 39
 865.0 372.3 294.3 .1938E-01 .3476E+06 40
 864.0 382.4 294.3 .1935E-01 .3476E+06 39

"MOIST.DAT" 676 lines, 44480 characters

(II)
My RS data of a station is at an interval of 50hPa and looks like this (Ht, TT, Td, WS, WD at different levels)


1981 03 10 00 2 1026 20.6 16.8 155 02 1520 18.6 11.2 201 04 ^M
1981 03 10 00 3 2038 15.6 8.2 195 03 2584 12.4 3.8 079 02 
 3159 8.4 -5.3 105 04 3768 4.8 044 03 




Kindly help me reg the computation of CAPE and CINE after I construct the MOIST adiabat for a station.

Dear forum members,

I met a specific problem with GrADS plotting shape files.
The first time with Linux applications I met a problem when
all graphical KDE system is shut-down and rebooted,
like MS Window!
All and any do not saved results
of any applications in the running session are lost...
Please be careful if you will try to reproduce this behavior!

GrADS version is
Config: v2.0.a9 little-endian readline printim grib2 netcdf hdf4-sds
hdf5 opendap-grids,stn geotiff shapefile,
Linux workstations runs openSUSE 10.3 (X86-64),
kernel version 2.6.22.19-0.4-default

After downloading some shape files from the
http://www.diva-gis.org/Data,
namely "countries" from the Global level data
and South Korea administrative boundaries
from the Country level data,
I permanently have this problem if
run next sequence of commands.
I tested it with the Word Ocean Atlas 2005 netcdf
files:

d something
draw shp countries
draw shp KOR_adm0

... and nothing more on the screen,
the new graphical session starts.

As I believe that all shape files are just data,
there must be some problem with memory
operations in the GrADS, I guess.

Individual shape files are plotted without problem,
including both mentioned, as just shapes or as filled polygons.

Does somebody had similar problem and do it is possible
to avoid such surprises with these or other shape files?

Sincerely yours,
Sergey Varlamov

Dear Nagaraju,

Thank you for your answer but I've already found it. Below is the script:

if (a> b)
'define c= b'
else
'define c= a'
endif
'define d=c/b'

Anyway, the if expression in grads is not accompanied by then.

Regards,

Serge

Joey,

       My impression of the nomads server is that it is very fast.  
However, I have a very fast link to the internet and
the site is only 10 miles away.

      You are using the GFS which has 0.5 degree resolution (260K 
points) and you are using the filter program
which can create a regional subset.   If you are asking for a 5x5 grid, 
then your download speeds will be
slow.  After all you have to process 10K points for every point sent to 
you. 

     Another possibility is that you may have run afoul of some 
fair-usage filter.   Every site needs some protection
against denial-of-service attacks and poorly programmed web scripts.  
Anyways the nomads help desk is a more
appropriate source of information than the GrADS user forum.

Dear Sir
I installed GDS in MAC OS X  10.6.3.(intell duo)  The grads version is v2.0.a9.javaa version is 1.6.0_17.
The GDS work properly with the ctl file/binary.But when I access the station data, the error message come listed below. I found probably the same problem in the grads previous mailing list in http://gradsusr.org/pipermail/gradsusr/2008-September/007531.html.Unfortunately, there is not enough information on it. I attach three logs files (console.out, gds.log, tomcat.xxxx.log) for more detailed information.Could you tell me how to solve this problem?

Start by reading the documentation:

       http://grads.iges.org/grads/gadoc/SDFdescriptorfile.html

You likely need to create a DDF and use xdfopen.

I have two 2D model grids that have the same horizontal grid spacing and the
same domain width (so the X-coordinate is the same between the two) and the
same domain height, but different numbers of levels in the vertical.  I wish
to compare the values of some variables such as vertical motion between the
two model grids.  How do I do that?

Are the levels really different, or one file is a subset of the other? Say,
one has fewer mandatory levels. If the latter, use lats4d or write your own
simple script to subset the larger file to make it appear as the first. If
the levels are really different, you will need to perform a remapping from
one vertical grid to another. This remap algorithm can vary from a simple
linear interpolation in log-p to a conservative scheme that preserves
monotonicity, all depends on your application. I usually perform this
remapping outside grads.

No, they're truly different in the sense that probably none of the levels
perfectly match up.  What algorithms do you know of?

Dear all,

I'm using grads 2.0.a9.oga.1 installed in the c:\ drive of  Windows XP. I
wrote a batch script(.bat) to generate graphical outputs from
http://nomads.ncep.noaa.gov:9090.
The script works if it is   placed in any folder in the C:\ drive but fails
when it is  run from a pendrive, external drive , d:\ drive etc. Among the
content of the script is:  grads -blc "run script.gs"

The following messages were displayed on the execution of the script from an

Jeff and Yaqiang,

Thanks for the ideas.  Unfortunately, I still haven't found a solution.  I have figured out a little more about the problem, I think.  It appears that it is the "standard" variables that look odd.  If I display the umet and vmet diagnostic variables, they look great.  But, if I display the standard U and V variables, they look just like W did.  

As you suspected Jeff, I don't need many variables, actually only the U,V, and W wind components.  But, even when just running ARWpost with the 'basic' fields option the variables look crazy.  Any more ideas would be greatly appreciated!

Thanks,
Nick

The netCDF data output from WRF are not follow COARDS or CF
conventions, so the data can't be read directly by many popular
meteorological softwares, including GrADS (I mean with sdfopen
method). I don't understand why WRF group made their data different. I
have no experience on ARWpost tool, but I know something of the netCDF
data format used in WRF, which is defined as 'WRF_OUT' conventions in
MeteoInfo software. So you can try to graph the data using MeteoInfo
temporally before you find a better sollution of it. You could only
use MeteoInfo in Windows system for netCDF data, although it could be
used in Linux for other data formats under the support of mono.

Nick,
Try viewing the raw netCDF output using ncview or use ncks to output the
actual coordinate values of some of the variables so that you can see them.
If the data looks bad when viewing the raw netCDF output, then something
went wrong in your model and ARWpost has nothing to do with it.  If it looks
clean, then it's something with ARWpost.  Let me know what you find out.

First, make sure you have a version of GrADS that supports reading HDF-EOS5 grid files (2.0.a7 or higher).
Below is a sample GrADS control (.ctl) file that will let you read an OMI SO2 level-3 gridded HDF-EOS5 data file:

DSET  OMI-Aura_L3-OMSO2e_2004m1001_v003-2011m0526t144250.he5

ENDVARS


Note the group paths to the data field variables must be specified in full, and any spaces converted to tilda (~) characters.

You can rename the OMSO2e data files by removing the production date/time from the version (stuff after v003), then you would have 
a file name like OMI-Aura_L3-OMSO2e_2004m1001_v003.he5. With this you could modify the DSET (and add OPTIONS) to the .ctl file

DSET  ^OMI-Aura_L3-OMSO2e_%ym%m%d_v003.he5
OPTIONS template

and then you could read in multiple files for a range of dates (remember to also adjust the TDEF range).

Hi everybody,
I would be grateful to somebody who can clarify the foll point.
I want to check the rainfall output from a particular WRF simulation. Is the
total rain a sum of rainc and rainnc??. if cumulus scheme is not activated
then rainc = 0, so total rain = rainnc.

thanks in advance

Warm regards,
Roopa

what's the name of the precipitation variable you are using?  RAINC is
convective scheme precip, RAINNC is microphysical.  If you sum them, then
you get total precip.

See http://cookbooks.opengrads.org/index.php?title=Recipe-013:_Gridding_and_Plotting_Station_Data
and http://www.iges.org/grads/gadoc/aboutstationdata.html
and http://www.iges.org/grads/gadoc/usingstationdata.html

I see that your precipitation data sometimes is followed by a comma and another value. You should clean that up first.

For more insight from GrADS users, Google using the phrase 'station data site:gradsusr.org'

Message-ID: <979990096.135125.1310756439268.JavaMail.root@mailhub017.itcs.purdue.edu>

Hi, 

I'm trying to plot a timeseries of wind barbs of both WRF output and collected observations.  I'd like to plot WRF wind barbs first, then overlay observation data as wind barbs also.  However, my wrf data is gridded data and my observation data is reading into GrADS based on the 'x' coordinate.  Therefore for the obs data, I must use "set x " to pick out a time range.

Thanks,

Dear Grads Community,
  I'm new to GRADs, and I'm trying to get it started up on a Mac. I'm trying
to work through the tutorial to start with. I can either not properly
download the practice files, or I can't properly get my version of GRADs to
locate these files. Any suggestions?
Thanks so much,
-Alex

If you mean the model.ctl, model.gmp, model.grb files, I usually put them in their own directory, like ~/grads/tutorial, chdir to that directory, and THEN start up grads.  Then you need to make sure that (1) you can find the grads executable and (2) you can find the other grads files, like the fonts and maps.

For #1, you can either (a) add the location of the grads executable to your $PATH variable, (b) set up an alias with the full path of your executable or (c) just type in the whole path of the executable (ugh).  In my case, I have it in my PATH, which includes /Users/clynnes/bin:

~/grads/tutorial>which grads
/Users/clynnes/bin/grads

For #2, make sure you have your GADDIR environment variable set to the directory where you installed the fonts and maps. On my Mac, for instance:

~/grads/tutorial>echo $GADDIR
/Users/clynnes/etc/grads
~/grads/tutorial>ls $GADDIR
dat		font3.dat	lomap.dat	nmap.dat
font0.dat	font4.dat	lowres		stroke.dat
font1.dat	font5.dat	mres		udunits.dat
font2.dat	hires		newmap		worldmap
~/grads/tutorial>

If you have installed the opengrads bundle, the sample file is included. Try
this:

ga-> @ open $GADSET/model

Message-ID: <EF993BF88A0DA241AA5B306C9D22DDF753FF3FDF@it-kodiak.sooner.net.ou.edu>

Hello Grads community,

I can see from the tutorial that one can open several different case files in grads(file1, file2 etc) and average the data from these files for subsequent display. Is there an advanced option that would allow me to specify the domain for each case and then average them? I was hoping to use this function to easily complete an average of 25 cases or so but relative to some specific type of event, which requires different domain centering for each case prior to averaging.

The ave() functions allows you to make averages over a (x,y,z,t,e)
hypercube. Because undef values are skipped, you can have averages over very
irregular domains, provided an appropriate mask can be derived either
through an expression or by reading it from a file.  For example, to make a
time average along satellite swaths we could do

define xmean = ave(x+0*sat.2,t=1,t=124)

where "sat" (on file "2") is some gridded (time dependent) satellite
measurement with lots of undefs.

Dear gradsusr,

Is it possible to plot a map, without using any parameters? that is simply
getting the outline of the coastlines for the region?

And possibly even draw a few dots or crosses at particular locations
according to lat/lon information?

I don't even know if I am on the right track. Can someone help me get to an
answer please? because I am not managing to follow the help on GrADS index.

I have also attached the text file with the remaining information

Dear gradsusers,

i invoke a gradsscript from bash and in case that the script can not 
open a file past to it, i want to give a return code back to the 
bashscript so that it knows, that the gradsscript could not open the file.
I have no idea how to do this. For subfunctions in grads i can use 
return but it seems not to work with the main function.
To exit early on i have to use quit it seems but with quit i can not 
give a return code.

I hope someone have a idea.

Best Regards,
Simon

If you are running GrADS in batch mode you can re-direct output as follows

grads -lbc 'run somescript.gs' 2> say.err 1>&2

In interactive mode there is no output to the screen it simply goes to the file.

Does that answer your question?

To plot a map with no parameters, first open any file with any parameters
(even the sample file will work). Then do this:

set clevs 0
set ccols 0 0
d param

where param is a valid parameter in that file.

You need to change DSET to:

DSET ^OMI-Aura_L3-OMSO2e_%y4m%m2%d2_v003.he5

and make sure the files are actually named something like:

OMI-Aura_L3-OMSO2e_2004m1001_v003.he5

What I like to do is keep the original files as downloaded from the archive, 
and then set up symbolic links with those types of names above. You can write 
a short Unix shell script to do this:

for file in OMI-Aura_L3-OMSO2e*.he5
do
  ln -s $file `echo $file | cut -c1-33`".he5"
done

I would also set TDEF to:

TDEF  3014 linear 01oct2004 1dy

and then you'll be able to read any of the files through the end of 2012, also 
the first day for OMI data is Oct. 1, 2004 (launch was July 15, 2004).

the 'draw map' command will also do it, but it won't plot any lat/lon lines
or coordinates since it won't have any actual map data to go off of (but it
will give you geo-political boundaries just fine)

Sushant and Diallo,

I found a confusing comment in the maxwind.gs and maxwind2.gs scripts 
referring to "plotting track of hurricane center" (not sure, but 
possibly left over from code copied from another script?), and changed 
the comment to "plotting location of max wind". Please find attached 
updated GrADS scripts maxwind.gs, maxwind2.gs.

Sorry for this confusion,
Chuck

Hello Arlindo,

I need to set a different domain center for each of the time periods in the ave function, like say 1 through 124 in your example. As such, the display would then become geographically irrelevant, asides from attaining a since of scale.

Hello Grads community,

I can see from the tutorial that one can open several different case files in grads(file1, file2 etc) and average the data from these files for subsequent display. Is there an advanced option that would allow me to specify the domain for each case and then average them? I was hoping to use this function to easily complete an average of 25 cases or so but relative to some specific type of event, which requires different domain centering for each case prior to averaging.


The ave() functions allows you to make averages over a (x,y,z,t,e) hypercube. Because undef values are skipped, you can have averages over very irregular domains, provided an appropriate mask can be derived either through an expression or by reading it from a file.  For example, to make a time average along satellite swaths we could do

define xmean = ave(x+0*sat.2,t=1,t=124)

where "sat" (on file "2") is some gridded (time dependent) satellite measurement with lots of undefs.

You can use HDFView to get the information first, and then to set the
information in the control file. HDFView is free avaliable at HDF
offical website.

Subject: [gradsusr] pdef file works at v1.9b4 but not  at v2.0.a9
Message-ID: <40829B0E077C1145A6DE44D39B3830A91FFD68B0C9@nerckwmb1.ad.nerc.ac.uk>

Dear All,

I have a dataset that uses a pdef file and that I can use in GrADS v1.9b4 (in both SunOS and RH executables downloaded from the GrADS website), but which results in a segmentation fault at v2.0.a9 (and, from memory, at v2.0.a8) - again in various downloads. Looks like it might be a bug in GrADS...but of course most things turn out to be user error! Any ideas?

At v2.0.a9:

-------------------------------------------------------------

Vague notion: The pdef data file is big-endian (as declared in the pdef line of the ctl file) but
I'm using a little-endian machine. I wonder if v2.0.a9 can't cope with this mix?


Cheers,
Doug

Subject: [gradsusr] set negative values to zero
Message-ID: <CABzcqstV-9hAcC4KLR7BE2tnsu4pOsOU4YK4uQE3=2K5k-JZ9Q@mail.gmail.com>

Dear GrADS users,

I am using GrADS v2.0.a9 in Linux.

I am going to set negative values to zero at each grid point in NetCDF file.
I've been trying this using "if statements" in .gs file like below,
but it didn't work.

'open .ctl file'
 if (varname < 0.)
    varname = 0.
 endif

If you have any experience in GrADS for this, please let me know.

Thanks in advance,
Eugene

Subject: [gradsusr] in netcdf file unable to display 4-D variables

Jonathan,

This sounds familiar... GrADS may not be able to display both 3D and 4D 
fields if they are in the same netCDF file (don't know why)... One thing 
to try is to extract the 4D fields into a separate netCDF file (e.g. 
using "ncks" if you have it).

Hope this helps,
Chuck

Hi,
you can do like this also.
'open {your control file}'
'set gxout fgrid'
'd {any parameter in your control file}'

It will also work

Hi John,

thanks for your answer. I know how to redirect channels on the command 
line.
But how to decide IN the script, what should go to stderr and what to 
stdout, 'say' always put the output to stdout.
So in bash i would do echo "foobar" 1>&2 to get the foobar to the 
stderr, how can i do this in GrADS? Is there a way?

Best Regards,
Simon

Sergey,

Thanks for your answer. In fact I don't think your suggestion was the answer I needed, but it did cause me to look at the documentation again, at which point I got my answer!

My data are essentially a "vector" of land points and I use the pdef to scatter these across a lat-lon grid (very like the final example on the pdef documentation page). So the "native grid" really is 67420 x 1. The problem was that in the pdef data file (WFD_0p5deg_pdefData.gra in my example below), I had values of zero for the index (or offset) variable over the sea - i.e. the locations that I didn't have data for. These would have been better set to the missing data value. At v1.9.b4, the zeroes worked fine (and I was blissfully unaware that GrADS was struggling with different offset values for GRIB and non-GRIB files). At v2.0.a9 presumably GrADS notes that I don't have a GRIB file and tests the offsets; when it finds a zero it fails (rather dramatically with a core dump!).

So the answer was to make sure that my offset is set to the missing data value where I don't have data. Which sounds (and is) pretty obvious, but had worked for years with zero instead!

I have been using this style of pdef file for years and hadn't noticed that the online documentation for pdef now has various "WARNING" and other messages documenting issues with the offset (and that pdef FILE is now deprecated in favour of pdef GENERAL).

Thanks again,
Doug

Douglas,

The zero values for the mask in pdef file look to be normal.
But reading your netcdf require to know each dimension size
"as it is" in your file. When you provide description file (ctl)
grads ignore internal netcdf information for dimension
using yours instead. Then, for the input arrays allocation
"67420 1" is OK, but the real netcdf lat-lon grid size is necessary for
correct data input before the pdef mask  application.
Please run ncdump on you file and try "nx ny" instead.
Just it must help. Or, if you are ready to rebuild an interpolation
arrays, please create PDEF of GENERAL type that is better documented.

Once more, the problem is in reading not the pdef mask file, but
in reading from your netsdf file all 67420 values along the first (x or lon)
dimension with all other dimensions fixed! It crashes netcdf library
and then grads, I guess.

In Grads prior version 1.9 the pdef do not worked for netcdf files at all
due to this problem, but worked for binary files.
>From 1.9 it worked, but already required to use nx and ny
instead of "nx*ny 1" for FILE type pdefs in case of netcdf files,
except that your netsdf file really has
an internal structure with "67420*1" spatial grid.

Good luck to you!

So the "native grid" really is 67420 x 1. The problem was that in the pdef data file (WFD_0p5deg_pdefData.gra in my example below), I had values of zero for the index (or offset) variable over the sea - i.e. the locations that I didn't have data for. These would have been better set to the missing data value. At v1.9.b4, the zeroes worked fine (and I was blissfully unaware that GrADS was struggling with different offset values for GRIB and non-GRIB files). At v2.0.a9 presumably GrADS notes that I don't have a GRIB file and tests the offsets; when it finds a zero it fails (rather dramatically with a core dump!).

Subject: [gradsusr] GrADS Return Code 141
Message-ID: <CAMaBtSkkFVKiejO3uLJm5eVJON1n3+MqfSLb2od+tYSRTyCkaw@mail.gmail.com>

Hello,

in my setup I am running into a strange problem right now. I am
calling a shell script containing a call to grads from a remote
server. When I invoke my shell script manually from the remote server,
everything is working fine - however when running through cron, grads
silently crashes. Nothing is written on both STDOUT or STDERR. The
only thing that I can get is that grads gives a return code 141 in the
shell after failing.

