Stephen,

  Here's a simple write to text code I use for a readme file it also
has a loop that goes through group of cells.  It's something you could
modify.

///Start Code///
'Write the Initials to a Text file for the QA monitors to use
        Const DELIMITER As String = "" 'Normally none
        Const PAD As String = " "   'or other character
        Dim vFieldArray As Variant
        Dim myRecord As Range
        Dim nFileNum As Long
        Dim i As Long
        Dim sOut As String

        'vFieldArray contains field lengths, in characters, from field 1 to N
        vFieldArray = Array(20, 10)
        nFileNum = FreeFile
        Open qaLocation & "Initials_Key_Readme.txt" For Output As #nFileNum
        Print #nFileNum, "**********************************"
        Print #nFileNum, "* The Initials Key for the QA     *"
        Print #nFileNum, "**********************************"
        Print #nFileNum, ""
        Print #nFileNum, "Name                Initals"
        Print #nFileNum, ""
        For Each myRecord In Workbooks(1).Worksheets("Master").Range("D7:D25")
            With myRecord
                For i = 0 To UBound(vFieldArray)
                    sOut = sOut & DELIMITER & Left(.Offset(0, i).Text & _
                            String(vFieldArray(i), PAD), vFieldArray(i))
                Next i
                Print #nFileNum, Mid(sOut, Len(DELIMITER) + 1)
                sOut = Empty
            End With
        Next myRecord
        Print #nFileNum, ""
        Print #nFileNum, "* If your initials aren't what you normally use"
        Print #nFileNum, "then you need to have the POC for your QA program"
        Print #nFileNum, "change them in the master. Changes will not
take effect"
        Print #nFileNum, "until the next month!"
        Print #nFileNum, ""
        Print #nFileNum, "This initials file is vaild for the " &
qaDate & " Excel file"
        Close #nFileNum

///End Code///

Might not be the most professional of codes.  Hope this helps get you started.

Shawn,
Thanks for sending the "simple" sample code for writing to a text file.
However, I was looking for sample code for creating the type of station data
file (binary) specifically suited for GrADS use.  I was actually looking for
an Excel VBA translation of the sample Fortran or C codes shown in the GrADS
Users Guide.  Sorry if my query wasn't clear enough.

I do appreciate your response, and it should be a useful answer for related
questions.

Please see http://iges.org/grads/gadoc/supplibs.html for the list of  
supplemental libraries you need to build in order to enable printim  
and the xdfopen command. To enable printim, you need zlib, libpng,  
libjpeg, and libgd. For xdfopen you need netcdf and udunits.

Hi users,
 
New to grads (using for 3 months now).
 
I was wondering what the best way to extract a time series of values at a point on a grid.
I'd like the values to be output to a text file. 
The grid is of netcdf format.
 
So far I constrain the grid to one point and use set gxout value to give me a plot on the grads display. How can I get this into a text file?
 
regards,

Mr. Seemanth M. generously contributed his script "Text