Can you tell me what this return code means? Do you have any idea why
my job can be run manually but not from cron?

Best regards,
Jonas Kaufmann

Subject: [gradsusr] Missing variables in 3-d fwrite binary file
Message-ID: <4E2971D2.6050800@meridian-enviro.com>

Good morning.

I'm attempting to configure some post-processing subroutines for several 
parameters I find useful. For my pathfinder case, I am creating a binary 
file using "fwrite" to store four parameters. Each parameter varies in 
the horizontal plane, but not in the vertical (i.e. only one vertical 
level is computed). When I output a single timestep, I can open and 
retrieve the data file and the data display correctly. If I write each 
variable twice, once for each time step, I can retrieve the first time 
step, but not the second. At present I'm feeding commands into the 
command-line interpreter rather than executing a script. I've seen 
examples in the archives discussing varying the time dimension by way of 
a "while" loop. Since I'm entering the commands individually the result 
/should/ be the same as if run from a script.

I'm not sure where I'm making my mistake in the process, so any guidance 
would be appreciated.

Input data is the North American Mesoscale (NAM) 40 km model. I am 
computing values for "t 1" and "t 2" during this trial period.  The 
variables utilized in the process are "cpd", "isenps", "u", and "v". 
Command sequence is first, followed by the .ctl file. I use a homemade 
script file, "compute_cpd.gs", to conduct the necessary calculations. 
This script accepts three arguments, Theta surface (in Kelvin), grid 
skip, and working file number. compute_cpd.gs returns cpd, isenps, u, 
and v. In this case, "z" in NAM-2011072200.dat represents the "theta" 
level for the isentropic surface.

--- Command Listing ---
open NAM-2011072200.ctl

I looked through the GrADS source code, specifically gscrpt.c file and the 'printf' function is used.

The 'printf' always goes to stdout.  Had it been fprintf(FILE *somefp,...) then maybe it could have been.

However, I don't think the original designers (aka Brian Doty) was concerned about writing to stderr.

Hi John,

thanks for your answer. I know how to redirect channels on the command line.
But how to decide IN the script, what should go to stderr and what to stdout, 'say' always put the output to stdout.
So in bash i would do echo "foobar" 1>&2 to get the foobar to the stderr, how can i do this in GrADS? Is there a way?

Simon

There could be a number of reasons. Bernd's reply is true in that a cron script does not set a PATH and so by sourcing your profile or .bashrc files it will establish your environment. It is easier to put those PATH assignments in the cron script itself. Add the GrADS variables (GADDIR and GASCRP) as well to find the library scripts.

Second, the error code 141 means it is a SIGPIPE error. 141=128+13. 13 indicates a pipe error. 128 is the bash script error.

Third, it could be related to the resources on your machine itself could be the problem.

Can you give us your script?

Subject: [gradsusr] GrADS Return Code 141

Hello,

in my setup I am running into a strange problem right now. I am calling a shell script containing a call to grads from a remote server. When I invoke my shell script manually from the remote server, everything is working fine - however when running through cron, grads silently crashes. Nothing is written on both STDOUT or STDERR. The only thing that I can get is that grads gives a return code 141 in the shell after failing.

Can you tell me what this return code means? Do you have any idea why my job can be run manually but not from cron?

Best regards,
Jonas Kaufmann

Hi Teresa,

sorry for replying so late, i had some personal issues. well I have some
difficulties with this technique since I have statistically significant
values both negative and positive, so when i do set cmin or cmax, it will
block out the others. Is there a way to set it to absolute values?

With regards to scorr, I am of the understanding that grads correlates the
final spatial distribution of both and thus producing one value. I guess for
statistical significance one can use the values on statistics books, and
also consider the resolution of the image to obtain n

Regards,

James

Hello,

I have examined the environment of the calls on both my grads machine
and my remote machines. There are three machines involved in this: two
remote machines where WRF computations are run (these are located in
different data centers and have a slightly different setup) and my
grads machine where the output of the WRF computation is pushed and
then a script is started via ssh.

So the basic script on the remote machine looks like this:
- wait for new data from the forecast model
- scp the data to the grads machine
- ssh grads_machine image_generation_script.sh

The image_generation_script.sh running on the grads server is also quite easy:
- set up environment variables
- perl script to generate a grads script
- grads -b -l -c my_generated_script.gs

I have compared the environments on both the remote machines as the
script is run via cron, and the environment variables are exactly the
same on both machines. On the grads machine, I have also done this,
and the environment also matches there when being called from both
remote machines. There are two things that I don't get:
- on one remote machine everything is working fine, and the other one fails
- if I start the script on my failing remote machine manually,
everything works fine, but not when it gets executed by cron

Is there a way to get any additional output or debug information from
grads? Do you have any other hints what I could try?

Best regards and thank you for your help!

Jonas

That's fits my third guess that it fails on a busy machine.

What is the hardware, the operating system, the memory (vmstat,free), and the ulimit of your space  on both machines.

Message-ID: <CAHBht21kN88RLVQ8u_+mG_ZRxgzKfHsO-jpXB=Y_LgSdhjuaGg@mail.gmail.com>

*Dear GrADS users,

I have downloaded synoptic monthly means analysis data from ECMWF for
specific humidity at 1000 pressure level both in netcdf and grib format
(This is the same data in grib & netcdf format for three months of 1989). I
encountered a bug or some issue in perl script (grib2ctl.pl) that generates
GrADS readable control file for the grib data set. I am attaching grib file
and control file made by grib2ctl.pl as well as index file generated by
gribmap. The bug is that synoptic monthly means data have 4 time steps (at
00, 06, 12, & 18) for each month but grib2ctl.pl makes 4 time steps in each
day instead of 4 time step in a month. When I opened the ctl file in GrADS,
it display some values and shows rest as all undefined values. I even
changed time in ctl manually and generate index again but the problem is yet
unresolved. Where is the issue? Does anyone already encountered the same
problem. Please see attached files for your satisfaction.

Mubashar,

Are you sure the data is what you expect? Does your grib file have 4 time steps x 30 some days in the month of interest? Or are you positive it is just those for time steps averaged for each day in the month?

Hello,

the machine itself was okay - however I have found the answer in the
mean time. In my original script running on my WRF server I tried to
capture the output of the remote ssh command for debugging using:
ssh grads_machine image_generation_script.sh & > logfile 2> errorfile

I changed this to (notice the brackets):
(ssh grads_machine image_generation_script.sh &) > logfile 2> errorfile

...and from this point on everything went fine - although I am not
sure why this failed at all...

Anyway, thank you for your help and for your hints on where to look further!

Best regards and have a nice weekend!

Jonas Kaufmann

Hi Kevin:

It looks like in your NAM-2011072200.ctl file you are defining one 
vertical level:

zdef 1 levels 315

but you then assign two levels to each variable:

cpd                   2 99 Condensation Pressure Deficit (mb)
isenps                2 99 Pressure (mb)
u                     2 99 Zonal component of wind (ms^-1)
v                     2 99 Meridional component of wind (ms^-1)

I think if you change the "2's" above with "1", or for surface you can 
have "0",
it should work ok.

Subject: [gradsusr] incorrect time steps
Message-ID: <1311354464.42717.YahooMailNeo@web31901.mail.mud.yahoo.com>

Hi,
I have used CDO operators to create monthly netCDF file from daily data. The timestamp of the resulting file when viewed in CDO is:

1989-01-31T00:00:00
1989-02-28T00:00:00
1989-03-31T00:00:00
1989-04-30T00:00:00
......
.....

But the timestep of the same file in grads is:

1989-01-31:0
1989:3:3:0

1989:3:31:0
1989:5:1:0
....
....

This is different and I guess is causing problem in time series plot etc. How can I overcome the problem?

I am using grads version 2.0.a7.oga.3 in Linux OS.

Any advice will be highly appreciated.

Hi Mason,

Yes of course it is synoptic monthly means at 00, 06, 12 and 18 UTC. plz
have a look on the attached netcdf, grib files of the same data set and see
the clear difference between netcdf and grib2ctl.pl generated control file.

Hello
i am trying to plot muti images in the same panel ,i am trying to use the
panels.gsf .i wanna to usse it in command line mode
so how can i use the global variable (_vpg.p) in the panels.gsf to define
the number of plot i wanna to plot .
for example
*open plot.ctl*
*panels.gsf 2 2 *
*_vpg.1*
*d u*
*_vpg.2 *
*d v*
thanks in advance

Mubashar,

    The grib ctl file looks fine. If you want the 00Z jan, "set time  
00z1jan1989". 
If you want the 12Z feb mean, "set time 12Z1feb1989".  GrADS requires the
time variable to have fixed time steps so you will have undefined data 
for all but
the first day of the month.

Hai,

I want to plot surface current above sst. For this I am using Argo sst data
and
Oscar surface current data. The details of this files are given below:
----------------------------------------------------------------------------------------
ga-> q file 1
File 1 : 1x1 Monthly gridded climatology on Standard Levels
  Descriptor: Gr_clm_temp_lev_0_2000m.nc
  Binary: Gr_clm_temp_lev_0_2000m.nc
  Type = Gridded
  Xsize = 360  Ysize = 180  Zsize = 27  Tsize = 12  Esize = 1
  Number of Variables = 1
     temp  27  t,z,y,x  argo temperature (degc)
ga-> q file 2
File 2 : OSCAR Surface current data climatology 2003-2010 averaged
  Descriptor: oscar2003_2010clim.ctl
  Binary: oscar2003_2010clim.bin
  Type = Gridded
  Xsize = 360  Ysize = 120  Zsize = 1  Tsize = 12  Esize = 1
  Number of Variables = 2
     u  1  99  zonal velocity component
     v  1  99  meridional velocity component
-------------------------------------------------------------------------------------------

I plotted the sst , but when I am trying to plot the surface current above
sst, I am getting
the following warning message.
--------------------------------------------------------------------------------------------
........................................

Sudev,

The problem (I think) is that your current time dimensions settings do not overlap with the times available in your file #2.

Your second file has 12 times but the line in the error message
"Grid limits of request:? X = 35 111? Y = 40 88? Z = 1 1? T = -119987 -119987? E = 1 1"
indicates that the time you have selected from the SST file is before the start of the surface current data (t=-119987).

You can override the current time dimension settings (i.e. choose a particular time) by using, e.g.
d u.2(t=1);v.2(t=1)
to plot the first time of surface current data. You can choose any of the 12 times available in this way.

Doug

Jim,

I thought those values represented the time step. After changing them to 
"1" as you suggested, the data are what I was expecting. My next step is 
creating multiple levels corresponding to numerous isentropic levels. 
For each level I add, I'll increment the "1"s to the number of vertical 
levels.

Many, many thanks for you suggestion.

Dear all
      I tried to write the grads out put values into a ascii file by using
the fprintf.gs script. I tried the following command

> set x 1 54 (since the .dat file has 54 longitude and 36 latitude points)
> set t 25
> fprintf  t2-273.15   T2-24hr.csv  %g, 54

but the file T2-24hr.csv  has only two rows of data instead of 36 rows of
data. What may be the error with this script or command.

waiting for your kind reply

thanking you
with regards
Dipak Sahu

Message-ID: <CA+_3LvrzGiTY_nsK33FKTuX==uW6o0bVGQFEqj5nHS84yv8AqQ@mail.gmail.com>

Hi guys,

I have a question about the variable 'HFX' that from the ARWpost .ctl
file. The description reads 'upward heat flux at the surface', and I
wanted to know if this meant total heat flux or simply sensible heat
flux.

Any ideas are appreciated!

Dear all,

i have a problem with opening a file.
I use (GrADS) Version 2.0.a9 on Suse

ga-> sdfopen GKSS-2.nc
Scanning self-describing file:  GKSS-2.nc
gadsdf: Error parsing time_units for SDF file.

the format is as follows:
(from ncdump)

         double time(time) ;
                 time:units = "day as %Y%m%d.%f" ;
                 time:calendar = "proleptic_gregorian" ;
                 time:axis = "t" ;
                 time:long_name = "time" ;

So i think this is valid format? Can anyone tell my what is wrong?

Best Regards,
Simon

 time:units = "day as %Y%m%d.%f"   It does not follow GOARDS
conventions which is used in 'sdfopen' function. So you need to write
a control file to tell GrADS the dimensions and variables in the data
set. You have to use 'xdfopen' or 'open' commands to open the data
file.

Dear Yaqiang,

thank you for the information, where can i find the GrADS conventions to 
know which  format is ok,  and which not?
I'm very new to GrADS, so can you give me a source where i can find a 
example of a control file? I have no idea how to do that.

Best Regards,
Simon

inside a script you could redirect using unix shell
e.g.:
'!echo ERROR ON FILE >&2'

I've just tried and it seems to work

Subject: [gradsusr] error with fprintf command (dipak sahu)
Message-ID: <CAMUironTPfwN=9SeKSFADRR66rsBz6GLk0P+nKUbf+h2CO9+PQ@mail.gmail.com>

hi Dipak,
 I think with the fprintf function u will have to set y values also. From
the script u sent

> set x 1 54 (since the .dat file has 54 longitude and 36 latitude points)
> set t 25
> fprintf  t2-273.15   T2-24hr.csv  %g, 54
u are varying x dimension at some constant time, what about y?? But then
also your output file should contain only one row of 54 values since by
default grads must have set latitude to the first value in the domain. Try
by giving some value to y dimension.

Bye
Roopa

Hi Dipak,

*
Look at the foll two lines
ga->* set x 1 72
*ga->* fprintf ts ts.csv %g, 72 0

I think you should give

set x 1 54
> set t 25
> fprintf  t2-273.15   T2-24hr.csv  %g, 54 0
try it and let me know or else if poss send me the data i will check.

Bye
Roopa

This is a bug that has been fixed for the next release. The problem  
was that the subroutime gxqdrgb() needed to be moved from gxhpng.c to  
gxX.c. It will compile as is if you enable the printim command, which  
needs zlib, libpng, libjpeg, and libgd. Also, you need to add -lrt to  
the list of libraries to link with, that will fix the undefined  
reference to clock_gettime. Please have a look at http://iges.org/grads/gadoc/supplibs.html

You did not include the ncdump output that shows the metadata for the  
coordinate axis "lev" -- it may have been insufficient. If that is the  
case, then GrADS won't recognize variables that use that coordinate  
axis. Furthermore, you need to include the version of GrADS you are  
using, since the sdfopen interface has changed over time and this  
information may be quite relevant. After you have sdfopen'ed your  
file, try a 'q file' and see if it has found a z-axis with levels that  
match the ncdump output. If not, then you will need to write a  
descriptor file, either a short version for the xdfopen command, or a  
complete one for the open command. The documentation is at http://iges.org/grads/gadoc/SDFdescriptorfile.html

Subject: [gradsusr] LFC calculation
Message-ID: <4E301AEA.7030108@meridian-enviro.com>

Meredith,

I ran into a similar problem while attempting to compute condensation 
pressure deficit (CPD). My solution was to derive an equation for my 
value of interest and then implement it in GrADS. Deriving the equation 
was the most difficult portion of this task. Once I had that in hand, I 
used several steps to bootstrap the solution in GrADS. For example, my 
CPD equation requires virtual temperature and the change in height by 
way of the hypsometric equation. For one step, I calculate the virtual 
temperature grid. In the next step I use the calculated virtual 
temperature grid in the hypsometric equation to find the change in 
height. For my way of thinking, a step-wise process, taking each piece 
in a small chunk, is easiest to comprehend during the testing phase. 
After you verify your solution works, you can refine the method to 
improve your processing efficiency.

In my experience, you can "define [var]=[eqn]" to create the appropriate 
gridded variable. If you have x and y varying (for a single time), 
you'll calculate the variable for each gridpoint in your domain or vary 
x, y, and t for multiple time steps in your domain.

Hope this helps.

+++Begin copied text+++

Hi Everyone,

I'm looking to plot a contour plot of LFC height, similar to the graphic
on the SPC Mesoscale Analysis page, my control file does not output LFC
directly,  is there anyway I can calculate this in grads?

Thanks for your help.

Meredith

You may just need to set your time interval to something different. Try

set t 1 50
in grads command line

to see the temperature in kelvin for the first 50 timesteps. You should see
contour plots pop up really quickly, starting from the first timestep and
stop at the 50th timestep for your domain. I hope that works.

Estefan?a:

Another thing to check is your file names.  In the ctl file you specify:
*Eta_exp110km1960010100+%y4%m2%d2%h2.bin
*which means when/if you "set t 1", it will look for a file called:
*Eta_exp110km1960010100+1960010100.bin

*If you do not have such a file, you'll get all undefined values.  I suspect
that the first part of the file probably changes as well?  Or maybe you
have the data files in a subdirectory?

Turns out the subsetting *is* the culprit... changed it from the CONUS to
US/Canada/Alaska and it actually downloads (insignificantly) faster... I'll
try testing raw data downloads sometime too (especially since I can use
parallel connections without bogging down the NOMADS server). Oh, and I
implemented the staggered downloads and now have a lag of about 2-4 seconds
for the first map and 12-20 seconds for the last map (GrADS is really fast
at generating maps... at least when the right settings are used on printim).

Thanks,
Joey

Hi all,

I finally solved my problem by converting the time axis from absolute to 
relative with "cdo -r copy inputfile outputfile".

HB,

Here's an example of plotting vertically averaged wind streamlines for a
single timestep from a forecast model:

'set time 00z30jul2011'
'define u=ave(ugrdprs,lev=1000,lev=300)'
'define v=ave(vgrdprs,lev=1000,lev=300)'
'set gxout stream'
'd u;v'

Hi you all!

Does anybody know how to draw the orography used in the NCEP/NCAR reanalysis
1 datasets using GRADS ?

I have downloaded teh file orog.spec.nc but I cannot think of how to use it.

Many thanks.

Subject: [gradsusr] how to display collected data when T varies
Message-ID: <BLU136-W297E5BB07055DAA09F82C1EA370@phx.gbl>


Hi All,
Have a set of WRF output data, post processed into GRADS data (de.ctl and de.dat). The data is for couple of days with time increment 3hrs. 
Want to plot out the average OLR along a slant line (cross section, say from 40E 10N to 70E 25N) with 10 degrees in latitude. We can do this easily if the averaging is along a straight line (e.g. ave(olr,lat=5,lat=15) for lon 40 70). 
Tried "collect" and "gr2stn". "collect" works for data varying in Z or T; I can collect the averaged values of OLR with varying T. However, "gr2stn" works only for varying Z, not T. 
Question: How do I display the collected data with varying T? It seems that I can't use "gr2stn". 
Thanks. 
Liping

Hi Eduardo.
You can download the topo data from this link:
http://users.ictp.it/~pubregcm/RegCM3/globedat.htm#part5
for display Topography in contour or shaded format just type these command
in GrADS terminal:
set lat x1 x2
set lon y1 y2
set gxout contour(or shaded)
d EXPR

Subject: [gradsusr] define a simple scalar
Message-ID: <4E3454C8.8000003@ucsd.edu>

Hello,

I'm having a problem with what I'm sure is a simple task.  I want to 
define a scalar to convert a slope (i.e. units/year) into a trend line 
over several years.  I'm using this to detrend a time series.   
Basically I just need to construct a simple scalar (i.e. variable = 1 2 
3 4 5...) or a variable that equals the year of each entry of my dataset 
(i.e. variable = 1991 1992 1993 1994 1995...) that I can multiply by my 
slope values.  I can use tloop to create the right dimensions (variable 
= 1 1 1 1 1...) but I can't seem to get the values to increase for each 
time step.

Imagine I could either create a datafile manually and read it in or 
somehow extract the year information from the existing dataset into a 
user defined variable.

Is there an equivalent of 'define variable(t=2) = 2'?  I know this 
syntax is wrong.

Any advice would be appreciated.

Lisa

set t 1
variable1 = const(kanto, 1, -a)
set t 2
variable2 = const(kanto, 2, -a)

where "kanto" is any variable in the file.

AFAIK there is no way to define different timesteps of the same variable in
different ways. A for loop can take care of the trouble involved with using
multiple variables.

Helloo,
          Which data you want to plot using stationgrads.  I know how to
plot rainfall data using station grads. If you want rainfall data to plot
then probably I can help. What you need is to have an ascii file of data.
Let me know your specific requirement.

Helloo, 
Which data you want to plot using stationgrads. I know how to plot rainfall data using station grads. If you want rainfall data to plot then probably I can help. What you need is to have an ascii file of data. Let me know your specific requirement.

Kindly send me one sample of your ascii file including latitude, longitude,
station name year, date , rainfall etc. Let me try and after that I will
send you the programs and required gs files and the procedures needed to
plot the file in grads. Best of luck.

Hi All,

I would to use NCEP/NCAR Wind Speed Data which is available at 2.5 x
2.5 degree for Trend analysis & correction factor. Initially, I would
be interested in undergoing ?two tasks :

1. would like to interpolate the WS data from 2.5x 2.5 degree to 1 x 1
degree using GrADS. I understand GrADS is the best tool for displaying
and interpolating the same. Can anybody help me how to do this, please
send me codes & conceptual help as well.

2. Secondly, ?I am using Window as Operating system and I need to
install the same in my System. I have tried quite often but was
unsuccessful.While installing, it always ask for cywgin ?platform it,
and error message is popped up showing .dll is missing. Please help my
in this regards and send a complete packet of setup files and
installation guide describing the various steps to be followed in
sequential manner.

Regards,

Zia

Try running GrADS in verbose mode to see what exactly is wrong.

Dear all,

I would like to have your confirmation for this expression in grads:

Exponential: 'exp (expression)' is it true?

And how if I want to make something like:

(a+b)*(a+b) = (a+b)^2 is that true?
(a+b)*(a+b)*(a+b) = (a+b)^3 is that true?


Thank you,

Hi all,

You can also use CDO if you have Windows. In addition to what Saeed had
said, you can also :

cdo -r mergetime ifile1 ifile2 ifile3 ofile

depending on what you need.

Serge

Dear all,

I found it, Thank you anyway.
For power, just 'pow(exp,yourpower)' where exp your expression and yourpower
the power you want.
So it becomes:
(a+b)*(a+b)*(a+b) = pow ((a+b),3)

Regards,

Serge

Message-ID: <06B0A85218E0A34EBBFFF4435CA4BAA403C8F691F3@sawsptahub01.saws.local>

I have tried to avoid the page (X,Y) boundary markings by using the attached script but the marks always appears. The IF STATEMENT  does not appear to do the trick; how do I make sure that the marks at the boundaries do not appear but the interior marks appear?
For instance,

1)      if('bcx'!='xx1'| 'bcx'!='xx2' | 'bcy'!='yy1' | 'bcy'!='yy2')
'draw mark 4 'bcx' 'bcy' .1'
else
'draw mark 0 'bcx' 'bcy' .1'
Endif
RESULT IN MARKINGS ANYWAY,




2)if('bcx'='xx1'| 'bcx'='xx2' | 'bcy'='yy1' | 'bcy'='yy2')
'draw mark 0 'bcx' 'bcy' .1'
else
'draw mark 4 'bcx' 'bcy' .1'
Endif
STILL RESULT IN THE MARKINGS, AND

 3) if('bcx'>'xx1'| 'bcx'<'xx2' | 'bcy'>'yy1' | 'bcy'<'yy2')
'draw mark 4 'bcx' 'bcy' .1'
Endif

MARKINGS STILL AT THE BOUNDARIES.

NOTE: For testing choose BCX=XX1,BCY=YY1 or BCX=XX1,BCY=YY2 or BCX=XX2, BCY=YY1, or BCX=XX2, BCY=YY2.

 BOUNDARY MARKS/ EXCLUSION OF BOUNDARY MARKS
Message-ID: <06B0A85218E0A34EBBFFF4435CA4BAA403C8F691F5@sawsptahub01.saws.local>

I have tried to avoid the page (X,Y) boundary markings by using the attached script but the marks always appears. The IF STATEMENT  does not appear to do the trick; how do I make sure that the marks at the boundaries do not appear but only the interior marks appear?
For instance,

1)      if('bcx'!='xx1'| 'bcx'!='xx2' | 'bcy'!='yy1' | 'bcy'!='yy2')
'draw mark 4 'bcx' 'bcy' .1'
else
'draw mark 0 'bcx' 'bcy' .1'
Endif
RESULT IN MARKINGS ANYWAY,




2)if('bcx'='xx1'| 'bcx'='xx2' | 'bcy'='yy1' | 'bcy'='yy2')
'draw mark 0 'bcx' 'bcy' .1'
else
'draw mark 4 'bcx' 'bcy' .1'
Endif
STILL RESULT IN THE MARKINGS, AND

 3) if('bcx'>'xx1'| 'bcx'<'xx2' | 'bcy'>'yy1' | 'bcy'<'yy2')
'draw mark 4 'bcx' 'bcy' .1'
Endif

MARKINGS STILL AT THE BOUNDARIES.

NOTE: For testing choose boundary points like BCX=XX1,BCY=YY1 or BCX=XX1,BCY=YY2 or BCX=XX2, BCY=YY1, or BCX=XX2, BCY=YY2, and
             interior points like BCX=2.0 and BCY=5.0, and BCX=5.5 and BCY=6.8.

there is a conceputal error, let's understand the meaning of:

  if('bcx'!='xx1' ...

this logaical is always false, because 'bcx' is a string, 'xx1' is a
string and they are different


in your script appears:

  'draw mark 4 'bcx' 'bcy' .1'

then it is clear that bcx is a scalar (it has a value)
...

correct the logical expr in this way:

  if(bcx!=xx1 ...

hoping it helps
bye bye

Subject: [gradsusr] correlation map
Message-ID: <CAOXKaKD3cZXGvrLaPtg_PAp_PDaALUW+xtDW+MN8Ex_NsJ5Xyg@mail.gmail.com>

Hi

I have 20 year composite in which i have two variables (meridional and zonal
wind speeds). I'm using the NCEP/NCAR reanalysis data from 1989 to nov2008.
I need a (spatial) map of correlation coefficients for that period.

I've explored the functions tcorr and scorr, but none of them is suitable
for that. The tcorr function requires that the first variable is only a
function of time, which is not in my case.

Thanks is advance

Hi all,

I was wondering if using fwrite to write a binary file if it is possible to
specify the format to avoid having it in stream. For example, the data be
written at a format like 8e10.3 to have a formatted file. How to do it?

thanks

Dear all,

My file contains 2 variables a and b. I have the following condition:

if a>b => c=b
if a<b => c=a

so: d=c/b

in my .gs file, I tried:

'!if (a> b)'
'c= b'
'!else'
'c= a'
'!endif'
'define d=c/b'

but it gives syntax error.

Then I tried to define the c like:

'!if (a> b)'
'define c= b'
'!else'
'define c= a'
'!endif'
'define d=c/b'

Again, syntax error.

ERROR:
sh: -c: line 1: syntax error: unexpected end of file
sh: -c: line 0: syntax error near unexpected token `else'
sh: -c: line 0: `else'
sh: endif: command not found


Thank you in advance,

Dear GRads Users,

I've scoured the mailing lists and been back and forward with ECWMF. I've two sample files from them (ECWMF GRIB v1) which I simply can not get translated properly. If anyone can offer some assistance I'd greatly appreciate it before I go and do a lot of installing of ECWMF software that may not be needed. ECWMF does not have their GRIB2 versions of this data.

I've attached both samples - they are supposed to be weekly anomalies of 2m temperature and precipitation.

Many thanks.

Here's a descriptor for the T2A file:

dset ^enfo_2TA.grib
index ^enfo_2TA.grib.idx
undef 9.999E+20
title enfo_2TA.grib
dtype grib
options yrev

xdef 120 linear 0.000000 3.000000

zdef 1 linear 1 1
vars 1
t2a  0 167,1,0  surface 2 metre temperature anomaly [K]
endvars

And when you run gribmap, use the -e option.
  # gribmap -e -v -i enfo_2TA.ctl

A pilot project in Nicaragua on heavy rainfall and landslide early 
warning in near real time:
http://georiesgos-ca.ineter.gob.ni/lluvia/nesdis/gif/index.html

You have to place the cursor over the map to see a movie. The single GIF 
frames are made with Grads from the NESDIS Hydroestimator data and are 
then put together with ImageMagick to generate the animation. On the 
left you can select a region or country in the Central America-Caribbean 
area.

The system is capable to generate alert messages by email when strong 
rain occurs over a landslide prone area, e.g. volcanoes in Central America.

Subject: [gradsusr] Isentropic variables and ctl files
Message-ID: <CAK55UEfqP_CyoSQaf6rNjf-fsc1Jih7XXcn7ogu9PEKapT+EJQ@mail.gmail.com>

Hello, everyone.

I'm working with Bob Hart's isentropic field script. One of my goals is to
process guidance for several isentropic levels, store the variables in a
file (NetCDF is the method of choice, at present), then retrieve each of the
isentropic levels by way of the "set lev" command with each of the
isentropic surfaces listed in the .ctl file under "zdef 9 levels" as  "290
292 294 296 298 300 302 304 306". Is there a method or process to execute
the isentropic script several times for several isentropic surfaces and
store the output in a single variable? For testing I'm working with NAM
data.

Many thanks,

Kevin Huyck.

Are you keeping track of GDS servers? Or other "non-graphic" sites that
still have grads as a backend? For example, our "download tool" sites, e.g.,


http://portal.nccs.nasa.gov/cgi-lats4d/webform.cgi?&i=GEOS-5/fp/0.25_deg/assim/inst3_2d_asm_Nx

Message-ID: <CAHCbKuNazS2GLtGGK+Lpw4-tgnRrRK7rc3_ov888qaPr44Mz4Q@mail.gmail.com>

Hello.
I am using GrADS version 2.0.a7.oga.3.  I have a long paleoclimate
timeseries going from 3800 years before present to 12300 years before
present.  When I plot a section of this time series (i.e. 3800 to 7000) the
x-axis labels appear normal (i.e. 3000 4000 5000 ...).  However, when I
attempt to plot the entire timeseries the x-axis labels disappear except for
a single label appearing at 4000.  Attached are screen shots showing the
situation.  Any suggestions on how to remedy this would be greatly
appreciated.

Thanks!

Best,
Max

Message-ID: <20110708150313.y5vi2zjzwc4gkgwc@cubmail.cc.columbia.edu>

Hi Gradusers,
I am trying to get a temporal correlation of two data sets that also  
vary in x and y. Just to give you some context, I am comparing model  
data to observed data over a 52 year span. I wrote a script that  
calculates point by point temporal correlation by use of the tcorr  
function, but it is unusable for me as it is very inefficent! Was  
wondering if anyone had a correlation script/ suggestions for me?
here is the script:

***function to plot a temporal correlation with a spatial loop
function correlation(arg)

startx=subwrd(arg,1)
endx=subwrd(arg,2)
starty=subwrd(arg,3)
endy=subwrd(arg,4)
startt=subwrd(arg,5)
endt=subwrd(arg,6)

say 'longitude = ' startx ' to ' endx
say 'latitude = ' starty ' to ' endy
say 'years = ' startt ' to ' endt

x=startx
while (x<= endx)
'set x ' x
y=starty
while (y <= endy)
'set y ' y
'set t ' startt
'd tcorr(prcp.1,prcp.2,t=' startt ',t=' endt ')'
y=y+1
endwhile
x=x+1
endwhile
exit

Hey Everyone,

A while back I received some help with displaying WRF output in GrADS using ARWPost.  Thanks!  Now, I have a question about some of the fields.  When I display some fields, the look normal and as expected. But, others look odd.  I have attached an image of my 'w' field at 500 hPa.  Some other fields, such as the boundary layer height, also share this pattern.  Other fields, such as the 'u' and 'v' winds, look fine.  I was wondering if this looks like an error somewhere in my ARWPost run or an error in my WRF run?  Thanks an advance for any help!

You could try to comment "options byteswapped" in the ctl file.

If Yaqiang's idea doesn't work, I would try re-running ARWpost with fewer
variables.  I doubt you really need all of those variables, and if your .dat
file is too large, there may be a problem with how it displays data.  Also,
it appears your XDEF and YDEF lines could be simplified by putting
XDEF 210 LINEAR 0.0217
or something like that, since all of your levels appear to be equally
spaced.

Thanks Saeed.
Unfortunately, it seems the set xlabs and set vrange2 commands do not
operate on the x-axis when it represents time. Perhaps I need to edit how
time is defined in the .cdl file.

Best,
Max

Introducing InstantWeatherMaps.com, a new weather model website. The site
has a lag (from when the raw data appears on the NOMADS server) of 10-30
seconds, compared to around 90 seconds for the closest other free site (the
new beta NCEP site). I offer over 150 variables, including Kuchera-method
snowfall (otherwise only found on Earl Barker's site, which has a lag of
around 30-90 minutes). Nearly a half-million GFS model maps are on my server
at any given time. I would appreciate any suggestions as to future
enhancements I could make to my site.

Consider using anti-aliasing fonts and lines, e.g.,

     http://portal.nccs.nasa.gov/cgi-yotc/fp_wx.cgi

This is obtained by replacing printim with gxyat. Make sure to read the
documentation for a trick to reduce the size of the image files (pipe to
pngquant) , something that would be important for you with 1/2 million
plots. Notice that you will need the opengrads bundle for this,


http://opengrads.org/wiki/index.php?title=Installing_the_OpenGrADS_Bundle

Type

ga-> gxyat

for a manual page.

Thanks for the suggestion. I ran tests of gxyat vs printim and found that
gxyat outputs roughly 4 images per second, and printim outputs roughly 20
images per second (when set to GIF mode, which about 65% faster than PNG at
the expense of a roughly 15% larger file size). I will keep using printim
for the forseeable future, since output speed is paramount to my site's
operation. I do have another question, though, which I will ask in a
separate message.

Subject: [gradsusr] NOMADS download speeds
Message-ID: <CAJv4EQqs3FZN=DqHTgh_R+ivDHTwv9NfcipU_TSszgO=48LVpA@mail.gmail.com>

Is there any way to speed up downloads from the NOMADS server (
http://nomads.ncep.noaa.gov/cgi-bin/filter_gfs_hd.pl)? I currently run a
site that spends around 6-8 seconds per forecast hour generating maps.
Having said that, it is quite frustrating to see download times for 1 MB of
GRIB data exceed 10 seconds at times. I currently use 4 wget sessions in
parallel to handle the downloading, and I only sleep for 2 seconds instead
of 10 when polling the NOMADS server to check when the next file is
available, so as you can see I am very speed-oriented. Is there any way to
download faster, or is partial-downloading (downloading part of the GRIB
file, generating the relevant maps for the first part while the rest
downloads, then generating the maps for the rest) the fastest way of doing
this?

Subject: [gradsusr] Computation of thermodynamic Indices
Message-ID: <BLU152-w42402221CC2A51228FAB7F8A450@phx.gbl>


Dear All, 
This problem is not particularly pertaining to Grads but  I am still putting it across in anticipation of a possible help.


It goes like this, I want to compute all the Standard Indices  
( like Showalter, K, SWEAT, CAPE, CINE  etc)
from the Rs data of a station. 


I am able to compute only LCL and then the moist adiabat (using the conservation of MOIST static energy) 
and I have computed the LCL from the RS data and then constructed the moist adiabat of the parcel till 200hPa. Part of the output of moist adiabat looks like this, 

(I)
INPUT LCL

 P T Z
 871.0 294.6 312.0
 MOIST ADIABAT
 P Z T Q NO OF ITRN
 871.0 312.0 294.6 .1952E-01 .3476E+06 0
 870.0 322.0 294.5 .1950E-01 .3476E+06 39
 869.0 332.1 294.5 .1947E-01 .3476E+06 39
 868.0 342.1 294.4 .1945E-01 .3476E+06 40
 867.0 352.2 294.4 .1942E-01 .3476E+06 39
 866.0 362.2 294.4 .1940E-01 .3476E+06 39
 865.0 372.3 294.3 .1938E-01 .3476E+06 40
 864.0 382.4 294.3 .1935E-01 .3476E+06 39

"MOIST.DAT" 676 lines, 44480 characters

(II)
My RS data of a station is at an interval of 50hPa and looks like this (Ht, TT, Td, WS, WD at different levels)


1981 03 10 00 2 1026 20.6 16.8 155 02 1520 18.6 11.2 201 04 ^M
1981 03 10 00 3 2038 15.6 8.2 195 03 2584 12.4 3.8 079 02 
 3159 8.4 -5.3 105 04 3768 4.8 044 03 




Kindly help me reg the computation of CAPE and CINE after I construct the MOIST adiabat for a station.

Dear forum members,

I met a specific problem with GrADS plotting shape files.
The first time with Linux applications I met a problem when
all graphical KDE system is shut-down and rebooted,
like MS Window!
All and any do not saved results
of any applications in the running session are lost...
Please be careful if you will try to reproduce this behavior!

GrADS version is
Config: v2.0.a9 little-endian readline printim grib2 netcdf hdf4-sds
hdf5 opendap-grids,stn geotiff shapefile,
Linux workstations runs openSUSE 10.3 (X86-64),
kernel version 2.6.22.19-0.4-default

After downloading some shape files from the
http://www.diva-gis.org/Data,
namely "countries" from the Global level data
and South Korea administrative boundaries
from the Country level data,
I permanently have this problem if
run next sequence of commands.
I tested it with the Word Ocean Atlas 2005 netcdf
files:

d something
draw shp countries
draw shp KOR_adm0

... and nothing more on the screen,
the new graphical session starts.

As I believe that all shape files are just data,
there must be some problem with memory
operations in the GrADS, I guess.

Individual shape files are plotted without problem,
including both mentioned, as just shapes or as filled polygons.

Does somebody had similar problem and do it is possible
to avoid such surprises with these or other shape files?

Sincerely yours,
Sergey Varlamov

Dear Nagaraju,

Thank you for your answer but I've already found it. Below is the script:

if (a> b)
'define c= b'
else
'define c= a'
endif
'define d=c/b'

Anyway, the if expression in grads is not accompanied by then.

Regards,

Serge

Joey,

       My impression of the nomads server is that it is very fast.  
However, I have a very fast link to the internet and
the site is only 10 miles away.

      You are using the GFS which has 0.5 degree resolution (260K 
points) and you are using the filter program
which can create a regional subset.   If you are asking for a 5x5 grid, 
then your download speeds will be
slow.  After all you have to process 10K points for every point sent to 
you. 

     Another possibility is that you may have run afoul of some 
fair-usage filter.   Every site needs some protection
against denial-of-service attacks and poorly programmed web scripts.  
Anyways the nomads help desk is a more
appropriate source of information than the GrADS user forum.

Hi users,

When I type sdfopen file, I receive:

ga-> sdfopen UCLM_PROMES_CTL_ERAIN_6H_1990_prc.nc
Scanning self-describing file:  UCLM_PROMES_CTL_ERAIN_6H_1990_prc.nc
SDF file has no discernable X coordinate.
ga->

How may I resolve this? May anyone help me?

Thanks a lot,

Guilherme.

Start by reading the documentation:

       http://grads.iges.org/grads/gadoc/SDFdescriptorfile.html

You likely need to create a DDF and use xdfopen.

Message-ID: <CAP9LQ-Wn733OXYynfJ=tZg7wqmRhpYrkpNxYTg5=DOcu0s0XMQ@mail.gmail.com>

I have two 2D model grids that have the same horizontal grid spacing and the
same domain width (so the X-coordinate is the same between the two) and the
same domain height, but different numbers of levels in the vertical.  I wish
to compare the values of some variables such as vertical motion between the
two model grids.  How do I do that?

Are the levels really different, or one file is a subset of the other? Say,
one has fewer mandatory levels. If the latter, use lats4d or write your own
simple script to subset the larger file to make it appear as the first. If
the levels are really different, you will need to perform a remapping from
one vertical grid to another. This remap algorithm can vary from a simple
linear interpolation in log-p to a conservative scheme that preserves
monotonicity, all depends on your application. I usually perform this
remapping outside grads.

No, they're truly different in the sense that probably none of the levels
perfectly match up.  What algorithms do you know of?

Message-ID: <CAG1cdGN6Qr1kiB-5EV_N3yPa7XyLzfaNgdE1O2g5jGqRVHWd6A@mail.gmail.com>

Dear all,

I'm using grads 2.0.a9.oga.1 installed in the c:\ drive of  Windows XP. I
wrote a batch script(.bat) to generate graphical outputs from
http://nomads.ncep.noaa.gov:9090.
The script works if it is   placed in any folder in the C:\ drive but fails
when it is  run from a pendrive, external drive , d:\ drive etc. Among the
content of the script is:  grads -blc "run script.gs"

The following messages were displayed on the execution of the script from an
external drive:

Jeff and Yaqiang,

Thanks for the ideas.  Unfortunately, I still haven't found a solution.  I have figured out a little more about the problem, I think.  It appears that it is the "standard" variables that look odd.  If I display the umet and vmet diagnostic variables, they look great.  But, if I display the standard U and V variables, they look just like W did.  

As you suspected Jeff, I don't need many variables, actually only the U,V, and W wind components.  But, even when just running ARWpost with the 'basic' fields option the variables look crazy.  Any more ideas would be greatly appreciated!

Thanks,
Nick

The netCDF data output from WRF are not follow COARDS or CF
conventions, so the data can't be read directly by many popular
meteorological softwares, including GrADS (I mean with sdfopen
method). I don't understand why WRF group made their data different. I
have no experience on ARWpost tool, but I know something of the netCDF
data format used in WRF, which is defined as 'WRF_OUT' conventions in
MeteoInfo software. So you can try to graph the data using MeteoInfo
temporally before you find a better sollution of it. You could only
use MeteoInfo in Windows system for netCDF data, although it could be
used in Linux for other data formats under the support of mono.

Nick,
Try viewing the raw netCDF output using ncview or use ncks to output the
actual coordinate values of some of the variables so that you can see them.
If the data looks bad when viewing the raw netCDF output, then something
went wrong in your model and ARWpost has nothing to do with it.  If it looks
clean, then it's something with ARWpost.  Let me know what you find out.

First, make sure you have a version of GrADS that supports reading HDF-EOS5 grid files (2.0.a7 or higher).
Below is a sample GrADS control (.ctl) file that will let you read an OMI SO2 level-3 gridded HDF-EOS5 data file:

DSET  OMI-Aura_L3-OMSO2e_2004m1001_v003-2011m0526t144250.he5
DTYPE hdf5_grid

ENDVARS


Note the group paths to the data field variables must be specified in full, and any spaces converted to tilda (~) characters.

You can rename the OMSO2e data files by removing the production date/time from the version (stuff after v003), then you would have 
a file name like OMI-Aura_L3-OMSO2e_2004m1001_v003.he5. With this you could modify the DSET (and add OPTIONS) to the .ctl file

DSET  ^OMI-Aura_L3-OMSO2e_%ym%m%d_v003.he5
OPTIONS template

and then you could read in multiple files for a range of dates (remember to also adjust the TDEF range).

Hi everybody,
I would be grateful to somebody who can clarify the foll point.
I want to check the rainfall output from a particular WRF simulation. Is the
total rain a sum of rainc and rainnc??. if cumulus scheme is not activated
then rainc = 0, so total rain = rainnc.

thanks in advance

Warm regards,
Roopa

what's the name of the precipitation variable you are using?  RAINC is
convective scheme precip, RAINNC is microphysical.  If you sum them, then
you get total precip.

See http://cookbooks.opengrads.org/index.php?title=Recipe-013:_Gridding_and_Plotting_Station_Data
and http://www.iges.org/grads/gadoc/aboutstationdata.html
and http://www.iges.org/grads/gadoc/usingstationdata.html

I see that your precipitation data sometimes is followed by a comma and another value. You should clean that up first.

For more insight from GrADS users, Google using the phrase 'station data site:gradsusr.org'

Message-ID: <979990096.135125.1310756439268.JavaMail.root@mailhub017.itcs.purdue.edu>

Hi, 

I'm trying to plot a timeseries of wind barbs of both WRF output and collected observations.  I'd like to plot WRF wind barbs first, then overlay observation data as wind barbs also.  However, my wrf data is gridded data and my observation data is reading into GrADS based on the 'x' coordinate.  Therefore for the obs data, I must use "set x " to pick out a time range.

Thanks,

If you mean the model.ctl, model.gmp, model.grb files, I usually put them in their own directory, like ~/grads/tutorial, chdir to that directory, and THEN start up grads.  Then you need to make sure that (1) you can find the grads executable and (2) you can find the other grads files, like the fonts and maps.

For #1, you can either (a) add the location of the grads executable to your $PATH variable, (b) set up an alias with the full path of your executable or (c) just type in the whole path of the executable (ugh).  In my case, I have it in my PATH, which includes /Users/clynnes/bin:

~/grads/tutorial>which grads
/Users/clynnes/bin/grads

For #2, make sure you have your GADDIR environment variable set to the directory where you installed the fonts and maps. On my Mac, for instance:

~/grads/tutorial>echo $GADDIR
/Users/clynnes/etc/grads
~/grads/tutorial>ls $GADDIR
dat		font3.dat	lomap.dat	nmap.dat
font0.dat	font4.dat	lowres		stroke.dat
font1.dat	font5.dat	mres		udunits.dat
font2.dat	hires		newmap		worldmap
~/grads/tutorial>

Hello Grads community,

I can see from the tutorial that one can open several different case files in grads(file1, file2 etc) and average the data from these files for subsequent display. Is there an advanced option that would allow me to specify the domain for each case and then average them? I was hoping to use this function to easily complete an average of 25 cases or so but relative to some specific type of event, which requires different domain centering for each case prior to averaging.

The ave() functions allows you to make averages over a (x,y,z,t,e)
hypercube. Because undef values are skipped, you can have averages over very
irregular domains, provided an appropriate mask can be derived either
through an expression or by reading it from a file.  For example, to make a
time average along satellite swaths we could do

define xmean = ave(x+0*sat.2,t=1,t=124)

where "sat" (on file "2") is some gridded (time dependent) satellite
measurement with lots of undefs.

Is it possible to plot a map, without using any parameters? that is simply

And possibly even draw a few dots or crosses at particular locations

I have a few hdf files (below) I would like to open with grads, but I am
finding difficulty using the xdfopen function.

SEVIRI_latitude.raw
SEVIRI_longitude.raw
SEVIRI_readme.txt
mean_seviri_aer_oc_d3_tau550_Aug2005.hdf
mean_seviri_aer_oc_d3_tau550_Dec2005.hdf
mean_seviri_aer_oc_d3_tau550_Jul2005.hdf
mean_seviri_aer_oc_d3_tau550_Jun2005.hdf
mean_seviri_aer_oc_d3_tau550_Nov2005.hdf
mean_seviri_aer_oc_d3_tau550_Oct2005.hdf
mean_seviri_aer_oc_d3_tau550_Sep2005.hdf


I tried to construct a descriptor file but cannot figure out how to access
the information for the coordinates:

DSET mean_seviri_aer_oc_d3_tau550_Aug2005.hdf
TITLE monthly average of the daily total aerosol optical depth at 550 nm
derived from MSG/SEVIRI
UNDEF 99999.0
XDEF dimension1 ? LINEAR ? ?
YDEF dimension2  ? LINEAR ? ?
TDEF dimension3 ? LINEAR ? ?
VARS 1
Aerosol_optical_depth=>aod 1 99 aerosol optical depth
ENDVARS

I don't even know if I am on the right track. Can someone help me get to an
answer please? because I am not managing to follow the help on GrADS index.

I have also attached the text file with the remaining information

Regards,

James

The hdf product is the monthly average of the daily total aerosol optical depth at 550 nm derived from MSG/SEVIRI. Note that it's not only minearal dust. Corresponding images are provided.

Format of SEVIRI latitude et longitude .raw files: binary, float-32, without header, size 3712x3712.

Values give latitude and longitude of each pixel centre of the MSG/SEVIRI full resolution window.

The Mediterranean window position is defined by
rowN rowS colW colE: 356 956 1606 2856.

Dear gradsusers,

i invoke a gradsscript from bash and in case that the script can not 
open a file past to it, i want to give a return code back to the 
bashscript so that it knows, that the gradsscript could not open the file.
I have no idea how to do this. For subfunctions in grads i can use 
return but it seems not to work with the main function.
To exit early on i have to use quit it seems but with quit i can not 
give a return code.

I hope someone have a idea.

Best Regards,
Simon

Dear gradsusers

i can not find any information about sending text to the stderror 
channel of the shell while using the say command. Has some one an idea?

Simon

If you are running GrADS in batch mode you can re-direct output as follows

grads -lbc 'run somescript.gs' 2> say.err 1>&2

In interactive mode there is no output to the screen it simply goes to the file.

Does that answer your question?

Dear James,

Sorry that I disturb you again. The descriptors files you sent me worked
marvelously. I then changed the names of the files just like you mentioned
and modified the descriptor file as indicated as well. Next you can find the

To plot a map with no parameters, first open any file with any parameters
(even the sample file will work). Then do this:

set clevs 0
set ccols 0 0
d param

where param is a valid parameter in that file.

You need to change DSET to:

DSET ^OMI-Aura_L3-OMSO2e_%y4m%m2%d2_v003.he5

and make sure the files are actually named something like:

OMI-Aura_L3-OMSO2e_2004m1001_v003.he5

What I like to do is keep the original files as downloaded from the archive, 
and then set up symbolic links with those types of names above. You can write 
a short Unix shell script to do this:

for file in OMI-Aura_L3-OMSO2e*.he5
do
  ln -s $file `echo $file | cut -c1-33`".he5"
done

I would also set TDEF to:

TDEF  3014 linear 01oct2004 1dy

and then you'll be able to read any of the files through the end of 2012, also 
the first day for OMI data is Oct. 1, 2004 (launch was July 15, 2004).

the 'draw map' command will also do it, but it won't plot any lat/lon lines
or coordinates since it won't have any actual map data to go off of (but it
will give you geo-political boundaries just fine)

Sushant and Diallo,

I found a confusing comment in the maxwind.gs and maxwind2.gs scripts 
referring to "plotting track of hurricane center" (not sure, but 
possibly left over from code copied from another script?), and changed 
the comment to "plotting location of max wind". Please find attached 
updated GrADS scripts maxwind.gs, maxwind2.gs.

Sorry for this confusion,
Chuck

Hello Arlindo,

I need to set a different domain center for each of the time periods in the ave function, like say 1 through 124 in your example. As such, the display would then become geographically irrelevant, asides from attaining a since of scale.

Hello Grads community,

I can see from the tutorial that one can open several different case files in grads(file1, file2 etc) and average the data from these files for subsequent display. Is there an advanced option that would allow me to specify the domain for each case and then average them? I was hoping to use this function to easily complete an average of 25 cases or so but relative to some specific type of event, which requires different domain centering for each case prior to averaging.


The ave() functions allows you to make averages over a (x,y,z,t,e) hypercube. Because undef values are skipped, you can have averages over very irregular domains, provided an appropriate mask can be derived either through an expression or by reading it from a file.  For example, to make a time average along satellite swaths we could do

define xmean = ave(x+0*sat.2,t=1,t=124)

where "sat" (on file "2") is some gridded (time dependent) satellite measurement with lots of undefs.

You can use HDFView to get the information first, and then to set the
information in the control file. HDFView is free avaliable at HDF
offical website.

Subject: [gradsusr] pdef file works at v1.9b4 but not  at v2.0.a9
Message-ID: <40829B0E077C1145A6DE44D39B3830A91FFD68B0C9@nerckwmb1.ad.nerc.ac.uk>

Dear All,

I have a dataset that uses a pdef file and that I can use in GrADS v1.9b4 (in both SunOS and RH executables downloaded from the GrADS website), but which results in a segmentation fault at v2.0.a9 (and, from memory, at v2.0.a8) - again in various downloads. Looks like it might be a bug in GrADS...but of course most things turn out to be user error! Any ideas?

Vague notion: The pdef data file is big-endian (as declared in the pdef line of the ctl file) but
I'm using a little-endian machine. I wonder if v2.0.a9 can't cope with this mix?

Subject: [gradsusr] set negative values to zero
Message-ID: <CABzcqstV-9hAcC4KLR7BE2tnsu4pOsOU4YK4uQE3=2K5k-JZ9Q@mail.gmail.com>

Dear GrADS users,

I am using GrADS v2.0.a9 in Linux.

I am going to set negative values to zero at each grid point in NetCDF file.
I've been trying this using "if statements" in .gs file like below,
but it didn't work.

'open .ctl file'
 if (varname < 0.)
    varname = 0.
 endif

If you have any experience in GrADS for this, please let me know.

Thanks in advance,
Eugene

You can do this.

Message-ID: <1E8644A2BCBD5E4A9967E1E00D5D4C7301143E6FDCD0@NDMSSCC05.ndc.nasa.gov>

Hello:

I have a netcdf file with many variables
    float Q(time, lev, lat, lon) ;
        Q:units = "KG/KG" ;
    float SA1_VMR_inst(time, lev, lat, lon) ;
        SA1_VMR_inst:units = "VMR" ;
    float SOA_VMR_inst(time, lev, lat, lon) ;
        SOA_VMR_inst:units = "VMR" ;
    float T(time, lev, lat, lon) ;
        T:units = "K" ;
    float TOLUENE_VMR_inst(time, lev, lat, lon) ;
        TOLUENE_VMR_inst:units = "VMR" ;
    float TROPLEV(time, lat, lon) ;
        TROPLEV:units = "KM" ;
float U(time, lev, lat, lon) ;
        U:units = "M/S" ;
    float V(time, lev, lat, lon) ;
        V:units = "M/S" ;
    char current_mss(nchar) ;
        current_mss:long_name = "MSS pathname of this file" ;
    int date(time) ;
        date:long_name = "current date as 6 digit integer (YYMMDD)" ;
    int datesec(time) ;
        datesec:long_name = "seconds to complete current date" ;
        datesec:units = "s" ;
    int days(time) ;
        days:long_name = "elapsed simulation days for this case" ;
    char first_mss(nchar) ;
        first_mss:long_name = "MSS pathname of first file for this case"

I use the following script:

* B Vs -VTL
'reinit'
'sdfopen /Volumes/JWS/MOZART_OUTPUT/LARGE_DOMAIN/mozart4-20110721100736853957.nc<http://mozart4-20110721100736853957.nc>'

'c'
"set parea 1 10 1 7.5"
"set LON -30 59"
"set LAT -12 30"
"set LEV 1"
'set grads off'
'set gxout shaded'
"set rgb 24 255 120 120"
"set clevs 20 40 60 80 100 120 140 160 180 200 220 240"

'draw title 22 May 2006 MOZART L3\OzoneMixing Ratio (ppbv)'
'printim /Users/jonathanwsmith/MOZART/mozart_22may.gif'

For what ever reason I am only able to plot the one and three dimensional variable like days (1-D) or PS (3-D.  I am am unable to plot Q or SOA_VMR_inst which are 4-D?

What could be going wrong?

Jonathan,

This sounds familiar... GrADS may not be able to display both 3D and 4D 
fields if they are in the same netCDF file (don't know why)... One thing 
to try is to extract the 4D fields into a separate netCDF file (e.g. 
using "ncks" if you have it).

Hope this helps,
Chuck

Dear Douglas,

Please try to change

pdef 67420 1 file ...

to you real grid size

pdef ix jy file ...

where ix and jy are dimensions of your original curvilinear grid,
such that ix*jy=67420.
It must still work in version 1.9 and could work in versions 2 of GrADS.

Looks like it might be a bug in GrADS...but of course most things turn out to be user error! Any ideas?

Hi,
you can do like this also.
'open {your control file}'
'set gxout fgrid'
'd {any parameter in your control file}'

It will also work

Hi John,

thanks for your answer. I know how to redirect channels on the command 
line.
But how to decide IN the script, what should go to stderr and what to 
stdout, 'say' always put the output to stdout.
So in bash i would do echo "foobar" 1>&2 to get the foobar to the 
stderr, how can i do this in GrADS? Is there a way?

Best Regards,
Simon

Sergey,

Thanks for your answer. In fact I don't think your suggestion was the answer I needed, but it did cause me to look at the documentation again, at which point I got my answer!

My data are essentially a "vector" of land points and I use the pdef to scatter these across a lat-lon grid (very like the final example on the pdef documentation page). So the "native grid" really is 67420 x 1. The problem was that in the pdef data file (WFD_0p5deg_pdefData.gra in my example below), I had values of zero for the index (or offset) variable over the sea - i.e. the locations that I didn't have data for. These would have been better set to the missing data value. At v1.9.b4, the zeroes worked fine (and I was blissfully unaware that GrADS was struggling with different offset values for GRIB and non-GRIB files). At v2.0.a9 presumably GrADS notes that I don't have a GRIB file and tests the offsets; when it finds a zero it fails (rather dramatically with a core dump!).

So the answer was to make sure that my offset is set to the missing data value where I don't have data. Which sounds (and is) pretty obvious, but had worked for years with zero instead!

I have been using this style of pdef file for years and hadn't noticed that the online documentation for pdef now has various "WARNING" and other messages documenting issues with the offset (and that pdef FILE is now deprecated in favour of pdef GENERAL).

Thanks again,
Doug

Dear Douglas,

Please try to change

pdef 67420 1 file ...

to you real grid size

pdef ix jy file ...

where ix and jy are dimensions of your original curvilinear grid,
such that ix*jy=67420.
It must still work in version 1.9 and could work in versions 2 of GrADS.

Douglas,

The zero values for the mask in pdef file look to be normal.
But reading your netcdf require to know each dimension size
"as it is" in your file. When you provide description file (ctl)
grads ignore internal netcdf information for dimension
using yours instead. Then, for the input arrays allocation
"67420 1" is OK, but the real netcdf lat-lon grid size is necessary for
correct data input before the pdef mask  application.
Please run ncdump on you file and try "nx ny" instead.
Just it must help. Or, if you are ready to rebuild an interpolation
arrays, please create PDEF of GENERAL type that is better documented.

Once more, the problem is in reading not the pdef mask file, but
in reading from your netsdf file all 67420 values along the first (x or lon)
dimension with all other dimensions fixed! It crashes netcdf library
and then grads, I guess.

In Grads prior version 1.9 the pdef do not worked for netcdf files at all
due to this problem, but worked for binary files.
>From 1.9 it worked, but already required to use nx and ny
instead of "nx*ny 1" for FILE type pdefs in case of netcdf files,
except that your netsdf file really has
an internal structure with "67420*1" spatial grid.

Good luck to you!

Sergey

silently crashes. Nothing is written on both STDOUT or STDERR. The
only thing that I can get is that grads gives a return code 141 in the
shell after failing.

Can you tell me what this return code means? Do you have any idea why
my job can be run manually but not from cron?

Subject: [gradsusr] Missing variables in 3-d fwrite binary file
Message-ID: <4E2971D2.6050800@meridian-enviro.com>

Good morning.

I'm attempting to configure some post-processing subroutines for several 
parameters I find useful. For my pathfinder case, I am creating a binary 
file using "fwrite" to store four parameters. Each parameter varies in 
the horizontal plane, but not in the vertical (i.e. only one vertical 
level is computed). When I output a single timestep, I can open and 
retrieve the data file and the data display correctly. If I write each 
variable twice, once for each time step, I can retrieve the first time 
step, but not the second. At present I'm feeding commands into the 
command-line interpreter rather than executing a script. I've seen 
examples in the archives discussing varying the time dimension by way of 
a "while" loop. Since I'm entering the commands individually the result 
/should/ be the same as if run from a script.

I'm not sure where I'm making my mistake in the process, so any guidance 
would be appreciated.

Input data is the North American Mesoscale (NAM) 40 km model. I am 
computing values for "t 1" and "t 2" during this trial period.  The 
variables utilized in the process are "cpd", "isenps", "u", and "v". 
Command sequence is first, followed by the .ctl file. I use a homemade 
script file, "compute_cpd.gs", to conduct the necessary calculations. 
This script accepts three arguments, Theta surface (in Kelvin), grid 
skip, and working file number. compute_cpd.gs returns cpd, isenps, u, 
and v. In this case, "z" in NAM-2011072200.dat represents the "theta" 
level for the isentropic surface.

--- Command Listing ---
open NAM-2011072200.ctl
set t 1
run compute_cpd.gs 315 1 1

set fwrite ./cpd/NAM-2011072200.dat

I looked through the GrADS source code, specifically gscrpt.c file and the 'printf' function is used.

The 'printf' always goes to stdout.  Had it been fprintf(FILE *somefp,...) then maybe it could have been.

However, I don't think the original designers (aka Brian Doty) was concerned about writing to stderr.

Hi John,

thanks for your answer. I know how to redirect channels on the command line.
But how to decide IN the script, what should go to stderr and what to stdout, 'say' always put the output to stdout.
So in bash i would do echo "foobar" 1>&2 to get the foobar to the stderr, how can i do this in GrADS? Is there a way?

Best Regards,
Simon

There could be a number of reasons. Bernd's reply is true in that a cron script does not set a PATH and so by sourcing your profile or .bashrc files it will establish your environment. It is easier to put those PATH assignments in the cron script itself. Add the GrADS variables (GADDIR and GASCRP) as well to find the library scripts.

Second, the error code 141 means it is a SIGPIPE error. 141=128+13. 13 indicates a pipe error. 128 is the bash script error.

Third, it could be related to the resources on your machine itself could be the problem.

Can you give us your script?

Hi Teresa,

sorry for replying so late, i had some personal issues. well I have some
difficulties with this technique since I have statistically significant
values both negative and positive, so when i do set cmin or cmax, it will
block out the others. Is there a way to set it to absolute values?

With regards to scorr, I am of the understanding that grads correlates the
final spatial distribution of both and thus producing one value. I guess for
statistical significance one can use the values on statistics books, and
also consider the resolution of the image to obtain n

Regards,

James

Hello,

I have examined the environment of the calls on both my grads machine
and my remote machines. There are three machines involved in this: two
remote machines where WRF computations are run (these are located in
different data centers and have a slightly different setup) and my
grads machine where the output of the WRF computation is pushed and
then a script is started via ssh.

So the basic script on the remote machine looks like this:
- wait for new data from the forecast model
- scp the data to the grads machine
- ssh grads_machine image_generation_script.sh

The image_generation_script.sh running on the grads server is also quite easy:
- set up environment variables
- perl script to generate a grads script
- grads -b -l -c my_generated_script.gs

I have compared the environments on both the remote machines as the
script is run via cron, and the environment variables are exactly the
same on both machines. On the grads machine, I have also done this,
and the environment also matches there when being called from both
remote machines. There are two things that I don't get:
- on one remote machine everything is working fine, and the other one fails
- if I start the script on my failing remote machine manually,
everything works fine, but not when it gets executed by cron

Is there a way to get any additional output or debug information from
grads? Do you have any other hints what I could try?

Best regards and thank you for your help!

Jonas Kaufmann

That's fits my third guess that it fails on a busy machine.

What is the hardware, the operating system, the memory (vmstat,free), and the ulimit of your space  on both machines.

Subject: Re: [gradsusr] GrADS Return Code 141

Hello,

I have examined the environment of the calls on both my grads machine and my remote machines. There are three machines involved in this: two remote machines where WRF computations are run (these are located in different data centers and have a slightly different setup) and my grads machine where the output of the WRF computation is pushed and then a script is started via ssh.

So the basic script on the remote machine looks like this:
- wait for new data from the forecast model
- scp the data to the grads machine
- ssh grads_machine image_generation_script.sh

The image_generation_script.sh running on the grads server is also quite easy:
- set up environment variables
- perl script to generate a grads script
- grads -b -l -c my_generated_script.gs

I have compared the environments on both the remote machines as the script is run via cron, and the environment variables are exactly the same on both machines. On the grads machine, I have also done this, and the environment also matches there when being called from both remote machines. There are two things that I don't get:
- on one remote machine everything is working fine, and the other one fails
- if I start the script on my failing remote machine manually, everything works fine, but not when it gets executed by cron

Is there a way to get any additional output or debug information from grads? Do you have any other hints what I could try?

Best regards and thank you for your help!

Message-ID: <CAHBht21kN88RLVQ8u_+mG_ZRxgzKfHsO-jpXB=Y_LgSdhjuaGg@mail.gmail.com>

*Dear GrADS users,

I have downloaded synoptic monthly means analysis data from ECMWF for
specific humidity at 1000 pressure level both in netcdf and grib format
(This is the same data in grib & netcdf format for three months of 1989). I
encountered a bug or some issue in perl script (grib2ctl.pl) that generates
GrADS readable control file for the grib data set. I am attaching grib file
and control file made by grib2ctl.pl as well as index file generated by
gribmap. The bug is that synoptic monthly means data have 4 time steps (at
00, 06, 12, & 18) for each month but grib2ctl.pl makes 4 time steps in each
day instead of 4 time step in a month. When I opened the ctl file in GrADS,
it display some values and shows rest as all undefined values. I even
changed time in ctl manually and generate index again but the problem is yet
unresolved. Where is the issue? Does anyone already encountered the same
problem. Please see attached files for your satisfaction.

Mubashar,

Are you sure the data is what you expect? Does your grib file have 4 time steps x 30 some days in the month of interest? Or are you positive it is just those for time steps averaged for each day in the month?

Mason

Hello,

the machine itself was okay - however I have found the answer in the
mean time. In my original script running on my WRF server I tried to
capture the output of the remote ssh command for debugging using:
ssh grads_machine image_generation_script.sh & > logfile 2> errorfile

I changed this to (notice the brackets):
(ssh grads_machine image_generation_script.sh &) > logfile 2> errorfile

...and from this point on everything went fine - although I am not
sure why this failed at all...

Anyway, thank you for your help and for your hints on where to look further!

Best regards and have a nice weekend!

Jonas Kaufmann

Hi Kevin:

It looks like in your NAM-2011072200.ctl file you are defining one 
vertical level:

zdef 1 levels 315

but you then assign two levels to each variable:

cpd                   2 99 Condensation Pressure Deficit (mb)
isenps                2 99 Pressure (mb)
u                     2 99 Zonal component of wind (ms^-1)
v                     2 99 Meridional component of wind (ms^-1)

I think if you change the "2's" above with "1", or for surface you can 
have "0",
it should work ok.

Subject: [gradsusr] incorrect time steps
Message-ID: <1311354464.42717.YahooMailNeo@web31901.mail.mud.yahoo.com>

Hi,
I have used CDO operators to create monthly netCDF file from daily data. The timestamp of the resulting file when viewed in CDO is:

1989-01-31T00:00:00
1989-02-28T00:00:00
1989-03-31T00:00:00
1989-04-30T00:00:00
......
.....

But the timestep of the same file in grads is:

1989-01-31:0
1989:3:3:0

1989:3:31:0
1989:5:1:0
....
....

This is different and I guess is causing problem in time series plot etc. How can I overcome the problem?

I am using grads version 2.0.a7.oga.3 in Linux OS.

Any advice will be highly appreciated.

Hi Mason,

Yes of course it is synoptic monthly means at 00, 06, 12 and 18 UTC. plz
have a look on the attached netcdf, grib files of the same data set and see
the clear difference between netcdf and grib2ctl.pl generated control file.



Regards,

Mubashar

Hello
i am trying to plot muti images in the same panel ,i am trying to use the
panels.gsf .i wanna to usse it in command line mode
so how can i use the global variable (_vpg.p) in the panels.gsf to define
the number of plot i wanna to plot .
for example
*open plot.ctl*
*panels.gsf 2 2 *
*_vpg.1*
*d u*
*_vpg.2 *
*d v*
thanks in advance

Mubashar,

    The grib ctl file looks fine. If you want the 00Z jan, "set time  
00z1jan1989". 
If you want the 12Z feb mean, "set time 12Z1feb1989".  GrADS requires the
time variable to have fixed time steps so you will have undefined data 
for all but
the first day of the month.

Hai,

I want to plot surface current above sst. For this I am using Argo sst data
and
Oscar surface current data. The details of this files are given below:
----------------------------------------------------------------------------------------
ga-> q file 1
File 1 : 1x1 Monthly gridded climatology on Standard Levels
  Descriptor: Gr_clm_temp_lev_0_2000m.nc

  Type = Gridded
  Xsize = 360  Ysize = 180  Zsize = 27  Tsize = 12  Esize = 1
  Number of Variables = 1
     temp  27  t,z,y,x  argo temperature (degc)
ga-> q file 2
File 2 : OSCAR Surface current data climatology 2003-2010 averaged
  Descriptor: oscar2003_2010clim.ctl
  Binary: oscar2003_2010clim.bin
  Type = Gridded
  Xsize = 360  Ysize = 120  Zsize = 1  Tsize = 12  Esize = 1
  Number of Variables = 2
     u  1  99  zonal velocity component
     v  1  99  meridional velocity component
-------------------------------------------------------------------------------------------

I plotted the sst , but when I am trying to plot the surface current above
sst, I am getting
the following warning message.
--------------------------------------------------------------------------------------------

Sudev,

The problem (I think) is that your current time dimensions settings do not overlap with the times available in your file #2.

Your second file has 12 times but the line in the error message
"Grid limits of request:? X = 35 111? Y = 40 88? Z = 1 1? T = -119987 -119987? E = 1 1"
indicates that the time you have selected from the SST file is before the start of the surface current data (t=-119987).

You can override the current time dimension settings (i.e. choose a particular time) by using, e.g.
d u.2(t=1);v.2(t=1)
to plot the first time of surface current data. You can choose any of the 12 times available in this way.

Doug

Jim,

I thought those values represented the time step. After changing them to 
"1" as you suggested, the data are what I was expecting. My next step is 
creating multiple levels corresponding to numerous isentropic levels. 
For each level I add, I'll increment the "1"s to the number of vertical 
levels.

Many, many thanks for you suggestion.

Dear all
      I tried to write the grads out put values into a ascii file by using
the fprintf.gs script. I tried the following command

> set x 1 54 (since the .dat file has 54 longitude and 36 latitude points)
> set t 25
> fprintf  t2-273.15   T2-24hr.csv  %g, 54

but the file T2-24hr.csv  has only two rows of data instead of 36 rows of
data. What may be the error with this script or command.

waiting for your kind reply

thanking you
with regards

Subject: [gradsusr] Variable 'HFX' from ctl file
Message-ID: <CA+_3LvrzGiTY_nsK33FKTuX==uW6o0bVGQFEqj5nHS84yv8AqQ@mail.gmail.com>

Hi guys,

I have a question about the variable 'HFX' that from the ARWpost .ctl
file. The description reads 'upward heat flux at the surface', and I
wanted to know if this meant total heat flux or simply sensible heat
flux.

Any ideas are appreciated!

Dear all,

i have a problem with opening a file.
I use (GrADS) Version 2.0.a9 on Suse

ga-> sdfopen GKSS-2.nc
Scanning self-describing file:  GKSS-2.nc
gadsdf: Error parsing time_units for SDF file.

the format is as follows:
(from ncdump)

         double time(time) ;
                 time:units = "day as %Y%m%d.%f" ;
                 time:calendar = "proleptic_gregorian" ;
                 time:axis = "t" ;
                 time:long_name = "time" ;

So i think this is valid format? Can anyone tell my what is wrong?

Best Regards,
Simon

 time:units = "day as %Y%m%d.%f"   It does not follow GOARDS
conventions which is used in 'sdfopen' function. So you need to write
a control file to tell GrADS the dimensions and variables in the data
set. You have to use 'xdfopen' or 'open' commands to open the data
file.

Dear Yaqiang,

thank you for the information, where can i find the GrADS conventions to 
know which  format is ok,  and which not?
I'm very new to GrADS, so can you give me a source where i can find a 
example of a control file? I have no idea how to do that.

Best Regards,
Simon

inside a script you could redirect using unix shell
e.g.:
'!echo ERROR ON FILE >&2'

I've just tried and it seems to work

bye bye

Subject: [gradsusr] error with fprintf command (dipak sahu)
Message-ID: <CAMUironTPfwN=9SeKSFADRR66rsBz6GLk0P+nKUbf+h2CO9+PQ@mail.gmail.com>

hi Dipak,
 I think with the fprintf function u will have to set y values also. From
the script u sent

> set x 1 54 (since the .dat file has 54 longitude and 36 latitude points)
> set t 25
> fprintf  t2-273.15   T2-24hr.csv  %g, 54
u are varying x dimension at some constant time, what about y?? But then
also your output file should contain only one row of 54 values since by
default grads must have set latitude to the first value in the domain. Try
by giving some value to y dimension.

Bye
Roopa

Hi Dipak,

*
Look at the foll two lines
ga->* set x 1 72
*ga->* fprintf ts ts.csv %g, 72 0

I think you should give

set x 1 54
> set t 25
> fprintf  t2-273.15   T2-24hr.csv  %g, 54 0
try it and let me know or else if poss send me the data i will check.

Bye
Roopa

This is a bug that has been fixed for the next release. The problem  
was that the subroutime gxqdrgb() needed to be moved from gxhpng.c to  
gxX.c. It will compile as is if you enable the printim command, which  
needs zlib, libpng, libjpeg, and libgd. Also, you need to add -lrt to  
the list of libraries to link with, that will fix the undefined  
reference to clock_gettime. Please have a look at http://iges.org/grads/gadoc/supplibs.html

Subject: [gradsusr] in netcdf file unable to display 4-D variables
In-Reply-To: <4E28B83A.4000501@noaa.gov>

You did not include the ncdump output that shows the metadata for the  
coordinate axis "lev" -- it may have been insufficient. If that is the  
case, then GrADS won't recognize variables that use that coordinate  
axis. Furthermore, you need to include the version of GrADS you are  
using, since the sdfopen interface has changed over time and this  
information may be quite relevant. After you have sdfopen'ed your  
file, try a 'q file' and see if it has found a z-axis with levels that  
match the ncdump output. If not, then you will need to write a  
descriptor file, either a short version for the xdfopen command, or a  
complete one for the open command. The documentation is at http://iges.org/grads/gadoc/SDFdescriptorfile.html

Subject: [gradsusr] LFC calculation
Message-ID: <4E301AEA.7030108@meridian-enviro.com>

Meredith,

I ran into a similar problem while attempting to compute condensation 
pressure deficit (CPD). My solution was to derive an equation for my 
value of interest and then implement it in GrADS. Deriving the equation 
was the most difficult portion of this task. Once I had that in hand, I 
used several steps to bootstrap the solution in GrADS. For example, my 
CPD equation requires virtual temperature and the change in height by 
way of the hypsometric equation. For one step, I calculate the virtual 
temperature grid. In the next step I use the calculated virtual 
temperature grid in the hypsometric equation to find the change in 
height. For my way of thinking, a step-wise process, taking each piece 
in a small chunk, is easiest to comprehend during the testing phase. 
After you verify your solution works, you can refine the method to 
improve your processing efficiency.

In my experience, you can "define [var]=[eqn]" to create the appropriate 
gridded variable. If you have x and y varying (for a single time), 
you'll calculate the variable for each gridpoint in your domain or vary 
x, y, and t for multiple time steps in your domain.

Hope this helps.

Hi Everyone,

I'm looking to plot a contour plot of LFC height, similar to the graphic
on the SPC Mesoscale Analysis page, my control file does not output LFC
directly,  is there anyway I can calculate this in grads?

Thanks for your help.

Meredith

You may just need to set your time interval to something different. Try

set t 1 50
in grads command line

to see the temperature in kelvin for the first 50 timesteps. You should see
contour plots pop up really quickly, starting from the first timestep and
stop at the 50th timestep for your domain. I hope that works.

Estefan?a:

Another thing to check is your file names.  In the ctl file you specify:
*Eta_exp110km1960010100+%y4%m2%d2%h2.bin
*which means when/if you "set t 1", it will look for a file called:
*Eta_exp110km1960010100+1960010100.bin

*If you do not have such a file, you'll get all undefined values.  I suspect
that the first part of the file probably changes as well?  Or maybe you
have the data files in a subdirectory?

Turns out the subsetting *is* the culprit... changed it from the CONUS to
US/Canada/Alaska and it actually downloads (insignificantly) faster... I'll
try testing raw data downloads sometime too (especially since I can use
parallel connections without bogging down the NOMADS server). Oh, and I
implemented the staggered downloads and now have a lag of about 2-4 seconds
for the first map and 12-20 seconds for the last map (GrADS is really fast
at generating maps... at least when the right settings are used on printim).

Thanks,
Joey

Hi all,

I finally solved my problem by converting the time axis from absolute to 
relative with "cdo -r copy inputfile outputfile".

HB,

Here's an example of plotting vertically averaged wind streamlines for a
single timestep from a forecast model:

'set time 00z30jul2011'
'define u=ave(ugrdprs,lev=1000,lev=300)'
'define v=ave(vgrdprs,lev=1000,lev=300)'
'set gxout stream'
'd u;v'

Subject: [gradsusr] how to draw orography
Message-ID: <CAKDXP1JzEfcqJNa_AJXV5VirByHbc5tQj_n6ib_FdjeUabVu2Q@mail.gmail.com>

Hi you all!

Does anybody know how to draw the orography used in the NCEP/NCAR reanalysis
1 datasets using GRADS ?

I have downloaded teh file orog.spec.nc but I cannot think of how to use it.

Many thanks.

Subject: [gradsusr] how to display collected data when T varies
Message-ID: <BLU136-W297E5BB07055DAA09F82C1EA370@phx.gbl>


Hi All,
Have a set of WRF output data, post processed into GRADS data (de.ctl and de.dat). The data is for couple of days with time increment 3hrs. 
Want to plot out the average OLR along a slant line (cross section, say from 40E 10N to 70E 25N) with 10 degrees in latitude. We can do this easily if the averaging is along a straight line (e.g. ave(olr,lat=5,lat=15) for lon 40 70). 
Tried "collect" and "gr2stn". "collect" works for data varying in Z or T; I can collect the averaged values of OLR with varying T. However, "gr2stn" works only for varying Z, not T. 
Question: How do I display the collected data with varying T? It seems that I can't use "gr2stn". 
Thanks. 
Liping

Hi Eduardo.
You can download the topo data from this link:
http://users.ictp.it/~pubregcm/RegCM3/globedat.htm#part5
for display Topography in contour or shaded format just type these command
in GrADS terminal:
set lat x1 x2
set lon y1 y2
set gxout contour(or shaded)
d EXPR

Subject: [gradsusr] define a simple scalar
Message-ID: <4E3454C8.8000003@ucsd.edu>

Hello,

I'm having a problem with what I'm sure is a simple task.  I want to 
define a scalar to convert a slope (i.e. units/year) into a trend line 
over several years.  I'm using this to detrend a time series.   
Basically I just need to construct a simple scalar (i.e. variable = 1 2 
3 4 5...) or a variable that equals the year of each entry of my dataset 
(i.e. variable = 1991 1992 1993 1994 1995...) that I can multiply by my 
slope values.  I can use tloop to create the right dimensions (variable 
= 1 1 1 1 1...) but I can't seem to get the values to increase for each 
time step.

Imagine I could either create a datafile manually and read it in or 
somehow extract the year information from the existing dataset into a 
user defined variable.

Is there an equivalent of 'define variable(t=2) = 2'?  I know this 
syntax is wrong.

Any advice would be appreciated.

Lisa

set t 1
variable1 = const(kanto, 1, -a)
set t 2
variable2 = const(kanto, 2, -a)

where "kanto" is any variable in the file.

AFAIK there is no way to define different timesteps of the same variable in
different ways. A for loop can take care of the trouble involved with using
multiple variables.

Helloo,
          Which data you want to plot using stationgrads.  I know how to
plot rainfall data using station grads. If you want rainfall data to plot
then probably I can help. What you need is to have an ascii file of data.
Let me know your specific requirement.

Kindly send me one sample of your ascii file including latitude, longitude,
station name year, date , rainfall etc. Let me try and after that I will
send you the programs and required gs files and the procedures needed to
plot the file in grads. Best of luck.

Hi All,

I would to use NCEP/NCAR Wind Speed Data which is available at 2.5 x
2.5 degree for Trend analysis & correction factor. Initially, I would
be interested in undergoing ?two tasks :

1. would like to interpolate the WS data from 2.5x 2.5 degree to 1 x 1
degree using GrADS. I understand GrADS is the best tool for displaying
and interpolating the same. Can anybody help me how to do this, please
send me codes & conceptual help as well.

2. Secondly, ?I am using Window as Operating system and I need to
install the same in my System. I have tried quite often but was
unsuccessful.While installing, it always ask for cywgin ?platform it,
and error message is popped up showing .dll is missing. Please help my
in this regards and send a complete packet of setup files and
installation guide describing the various steps to be followed in
sequential manner.

Regards,

Zia

Try running GrADS in verbose mode to see what exactly is wrong.

Hi Dear GrADS users

How can I create TTF format of output maps instead of png and gif?
I am using GrADS in LINUX OS(ubuntu 10.4) and 2.0.a9 oga version

Dear all,

I would like to have your confirmation for this expression in grads:

Exponential: 'exp (expression)' is it true?

And how if I want to make something like:

(a+b)*(a+b) = (a+b)^2 is that true?
(a+b)*(a+b)*(a+b) = (a+b)^3 is that true?


Thank you,

Hi all,

You can also use CDO if you have Windows. In addition to what Saeed had
said, you can also :

cdo -r mergetime ifile1 ifile2 ifile3 ofile

depending on what you need.

Regards,

Serge

Dear all,

I found it, Thank you anyway.
For power, just 'pow(exp,yourpower)' where exp your expression and yourpower
the power you want.
So it becomes:
(a+b)*(a+b)*(a+b) = pow ((a+b),3)

Regards,

Serge

Message-ID: <06B0A85218E0A34EBBFFF4435CA4BAA403C8F691F3@sawsptahub01.saws.local>

I have tried to avoid the page (X,Y) boundary markings by using the attached script but the marks always appears. The IF STATEMENT  does not appear to do the trick; how do I make sure that the marks at the boundaries do not appear but the interior marks appear?
For instance,

1)      if('bcx'!='xx1'| 'bcx'!='xx2' | 'bcy'!='yy1' | 'bcy'!='yy2')
'draw mark 4 'bcx' 'bcy' .1'
else
'draw mark 0 'bcx' 'bcy' .1'
Endif
RESULT IN MARKINGS ANYWAY,




2)if('bcx'='xx1'| 'bcx'='xx2' | 'bcy'='yy1' | 'bcy'='yy2')
'draw mark 0 'bcx' 'bcy' .1'
else
'draw mark 4 'bcx' 'bcy' .1'
Endif
STILL RESULT IN THE MARKINGS, AND

 3) if('bcx'>'xx1'| 'bcx'<'xx2' | 'bcy'>'yy1' | 'bcy'<'yy2')
'draw mark 4 'bcx' 'bcy' .1'
Endif

MARKINGS STILL AT THE BOUNDARIES.

NOTE: For testing choose BCX=XX1,BCY=YY1 or BCX=XX1,BCY=YY2 or BCX=XX2, BCY=YY1, or BCX=XX2, BCY=YY2.

there is a conceputal error, let's understand the meaning of:

  if('bcx'!='xx1' ...

this logaical is always false, because 'bcx' is a string, 'xx1' is a
string and they are different


in your script appears:

  'draw mark 4 'bcx' 'bcy' .1'

then it is clear that bcx is a scalar (it has a value)
...

correct the logical expr in this way:

  if(bcx!=xx1 ...

hoping it helps
bye bye

Subject: [gradsusr] correlation map
Message-ID: <CAOXKaKD3cZXGvrLaPtg_PAp_PDaALUW+xtDW+MN8Ex_NsJ5Xyg@mail.gmail.com>

Hi

I have 20 year composite in which i have two variables (meridional and zonal
wind speeds). I'm using the NCEP/NCAR reanalysis data from 1989 to nov2008.
I need a (spatial) map of correlation coefficients for that period.

I've explored the functions tcorr and scorr, but none of them is suitable
for that. The tcorr function requires that the first variable is only a
function of time, which is not in my case.

Thanks is advance

Sushant

Hi all,

I was wondering if using fwrite to write a binary file if it is possible to
specify the format to avoid having it in stream. For example, the data be
written at a format like 8e10.3 to have a formatted file. How to do it?

thanks

Subject: [gradsusr] if... else..... endif syntax error in GRADS
Message-ID: <CAPFxStizChjZay3FmxZouRQQSi5cMuNzEVHqb5wxoY5_cVuGXg@mail.gmail.com>

Dear all,

My file contains 2 variables a and b. I have the following condition:

if a>b => c=b
if a<b => c=a

so: d=c/b

in my .gs file, I tried:

'!if (a> b)'
'c= b'
'!else'
'c= a'
'!endif'
'define d=c/b'

but it gives syntax error.

Then I tried to define the c like:

'!if (a> b)'
'define c= b'
'!else'
'define c= a'
'!endif'
'define d=c/b'

Again, syntax error.

ERROR:
sh: -c: line 1: syntax error: unexpected end of file
sh: -c: line 0: syntax error near unexpected token `else'
sh: -c: line 0: `else'
sh: endif: command not found


Thank you in advance,


Best regards,

Dear GRads Users,

I've scoured the mailing lists and been back and forward with ECWMF. I've two sample files from them (ECWMF GRIB v1) which I simply can not get translated properly. If anyone can offer some assistance I'd greatly appreciate it before I go and do a lot of installing of ECWMF software that may not be needed. ECWMF does not have their GRIB2 versions of this data.

I've attached both samples - they are supposed to be weekly anomalies of 2m temperature and precipitation.

A pilot project in Nicaragua on heavy rainfall and landslide early 
warning in near real time:
http://georiesgos-ca.ineter.gob.ni/lluvia/nesdis/gif/index.html

You have to place the cursor over the map to see a movie. The single GIF 
frames are made with Grads from the NESDIS Hydroestimator data and are 
then put together with ImageMagick to generate the animation. On the 
left you can select a region or country in the Central America-Caribbean 
area.

The system is capable to generate alert messages by email when strong 
rain occurs over a landslide prone area, e.g. volcanoes in Central America.

Subject: [gradsusr] Isentropic variables and ctl files
Message-ID: <CAK55UEfqP_CyoSQaf6rNjf-fsc1Jih7XXcn7ogu9PEKapT+EJQ@mail.gmail.com>

Hello, everyone.

I'm working with Bob Hart's isentropic field script. One of my goals is to
process guidance for several isentropic levels, store the variables in a
file (NetCDF is the method of choice, at present), then retrieve each of the
isentropic levels by way of the "set lev" command with each of the
isentropic surfaces listed in the .ctl file under "zdef 9 levels" as  "290
292 294 296 298 300 302 304 306". Is there a method or process to execute
the isentropic script several times for several isentropic surfaces and
store the output in a single variable? For testing I'm working with NAM
data.

Many thanks,

Kevin Huyck.

Are you keeping track of GDS servers? Or other "non-graphic" sites that
still have grads as a backend? For example, our "download tool" sites, e.g.,

Message-ID: <CAHCbKuNazS2GLtGGK+Lpw4-tgnRrRK7rc3_ov888qaPr44Mz4Q@mail.gmail.com>

Hello.
I am using GrADS version 2.0.a7.oga.3.  I have a long paleoclimate
timeseries going from 3800 years before present to 12300 years before
present.  When I plot a section of this time series (i.e. 3800 to 7000) the
x-axis labels appear normal (i.e. 3000 4000 5000 ...).  However, when I
attempt to plot the entire timeseries the x-axis labels disappear except for
a single label appearing at 4000.  Attached are screen shots showing the
situation.  Any suggestions on how to remedy this would be greatly
appreciated.

Thanks!

Best,
Max

Message-ID: <20110708150313.y5vi2zjzwc4gkgwc@cubmail.cc.columbia.edu>

Hi Gradusers,
I am trying to get a temporal correlation of two data sets that also  
vary in x and y. Just to give you some context, I am comparing model  
data to observed data over a 52 year span. I wrote a script that  
calculates point by point temporal correlation by use of the tcorr  
function, but it is unusable for me as it is very inefficent! Was  
wondering if anyone had a correlation script/ suggestions for me?
here is the script:

***function to plot a temporal correlation with a spatial loop
function correlation(arg)

startx=subwrd(arg,1)
endx=subwrd(arg,2)
starty=subwrd(arg,3)
endy=subwrd(arg,4)
startt=subwrd(arg,5)
endt=subwrd(arg,6)

say 'longitude = ' startx ' to ' endx
say 'latitude = ' starty ' to ' endy
say 'years = ' startt ' to ' endt

x=startx
while (x<= endx)
'set x ' x
y=starty
while (y <= endy)
'set y ' y
'set t ' startt
'd tcorr(prcp.1,prcp.2,t=' startt ',t=' endt ')'
y=y+1
endwhile
x=x+1
endwhile
exit

Gabriel,

Not sure if this will do what you want (may be more than you need), but 
here's an email posted to the Listserv by Mary-Jo Nath:

Hope this helps,

Hi Max,
Try this: set xrange t-first t-end
             set xlabs numbers that you want put in x axis(set xlabs 1 2 3 4
5 6 7  ...)

Dear all,

I am totally new with Grads and not very good at informatics. I have a bunch

Message-ID: <fcc6d2e76c24.4e18668f@fsu.edu>

Hey Everyone,

A while back I received some help with displaying WRF output in GrADS using ARWPost.  Thanks!  Now, I have a question about some of the fields.  When I display some fields, the look normal and as expected. But, others look odd.  I have attached an image of my 'w' field at 500 hPa.  Some other fields, such as the boundary layer height, also share this pattern.  Other fields, such as the 'u' and 'v' winds, look fine.  I was wondering if this looks like an error somewhere in my ARWPost run or an error in my WRF run?  Thanks an advance for any help!

You could try to comment "options byteswapped" in the ctl file.

If Yaqiang's idea doesn't work, I would try re-running ARWpost with fewer
variables.  I doubt you really need all of those variables, and if your .dat
file is too large, there may be a problem with how it displays data.  Also,
it appears your XDEF and YDEF lines could be simplified by putting
XDEF 210 LINEAR 0.0217
or something like that, since all of your levels appear to be equally
spaced.

Thanks Saeed.
Unfortunately, it seems the set xlabs and set vrange2 commands do not
operate on the x-axis when it represents time. Perhaps I need to edit how
time is defined in the .cdl file.

Best,
Max

Introducing InstantWeatherMaps.com, a new weather model website. The site
has a lag (from when the raw data appears on the NOMADS server) of 10-30
seconds, compared to around 90 seconds for the closest other free site (the
new beta NCEP site). I offer over 150 variables, including Kuchera-method
snowfall (otherwise only found on Earl Barker's site, which has a lag of
around 30-90 minutes). Nearly a half-million GFS model maps are on my server
at any given time. I would appreciate any suggestions as to future
enhancements I could make to my site.

Consider using anti-aliasing fonts and lines, e.g.,

     http://portal.nccs.nasa.gov/cgi-yotc/fp_wx.cgi

This is obtained by replacing printim with gxyat. Make sure to read the
documentation for a trick to reduce the size of the image files (pipe to
pngquant) , something that would be important for you with 1/2 million
plots. Notice that you will need the opengrads bundle for this,


http://opengrads.org/wiki/index.php?title=Installing_the_OpenGrADS_Bundle

Type

ga-> gxyat

for a manual page.

Thanks for the suggestion. I ran tests of gxyat vs printim and found that
gxyat outputs roughly 4 images per second, and printim outputs roughly 20
images per second (when set to GIF mode, which about 65% faster than PNG at
the expense of a roughly 15% larger file size). I will keep using printim
for the forseeable future, since output speed is paramount to my site's
operation. I do have another question, though, which I will ask in a
separate message.

Subject: [gradsusr] NOMADS download speeds
Message-ID: <CAJv4EQqs3FZN=DqHTgh_R+ivDHTwv9NfcipU_TSszgO=48LVpA@mail.gmail.com>

Is there any way to speed up downloads from the NOMADS server (
http://nomads.ncep.noaa.gov/cgi-bin/filter_gfs_hd.pl)? I currently run a
site that spends around 6-8 seconds per forecast hour generating maps.
Having said that, it is quite frustrating to see download times for 1 MB of
GRIB data exceed 10 seconds at times. I currently use 4 wget sessions in
parallel to handle the downloading, and I only sleep for 2 seconds instead
of 10 when polling the NOMADS server to check when the next file is
available, so as you can see I am very speed-oriented. Is there any way to
download faster, or is partial-downloading (downloading part of the GRIB
file, generating the relevant maps for the first part while the rest
downloads, then generating the maps for the rest) the fastest way of doing
this?

Subject: [gradsusr] Computation of thermodynamic Indices
Message-ID: <BLU152-w42402221CC2A51228FAB7F8A450@phx.gbl>


Dear All, 
This problem is not particularly pertaining to Grads but  I am still putting it across in anticipation of a possible help.


It goes like this, I want to compute all the Standard Indices  
( like Showalter, K, SWEAT, CAPE, CINE  etc)
from the Rs data of a station. 


I am able to compute only LCL and then the moist adiabat (using the conservation of MOIST static energy) 
and I have computed the LCL from the RS data and then constructed the moist adiabat of the parcel till 200hPa. Part of the output of moist adiabat looks like this, 

(I)
INPUT LCL

 P T Z
 871.0 294.6 312.0
 MOIST ADIABAT
 P Z T Q NO OF ITRN
 871.0 312.0 294.6 .1952E-01 .3476E+06 0
 870.0 322.0 294.5 .1950E-01 .3476E+06 39
 869.0 332.1 294.5 .1947E-01 .3476E+06 39
 868.0 342.1 294.4 .1945E-01 .3476E+06 40
 867.0 352.2 294.4 .1942E-01 .3476E+06 39
 866.0 362.2 294.4 .1940E-01 .3476E+06 39
 865.0 372.3 294.3 .1938E-01 .3476E+06 40
 864.0 382.4 294.3 .1935E-01 .3476E+06 39

"MOIST.DAT" 676 lines, 44480 characters

(II)
My RS data of a station is at an interval of 50hPa and looks like this (Ht, TT, Td, WS, WD at different levels)


1981 03 10 00 2 1026 20.6 16.8 155 02 1520 18.6 11.2 201 04 ^M
1981 03 10 00 3 2038 15.6 8.2 195 03 2584 12.4 3.8 079 02 
 3159 8.4 -5.3 105 04 3768 4.8 044 03 




Kindly help me reg the computation of CAPE and CINE after I construct the MOIST adiabat for a station.

Dear forum members,

I met a specific problem with GrADS plotting shape files.
The first time with Linux applications I met a problem when
all graphical KDE system is shut-down and rebooted,
like MS Window!
All and any do not saved results
of any applications in the running session are lost...
Please be careful if you will try to reproduce this behavior!

GrADS version is
Config: v2.0.a9 little-endian readline printim grib2 netcdf hdf4-sds
hdf5 opendap-grids,stn geotiff shapefile,
Linux workstations runs openSUSE 10.3 (X86-64),
kernel version 2.6.22.19-0.4-default

After downloading some shape files from the
http://www.diva-gis.org/Data,
namely "countries" from the Global level data
and South Korea administrative boundaries
from the Country level data,
I permanently have this problem if
run next sequence of commands.
I tested it with the Word Ocean Atlas 2005 netcdf
files:

d something
draw shp countries
draw shp KOR_adm0

... and nothing more on the screen,
the new graphical session starts.

As I believe that all shape files are just data,
there must be some problem with memory
operations in the GrADS, I guess.

Individual shape files are plotted without problem,
including both mentioned, as just shapes or as filled polygons.

Does somebody had similar problem and do it is possible
to avoid such surprises with these or other shape files?

Sincerely yours,
Sergey Varlamov

Dear Nagaraju,

Thank you for your answer but I've already found it. Below is the script:

if (a> b)
'define c= b'
else
'define c= a'
endif
'define d=c/b'

Anyway, the if expression in grads is not accompanied by then.

Regards,

Serge

Joey,

       My impression of the nomads server is that it is very fast.  
However, I have a very fast link to the internet and
the site is only 10 miles away.

      You are using the GFS which has 0.5 degree resolution (260K 
points) and you are using the filter program
which can create a regional subset.   If you are asking for a 5x5 grid, 
then your download speeds will be
slow.  After all you have to process 10K points for every point sent to 
you. 

     Another possibility is that you may have run afoul of some 
fair-usage filter.   Every site needs some protection
against denial-of-service attacks and poorly programmed web scripts.  
Anyways the nomads help desk is a more
appropriate source of information than the GrADS user forum.

Dear Sir
I installed GDS in MAC OS X  10.6.3.(intell duo)  The grads version is v2.0.a9.javaa version is 1.6.0_17.
The GDS work properly with the ctl file/binary.But when I access the station data, the error message come listed below. I found probably the same problem in the grads previous mailing list in http://gradsusr.org/pipermail/gradsusr/2008-September/007531.html.Unfortunately, there is not enough information on it. I attach three logs files (console.out, gds.log, tomcat.xxxx.log) for more detailed information.Could you tell me how to solve this problem?

Start by reading the documentation:

       http://grads.iges.org/grads/gadoc/SDFdescriptorfile.html

You likely need to create a DDF and use xdfopen.

I have two 2D model grids that have the same horizontal grid spacing and the
same domain width (so the X-coordinate is the same between the two) and the
same domain height, but different numbers of levels in the vertical.  I wish
to compare the values of some variables such as vertical motion between the
two model grids.  How do I do that?

Are the levels really different, or one file is a subset of the other? Say,
one has fewer mandatory levels. If the latter, use lats4d or write your own
simple script to subset the larger file to make it appear as the first. If
the levels are really different, you will need to perform a remapping from
one vertical grid to another. This remap algorithm can vary from a simple
linear interpolation in log-p to a conservative scheme that preserves
monotonicity, all depends on your application. I usually perform this
remapping outside grads.

No, they're truly different in the sense that probably none of the levels
perfectly match up.  What algorithms do you know of?

Subject: [gradsusr] Problem with running sdfopen in windows batch mode
Message-ID: <CAG1cdGN6Qr1kiB-5EV_N3yPa7XyLzfaNgdE1O2g5jGqRVHWd6A@mail.gmail.com>

Dear all,

I'm using grads 2.0.a9.oga.1 installed in the c:\ drive of  Windows XP. I
wrote a batch script(.bat) to generate graphical outputs from
http://nomads.ncep.noaa.gov:9090.
The script works if it is   placed in any folder in the C:\ drive but fails
when it is  run from a pendrive, external drive , d:\ drive etc. Among the
content of the script is:  grads -blc "run script.gs"

The following messages were displayed on the execution of the script from an
external drive:

Jeff and Yaqiang,

Thanks for the ideas.  Unfortunately, I still haven't found a solution.  I have figured out a little more about the problem, I think.  It appears that it is the "standard" variables that look odd.  If I display the umet and vmet diagnostic variables, they look great.  But, if I display the standard U and V variables, they look just like W did.  

As you suspected Jeff, I don't need many variables, actually only the U,V, and W wind components.  But, even when just running ARWpost with the 'basic' fields option the variables look crazy.  Any more ideas would be greatly appreciated!

Thanks,
Nick

The netCDF data output from WRF are not follow COARDS or CF
conventions, so the data can't be read directly by many popular
meteorological softwares, including GrADS (I mean with sdfopen
method). I don't understand why WRF group made their data different. I
have no experience on ARWpost tool, but I know something of the netCDF
data format used in WRF, which is defined as 'WRF_OUT' conventions in
MeteoInfo software. So you can try to graph the data using MeteoInfo
temporally before you find a better sollution of it. You could only
use MeteoInfo in Windows system for netCDF data, although it could be
used in Linux for other data formats under the support of mono.

Nick,
Try viewing the raw netCDF output using ncview or use ncks to output the
actual coordinate values of some of the variables so that you can see them.
If the data looks bad when viewing the raw netCDF output, then something
went wrong in your model and ARWpost has nothing to do with it.  If it looks
clean, then it's something with ARWpost.  Let me know what you find out.

First, make sure you have a version of GrADS that supports reading HDF-EOS5 grid files (2.0.a7 or higher).
Below is a sample GrADS control (.ctl) file that will let you read an OMI SO2 level-3 gridded HDF-EOS5 data file:

DSET  OMI-Aura_L3-OMSO2e_2004m1001_v003-2011m0526t144250.he5
DTYPE hdf5_grid

ENDVARS


Note the group paths to the data field variables must be specified in full, and any spaces converted to tilda (~) characters.

You can rename the OMSO2e data files by removing the production date/time from the version (stuff after v003), then you would have 
a file name like OMI-Aura_L3-OMSO2e_2004m1001_v003.he5. With this you could modify the DSET (and add OPTIONS) to the .ctl file

DSET  ^OMI-Aura_L3-OMSO2e_%ym%m%d_v003.he5
OPTIONS template

and then you could read in multiple files for a range of dates (remember to also adjust the TDEF range).

Hi everybody,
I would be grateful to somebody who can clarify the foll point.
I want to check the rainfall output from a particular WRF simulation. Is the
total rain a sum of rainc and rainnc??. if cumulus scheme is not activated
then rainc = 0, so total rain = rainnc.

thanks in advance

Warm regards,
Roopa

what's the name of the precipitation variable you are using?  RAINC is
convective scheme precip, RAINNC is microphysical.  If you sum them, then
you get total precip.

See http://cookbooks.opengrads.org/index.php?title=Recipe-013:_Gridding_and_Plotting_Station_Data
and http://www.iges.org/grads/gadoc/aboutstationdata.html
and http://www.iges.org/grads/gadoc/usingstationdata.html

I see that your precipitation data sometimes is followed by a comma and another value. You should clean that up first.

For more insight from GrADS users, Google using the phrase 'station data site:gradsusr.org'

Message-ID: <979990096.135125.1310756439268.JavaMail.root@mailhub017.itcs.purdue.edu>

Hi, 

I'm trying to plot a timeseries of wind barbs of both WRF output and collected observations.  I'd like to plot WRF wind barbs first, then overlay observation data as wind barbs also.  However, my wrf data is gridded data and my observation data is reading into GrADS based on the 'x' coordinate.  Therefore for the obs data, I must use "set x " to pick out a time range.

Thanks,

Dear Grads Community,
  I'm new to GRADs, and I'm trying to get it started up on a Mac. I'm trying
to work through the tutorial to start with. I can either not properly
download the practice files, or I can't properly get my version of GRADs to
locate these files. Any suggestions?
Thanks so much,

If you mean the model.ctl, model.gmp, model.grb files, I usually put them in their own directory, like ~/grads/tutorial, chdir to that directory, and THEN start up grads.  Then you need to make sure that (1) you can find the grads executable and (2) you can find the other grads files, like the fonts and maps.

For #1, you can either (a) add the location of the grads executable to your $PATH variable, (b) set up an alias with the full path of your executable or (c) just type in the whole path of the executable (ugh).  In my case, I have it in my PATH, which includes /Users/clynnes/bin:

~/grads/tutorial>which grads
/Users/clynnes/bin/grads

For #2, make sure you have your GADDIR environment variable set to the directory where you installed the fonts and maps. On my Mac, for instance:

~/grads/tutorial>echo $GADDIR
/Users/clynnes/etc/grads
~/grads/tutorial>ls $GADDIR
dat		font3.dat	lomap.dat	nmap.dat
font0.dat	font4.dat	lowres		stroke.dat
font1.dat	font5.dat	mres		udunits.dat
font2.dat	hires		newmap		worldmap
~/grads/tutorial>

If you have installed the opengrads bundle, the sample file is included. Try
this:

Message-ID: <EF993BF88A0DA241AA5B306C9D22DDF753FF3FDF@it-kodiak.sooner.net.ou.edu>

Hello Grads community,

I can see from the tutorial that one can open several different case files in grads(file1, file2 etc) and average the data from these files for subsequent display. Is there an advanced option that would allow me to specify the domain for each case and then average them? I was hoping to use this function to easily complete an average of 25 cases or so but relative to some specific type of event, which requires different domain centering for each case prior to averaging.

The ave() functions allows you to make averages over a (x,y,z,t,e)
hypercube. Because undef values are skipped, you can have averages over very
irregular domains, provided an appropriate mask can be derived either
through an expression or by reading it from a file.  For example, to make a
time average along satellite swaths we could do

define xmean = ave(x+0*sat.2,t=1,t=124)

where "sat" (on file "2") is some gridded (time dependent) satellite
measurement with lots of undefs.

Is it possible to plot a map, without using any parameters? that is simply
getting the outline of the coastlines for the region?

And possibly even draw a few dots or crosses at particular locations

Dear gradsusers,

i invoke a gradsscript from bash and in case that the script can not 
open a file past to it, i want to give a return code back to the 
bashscript so that it knows, that the gradsscript could not open the file.
I have no idea how to do this. For subfunctions in grads i can use 
return but it seems not to work with the main function.
To exit early on i have to use quit it seems but with quit i can not 
give a return code.

I hope someone have a idea.

Best Regards,
Simon

If you are running GrADS in batch mode you can re-direct output as follows

grads -lbc 'run somescript.gs' 2> say.err 1>&2

In interactive mode there is no output to the screen it simply goes to the file.

Does that answer your question?

To plot a map with no parameters, first open any file with any parameters
(even the sample file will work). Then do this:

set clevs 0
set ccols 0 0
d param

where param is a valid parameter in that file.

You need to change DSET to:

DSET ^OMI-Aura_L3-OMSO2e_%y4m%m2%d2_v003.he5

and make sure the files are actually named something like:

OMI-Aura_L3-OMSO2e_2004m1001_v003.he5

What I like to do is keep the original files as downloaded from the archive, 
and then set up symbolic links with those types of names above. You can write 
a short Unix shell script to do this:

for file in OMI-Aura_L3-OMSO2e*.he5
do
  ln -s $file `echo $file | cut -c1-33`".he5"
done

I would also set TDEF to:

TDEF  3014 linear 01oct2004 1dy

and then you'll be able to read any of the files through the end of 2012, also 
the first day for OMI data is Oct. 1, 2004 (launch was July 15, 2004).

the 'draw map' command will also do it, but it won't plot any lat/lon lines
or coordinates since it won't have any actual map data to go off of (but it
will give you geo-political boundaries just fine)

Sushant and Diallo,

I found a confusing comment in the maxwind.gs and maxwind2.gs scripts 
referring to "plotting track of hurricane center" (not sure, but 
possibly left over from code copied from another script?), and changed 
the comment to "plotting location of max wind". Please find attached 
updated GrADS scripts maxwind.gs, maxwind2.gs.

Sorry for this confusion,
Chuck

Hello Arlindo,

I need to set a different domain center for each of the time periods in the ave function, like say 1 through 124 in your example. As such, the display would then become geographically irrelevant, asides from attaining a since of scale.

Hello Grads community,

I can see from the tutorial that one can open several different case files in grads(file1, file2 etc) and average the data from these files for subsequent display. Is there an advanced option that would allow me to specify the domain for each case and then average them? I was hoping to use this function to easily complete an average of 25 cases or so but relative to some specific type of event, which requires different domain centering for each case prior to averaging.


The ave() functions allows you to make averages over a (x,y,z,t,e) hypercube. Because undef values are skipped, you can have averages over very irregular domains, provided an appropriate mask can be derived either through an expression or by reading it from a file.  For example, to make a time average along satellite swaths we could do

define xmean = ave(x+0*sat.2,t=1,t=124)

where "sat" (on file "2") is some gridded (time dependent) satellite measurement with lots of undefs.

You can use HDFView to get the information first, and then to set the
information in the control file. HDFView is free avaliable at HDF
offical website.

Subject: [gradsusr] pdef file works at v1.9b4 but not  at v2.0.a9
Message-ID: <40829B0E077C1145A6DE44D39B3830A91FFD68B0C9@nerckwmb1.ad.nerc.ac.uk>

Dear All,

I have a dataset that uses a pdef file and that I can use in GrADS v1.9b4 (in both SunOS and RH executables downloaded from the GrADS website), but which results in a segmentation fault at v2.0.a9 (and, from memory, at v2.0.a8) - again in various downloads. Looks like it might be a bug in GrADS...but of course most things turn out to be user error! Any ideas?

At v2.0.a9:

-------------------------------------------------------------

Vague notion: The pdef data file is big-endian (as declared in the pdef line of the ctl file) but
I'm using a little-endian machine. I wonder if v2.0.a9 can't cope with this mix?


Cheers,
Doug

Subject: [gradsusr] set negative values to zero
Message-ID: <CABzcqstV-9hAcC4KLR7BE2tnsu4pOsOU4YK4uQE3=2K5k-JZ9Q@mail.gmail.com>

Dear GrADS users,

I am using GrADS v2.0.a9 in Linux.

I am going to set negative values to zero at each grid point in NetCDF file.
I've been trying this using "if statements" in .gs file like below,
but it didn't work.

'open .ctl file'
 if (varname < 0.)
    varname = 0.
 endif

If you have any experience in GrADS for this, please let me know.

Thanks in advance,
Eugene

You can do this.

For what ever reason I am only able to plot the one and three dimensional variable like days (1-D) or PS (3-D.  I am am unable to plot Q or SOA_VMR_inst which are 4-D?

What could be going wrong?

Jonathan,

This sounds familiar... GrADS may not be able to display both 3D and 4D 
fields if they are in the same netCDF file (don't know why)... One thing 
to try is to extract the 4D fields into a separate netCDF file (e.g. 
using "ncks" if you have it).

Hope this helps,
Chuck

Dear Douglas,

Please try to change

pdef 67420 1 file ...

to you real grid size

pdef ix jy file ...

where ix and jy are dimensions of your original curvilinear grid,
such that ix*jy=67420.
It must still work in version 1.9 and could work in versions 2 of GrADS.

Hi,
you can do like this also.
'open {your control file}'
'set gxout fgrid'
'd {any parameter in your control file}'

It will also work

Hi John,

thanks for your answer. I know how to redirect channels on the command 
line.
But how to decide IN the script, what should go to stderr and what to 
stdout, 'say' always put the output to stdout.
So in bash i would do echo "foobar" 1>&2 to get the foobar to the 
stderr, how can i do this in GrADS? Is there a way?

Best Regards,
Simon

Sergey,

Thanks for your answer. In fact I don't think your suggestion was the answer I needed, but it did cause me to look at the documentation again, at which point I got my answer!

My data are essentially a "vector" of land points and I use the pdef to scatter these across a lat-lon grid (very like the final example on the pdef documentation page). So the "native grid" really is 67420 x 1. The problem was that in the pdef data file (WFD_0p5deg_pdefData.gra in my example below), I had values of zero for the index (or offset) variable over the sea - i.e. the locations that I didn't have data for. These would have been better set to the missing data value. At v1.9.b4, the zeroes worked fine (and I was blissfully unaware that GrADS was struggling with different offset values for GRIB and non-GRIB files). At v2.0.a9 presumably GrADS notes that I don't have a GRIB file and tests the offsets; when it finds a zero it fails (rather dramatically with a core dump!).

So the answer was to make sure that my offset is set to the missing data value where I don't have data. Which sounds (and is) pretty obvious, but had worked for years with zero instead!

I have been using this style of pdef file for years and hadn't noticed that the online documentation for pdef now has various "WARNING" and other messages documenting issues with the offset (and that pdef FILE is now deprecated in favour of pdef GENERAL).

Thanks again,
Doug

Douglas,

The zero values for the mask in pdef file look to be normal.
But reading your netcdf require to know each dimension size
"as it is" in your file. When you provide description file (ctl)
grads ignore internal netcdf information for dimension
using yours instead. Then, for the input arrays allocation
"67420 1" is OK, but the real netcdf lat-lon grid size is necessary for
correct data input before the pdef mask  application.
Please run ncdump on you file and try "nx ny" instead.
Just it must help. Or, if you are ready to rebuild an interpolation
arrays, please create PDEF of GENERAL type that is better documented.

Once more, the problem is in reading not the pdef mask file, but
in reading from your netsdf file all 67420 values along the first (x or lon)
dimension with all other dimensions fixed! It crashes netcdf library
and then grads, I guess.

In Grads prior version 1.9 the pdef do not worked for netcdf files at all
due to this problem, but worked for binary files.
>From 1.9 it worked, but already required to use nx and ny
instead of "nx*ny 1" for FILE type pdefs in case of netcdf files,
except that your netsdf file really has
an internal structure with "67420*1" spatial grid.

Good luck to you!

So the "native grid" really is 67420 x 1. The problem was that in the pdef data file (WFD_0p5deg_pdefData.gra in my example below), I had values of zero for the index (or offset) variable over the sea - i.e. the locations that I didn't have data for. These would have been better set to the missing data value. At v1.9.b4, the zeroes worked fine (and I was blissfully unaware that GrADS was struggling with different offset values for GRIB and non-GRIB files). At v2.0.a9 presumably GrADS notes that I don't have a GRIB file and tests the offsets; when it finds a zero it fails (rather dramatically with a core dump!).

Subject: [gradsusr] GrADS Return Code 141
Message-ID: <CAMaBtSkkFVKiejO3uLJm5eVJON1n3+MqfSLb2od+tYSRTyCkaw@mail.gmail.com>

Hello,

in my setup I am running into a strange problem right now. I am
calling a shell script containing a call to grads from a remote
server. When I invoke my shell script manually from the remote server,
everything is working fine - however when running through cron, grads
silently crashes. Nothing is written on both STDOUT or STDERR. The
only thing that I can get is that grads gives a return code 141 in the
shell after failing.

Can you tell me what this return code means? Do you have any idea why
my job can be run manually but not from cron?

Best regards,
Jonas Kaufmann

Subject: [gradsusr] Missing variables in 3-d fwrite binary file
Message-ID: <4E2971D2.6050800@meridian-enviro.com>

Good morning.

I'm attempting to configure some post-processing subroutines for several 
parameters I find useful. For my pathfinder case, I am creating a binary 
file using "fwrite" to store four parameters. Each parameter varies in 
the horizontal plane, but not in the vertical (i.e. only one vertical 
level is computed). When I output a single timestep, I can open and 
retrieve the data file and the data display correctly. If I write each 
variable twice, once for each time step, I can retrieve the first time 
step, but not the second. At present I'm feeding commands into the 
command-line interpreter rather than executing a script. I've seen 
examples in the archives discussing varying the time dimension by way of 
a "while" loop. Since I'm entering the commands individually the result 
/should/ be the same as if run from a script.

I'm not sure where I'm making my mistake in the process, so any guidance 
would be appreciated.

Input data is the North American Mesoscale (NAM) 40 km model. I am 
computing values for "t 1" and "t 2" during this trial period.  The 
variables utilized in the process are "cpd", "isenps", "u", and "v". 
Command sequence is first, followed by the .ctl file. I use a homemade 
script file, "compute_cpd.gs", to conduct the necessary calculations. 
This script accepts three arguments, Theta surface (in Kelvin), grid 
skip, and working file number. compute_cpd.gs returns cpd, isenps, u, 
and v. In this case, "z" in NAM-2011072200.dat represents the "theta" 
level for the isentropic surface.

--- Command Listing ---
open NAM-2011072200.ctl

I looked through the GrADS source code, specifically gscrpt.c file and the 'printf' function is used.

The 'printf' always goes to stdout.  Had it been fprintf(FILE *somefp,...) then maybe it could have been.

However, I don't think the original designers (aka Brian Doty) was concerned about writing to stderr.

Hi John,

thanks for your answer. I know how to redirect channels on the command line.
But how to decide IN the script, what should go to stderr and what to stdout, 'say' always put the output to stdout.
So in bash i would do echo "foobar" 1>&2 to get the foobar to the stderr, how can i do this in GrADS? Is there a way?

Simon

There could be a number of reasons. Bernd's reply is true in that a cron script does not set a PATH and so by sourcing your profile or .bashrc files it will establish your environment. It is easier to put those PATH assignments in the cron script itself. Add the GrADS variables (GADDIR and GASCRP) as well to find the library scripts.

Second, the error code 141 means it is a SIGPIPE error. 141=128+13. 13 indicates a pipe error. 128 is the bash script error.

Third, it could be related to the resources on your machine itself could be the problem.

Can you give us your script?

Normalerweise liegt das an nicht gesetzten Umgebungsvariablen.

Einfach im Script oben nochmal

Subject: [gradsusr] GrADS Return Code 141

Hello,

in my setup I am running into a strange problem right now. I am calling a shell script containing a call to grads from a remote server. When I invoke my shell script manually from the remote server, everything is working fine - however when running through cron, grads silently crashes. Nothing is written on both STDOUT or STDERR. The only thing that I can get is that grads gives a return code 141 in the shell after failing.

Can you tell me what this return code means? Do you have any idea why my job can be run manually but not from cron?

Best regards,
Jonas Kaufmann

Hi Teresa,

sorry for replying so late, i had some personal issues. well I have some
difficulties with this technique since I have statistically significant
values both negative and positive, so when i do set cmin or cmax, it will
block out the others. Is there a way to set it to absolute values?

With regards to scorr, I am of the understanding that grads correlates the
final spatial distribution of both and thus producing one value. I guess for
statistical significance one can use the values on statistics books, and
also consider the resolution of the image to obtain n

Regards,

James

Hello,

I have examined the environment of the calls on both my grads machine
and my remote machines. There are three machines involved in this: two
remote machines where WRF computations are run (these are located in
different data centers and have a slightly different setup) and my
grads machine where the output of the WRF computation is pushed and
then a script is started via ssh.

So the basic script on the remote machine looks like this:
- wait for new data from the forecast model
- scp the data to the grads machine
- ssh grads_machine image_generation_script.sh

The image_generation_script.sh running on the grads server is also quite easy:
- set up environment variables
- perl script to generate a grads script
- grads -b -l -c my_generated_script.gs

I have compared the environments on both the remote machines as the
script is run via cron, and the environment variables are exactly the
same on both machines. On the grads machine, I have also done this,
and the environment also matches there when being called from both
remote machines. There are two things that I don't get:
- on one remote machine everything is working fine, and the other one fails
- if I start the script on my failing remote machine manually,
everything works fine, but not when it gets executed by cron

Is there a way to get any additional output or debug information from
grads? Do you have any other hints what I could try?

Best regards and thank you for your help!

That's fits my third guess that it fails on a busy machine.

What is the hardware, the operating system, the memory (vmstat,free), and the ulimit of your space  on both machines.

*Dear GrADS users,

I have downloaded synoptic monthly means analysis data from ECMWF for
specific humidity at 1000 pressure level both in netcdf and grib format
(This is the same data in grib & netcdf format for three months of 1989). I
encountered a bug or some issue in perl script (grib2ctl.pl) that generates
GrADS readable control file for the grib data set. I am attaching grib file
and control file made by grib2ctl.pl as well as index file generated by
gribmap. The bug is that synoptic monthly means data have 4 time steps (at
00, 06, 12, & 18) for each month but grib2ctl.pl makes 4 time steps in each
day instead of 4 time step in a month. When I opened the ctl file in GrADS,
it display some values and shows rest as all undefined values. I even
changed time in ctl manually and generate index again but the problem is yet
unresolved. Where is the issue? Does anyone already encountered the same
problem. Please see attached files for your satisfaction.

Mubashar,

Are you sure the data is what you expect? Does your grib file have 4 time steps x 30 some days in the month of interest? Or are you positive it is just those for time steps averaged for each day in the month?

When I opened the ctl file in GrADS, it display some values and shows rest as all undefined values. I even changed time in ctl manually and generate index again but the problem is yet unresolved. Where is the issue? Does anyone already encountered the same problem. Please see attached files for your satisfaction.

Hello,

the machine itself was okay - however I have found the answer in the
mean time. In my original script running on my WRF server I tried to
capture the output of the remote ssh command for debugging using:
ssh grads_machine image_generation_script.sh & > logfile 2> errorfile

I changed this to (notice the brackets):
(ssh grads_machine image_generation_script.sh &) > logfile 2> errorfile

...and from this point on everything went fine - although I am not
sure why this failed at all...

Anyway, thank you for your help and for your hints on where to look further!

Best regards and have a nice weekend!

Jonas Kaufmann

Hi Kevin:

It looks like in your NAM-2011072200.ctl file you are defining one 
vertical level:

zdef 1 levels 315

but you then assign two levels to each variable:

cpd                   2 99 Condensation Pressure Deficit (mb)
isenps                2 99 Pressure (mb)
u                     2 99 Zonal component of wind (ms^-1)
v                     2 99 Meridional component of wind (ms^-1)

I think if you change the "2's" above with "1", or for surface you can 
have "0",
it should work ok.

Subject: [gradsusr] incorrect time steps
Message-ID: <1311354464.42717.YahooMailNeo@web31901.mail.mud.yahoo.com>

Hi,
I have used CDO operators to create monthly netCDF file from daily data. The timestamp of the resulting file when viewed in CDO is:

1989-01-31T00:00:00
1989-02-28T00:00:00
1989-03-31T00:00:00
1989-04-30T00:00:00
......
.....

But the timestep of the same file in grads is:

1989-01-31:0
1989:3:3:0

1989:3:31:0
1989:5:1:0
....
....

This is different and I guess is causing problem in time series plot etc. How can I overcome the problem?

I am using grads version 2.0.a7.oga.3 in Linux OS.

Any advice will be highly appreciated.

Hi Mason,

Yes of course it is synoptic monthly means at 00, 06, 12 and 18 UTC. plz
have a look on the attached netcdf, grib files of the same data set and see
the clear difference between netcdf and grib2ctl.pl generated control file.

Hello
i am trying to plot muti images in the same panel ,i am trying to use the
panels.gsf .i wanna to usse it in command line mode
so how can i use the global variable (_vpg.p) in the panels.gsf to define
the number of plot i wanna to plot .
for example
*open plot.ctl*
*panels.gsf 2 2 *
*_vpg.1*
*d u*
*_vpg.2 *
*d v*
thanks in advance

Mubashar,

    The grib ctl file looks fine. If you want the 00Z jan, "set time  
00z1jan1989". 
If you want the 12Z feb mean, "set time 12Z1feb1989".  GrADS requires the
time variable to have fixed time steps so you will have undefined data 
for all but
the first day of the month.

Hai,

I want to plot surface current above sst. For this I am using Argo sst data
and
Oscar surface current data. The details of this files are given below:
----------------------------------------------------------------------------------------
ga-> q file 1
File 1 : 1x1 Monthly gridded climatology on Standard Levels
  Descriptor: Gr_clm_temp_lev_0_2000m.nc

  Xsize = 360  Ysize = 180  Zsize = 27  Tsize = 12  Esize = 1
  Number of Variables = 1
     temp  27  t,z,y,x  argo temperature (degc)
ga-> q file 2
File 2 : OSCAR Surface current data climatology 2003-2010 averaged
  Descriptor: oscar2003_2010clim.ctl
  Binary: oscar2003_2010clim.bin
  Type = Gridded
  Xsize = 360  Ysize = 120  Zsize = 1  Tsize = 12  Esize = 1
  Number of Variables = 2
     u  1  99  zonal velocity component
     v  1  99  meridional velocity component
-------------------------------------------------------------------------------------------

I plotted the sst , but when I am trying to plot the surface current above
sst, I am getting
the following warning message.
--------------------------------------------------------------------------------------------
........................................

Sudev,

The problem (I think) is that your current time dimensions settings do not overlap with the times available in your file #2.

Your second file has 12 times but the line in the error message
"Grid limits of request:? X = 35 111? Y = 40 88? Z = 1 1? T = -119987 -119987? E = 1 1"
indicates that the time you have selected from the SST file is before the start of the surface current data (t=-119987).

You can override the current time dimension settings (i.e. choose a particular time) by using, e.g.
d u.2(t=1);v.2(t=1)
to plot the first time of surface current data. You can choose any of the 12 times available in this way.

Doug

Jim,

I thought those values represented the time step. After changing them to 
"1" as you suggested, the data are what I was expecting. My next step is 
creating multiple levels corresponding to numerous isentropic levels. 
For each level I add, I'll increment the "1"s to the number of vertical 
levels.

Many, many thanks for you suggestion.

Dear all
      I tried to write the grads out put values into a ascii file by using
the fprintf.gs script. I tried the following command

> set x 1 54 (since the .dat file has 54 longitude and 36 latitude points)
> set t 25
> fprintf  t2-273.15   T2-24hr.csv  %g, 54

but the file T2-24hr.csv  has only two rows of data instead of 36 rows of
data. What may be the error with this script or command.

waiting for your kind reply

thanking you
with regards
Dipak Sahu

Hi guys,

I have a question about the variable 'HFX' that from the ARWpost .ctl
file. The description reads 'upward heat flux at the surface', and I
wanted to know if this meant total heat flux or simply sensible heat
flux.

Any ideas are appreciated!

Dear all,

i have a problem with opening a file.
I use (GrADS) Version 2.0.a9 on Suse

ga-> sdfopen GKSS-2.nc
Scanning self-describing file:  GKSS-2.nc
gadsdf: Error parsing time_units for SDF file.

the format is as follows:
(from ncdump)

         double time(time) ;
                 time:units = "day as %Y%m%d.%f" ;
                 time:calendar = "proleptic_gregorian" ;
                 time:axis = "t" ;
                 time:long_name = "time" ;

So i think this is valid format? Can anyone tell my what is wrong?

Best Regards,
Simon

 time:units = "day as %Y%m%d.%f"   It does not follow GOARDS
conventions which is used in 'sdfopen' function. So you need to write
a control file to tell GrADS the dimensions and variables in the data
set. You have to use 'xdfopen' or 'open' commands to open the data
file.

Dear Yaqiang,

thank you for the information, where can i find the GrADS conventions to 
know which  format is ok,  and which not?
I'm very new to GrADS, so can you give me a source where i can find a 
example of a control file? I have no idea how to do that.

Best Regards,
Simon

inside a script you could redirect using unix shell
e.g.:
'!echo ERROR ON FILE >&2'

I've just tried and it seems to work

bye bye

Subject: [gradsusr] error with fprintf command (dipak sahu)
Message-ID: <CAMUironTPfwN=9SeKSFADRR66rsBz6GLk0P+nKUbf+h2CO9+PQ@mail.gmail.com>

hi Dipak,
 I think with the fprintf function u will have to set y values also. From
the script u sent

> set x 1 54 (since the .dat file has 54 longitude and 36 latitude points)
> set t 25
> fprintf  t2-273.15   T2-24hr.csv  %g, 54
u are varying x dimension at some constant time, what about y?? But then
also your output file should contain only one row of 54 values since by
default grads must have set latitude to the first value in the domain. Try
by giving some value to y dimension.

Bye
Roopa

Hi Dipak,

*
Look at the foll two lines
ga->* set x 1 72
*ga->* fprintf ts ts.csv %g, 72 0

I think you should give

set x 1 54
> set t 25
> fprintf  t2-273.15   T2-24hr.csv  %g, 54 0
try it and let me know or else if poss send me the data i will check.

Bye
Roopa

This is a bug that has been fixed for the next release. The problem  
was that the subroutime gxqdrgb() needed to be moved from gxhpng.c to  
gxX.c. It will compile as is if you enable the printim command, which  
needs zlib, libpng, libjpeg, and libgd. Also, you need to add -lrt to  
the list of libraries to link with, that will fix the undefined  
reference to clock_gettime. Please have a look at http://iges.org/grads/gadoc/supplibs.html

You did not include the ncdump output that shows the metadata for the  
coordinate axis "lev" -- it may have been insufficient. If that is the  
case, then GrADS won't recognize variables that use that coordinate  
axis. Furthermore, you need to include the version of GrADS you are  
using, since the sdfopen interface has changed over time and this  
information may be quite relevant. After you have sdfopen'ed your  
file, try a 'q file' and see if it has found a z-axis with levels that  
match the ncdump output. If not, then you will need to write a  
descriptor file, either a short version for the xdfopen command, or a  
complete one for the open command. The documentation is at http://iges.org/grads/gadoc/SDFdescriptorfile.html

Subject: [gradsusr] LFC calculation
Message-ID: <4E301AEA.7030108@meridian-enviro.com>

Meredith,

I ran into a similar problem while attempting to compute condensation 
pressure deficit (CPD). My solution was to derive an equation for my 
value of interest and then implement it in GrADS. Deriving the equation 
was the most difficult portion of this task. Once I had that in hand, I 
used several steps to bootstrap the solution in GrADS. For example, my 
CPD equation requires virtual temperature and the change in height by 
way of the hypsometric equation. For one step, I calculate the virtual 
temperature grid. In the next step I use the calculated virtual 
temperature grid in the hypsometric equation to find the change in 
height. For my way of thinking, a step-wise process, taking each piece 
in a small chunk, is easiest to comprehend during the testing phase. 
After you verify your solution works, you can refine the method to 
improve your processing efficiency.

In my experience, you can "define [var]=[eqn]" to create the appropriate 
gridded variable. If you have x and y varying (for a single time), 
you'll calculate the variable for each gridpoint in your domain or vary 
x, y, and t for multiple time steps in your domain.

Hope this helps.

+++Begin copied text+++

Hi Everyone,

I'm looking to plot a contour plot of LFC height, similar to the graphic
on the SPC Mesoscale Analysis page, my control file does not output LFC
directly,  is there anyway I can calculate this in grads?

Thanks for your help.

You may just need to set your time interval to something different. Try

set t 1 50
in grads command line

to see the temperature in kelvin for the first 50 timesteps. You should see
contour plots pop up really quickly, starting from the first timestep and
stop at the 50th timestep for your domain. I hope that works.

Estefan?a:

Another thing to check is your file names.  In the ctl file you specify:
*Eta_exp110km1960010100+%y4%m2%d2%h2.bin
*which means when/if you "set t 1", it will look for a file called:
*Eta_exp110km1960010100+1960010100.bin

*If you do not have such a file, you'll get all undefined values.  I suspect
that the first part of the file probably changes as well?  Or maybe you
have the data files in a subdirectory?

Turns out the subsetting *is* the culprit... changed it from the CONUS to
US/Canada/Alaska and it actually downloads (insignificantly) faster... I'll
try testing raw data downloads sometime too (especially since I can use
parallel connections without bogging down the NOMADS server). Oh, and I
implemented the staggered downloads and now have a lag of about 2-4 seconds
for the first map and 12-20 seconds for the last map (GrADS is really fast
at generating maps... at least when the right settings are used on printim).

Thanks,
Joey

Hi all,

I finally solved my problem by converting the time axis from absolute to 
relative with "cdo -r copy inputfile outputfile".

HB,

Here's an example of plotting vertically averaged wind streamlines for a
single timestep from a forecast model:

'set time 00z30jul2011'
'define u=ave(ugrdprs,lev=1000,lev=300)'
'define v=ave(vgrdprs,lev=1000,lev=300)'
'set gxout stream'
'd u;v'

I have downloaded teh file orog.spec.nc but I cannot think of how to use it.

Many thanks.

Subject: [gradsusr] how to display collected data when T varies
Message-ID: <BLU136-W297E5BB07055DAA09F82C1EA370@phx.gbl>


Hi All,
Have a set of WRF output data, post processed into GRADS data (de.ctl and de.dat). The data is for couple of days with time increment 3hrs. 
Want to plot out the average OLR along a slant line (cross section, say from 40E 10N to 70E 25N) with 10 degrees in latitude. We can do this easily if the averaging is along a straight line (e.g. ave(olr,lat=5,lat=15) for lon 40 70). 
Tried "collect" and "gr2stn". "collect" works for data varying in Z or T; I can collect the averaged values of OLR with varying T. However, "gr2stn" works only for varying Z, not T. 
Question: How do I display the collected data with varying T? It seems that I can't use "gr2stn". 
Thanks. 
Liping

Hi Eduardo.
You can download the topo data from this link:
http://users.ictp.it/~pubregcm/RegCM3/globedat.htm#part5
for display Topography in contour or shaded format just type these command
in GrADS terminal:
set lat x1 x2
set lon y1 y2
set gxout contour(or shaded)
d EXPR

Subject: [gradsusr] define a simple scalar
Message-ID: <4E3454C8.8000003@ucsd.edu>

Hello,

I'm having a problem with what I'm sure is a simple task.  I want to 
define a scalar to convert a slope (i.e. units/year) into a trend line 
over several years.  I'm using this to detrend a time series.   
Basically I just need to construct a simple scalar (i.e. variable = 1 2 
3 4 5...) or a variable that equals the year of each entry of my dataset 
(i.e. variable = 1991 1992 1993 1994 1995...) that I can multiply by my 
slope values.  I can use tloop to create the right dimensions (variable 
= 1 1 1 1 1...) but I can't seem to get the values to increase for each 
time step.

Imagine I could either create a datafile manually and read it in or 
somehow extract the year information from the existing dataset into a 
user defined variable.

Is there an equivalent of 'define variable(t=2) = 2'?  I know this 
syntax is wrong.

Any advice would be appreciated.

Lisa

set t 1
variable1 = const(kanto, 1, -a)
set t 2
variable2 = const(kanto, 2, -a)

where "kanto" is any variable in the file.

AFAIK there is no way to define different timesteps of the same variable in
different ways. A for loop can take care of the trouble involved with using
multiple variables.

Helloo,
          Which data you want to plot using stationgrads.  I know how to
plot rainfall data using station grads. If you want rainfall data to plot
then probably I can help. What you need is to have an ascii file of data.
Let me know your specific requirement.

Kindly send me one sample of your ascii file including latitude, longitude,
station name year, date , rainfall etc. Let me try and after that I will
send you the programs and required gs files and the procedures needed to
plot the file in grads. Best of luck.

Hi All,

I would to use NCEP/NCAR Wind Speed Data which is available at 2.5 x
2.5 degree for Trend analysis & correction factor. Initially, I would
be interested in undergoing ?two tasks :

1. would like to interpolate the WS data from 2.5x 2.5 degree to 1 x 1
degree using GrADS. I understand GrADS is the best tool for displaying
and interpolating the same. Can anybody help me how to do this, please
send me codes & conceptual help as well.

2. Secondly, ?I am using Window as Operating system and I need to
install the same in my System. I have tried quite often but was
unsuccessful.While installing, it always ask for cywgin ?platform it,
and error message is popped up showing .dll is missing. Please help my
in this regards and send a complete packet of setup files and
installation guide describing the various steps to be followed in
sequential manner.

Regards,

Zia

Try running GrADS in verbose mode to see what exactly is wrong.
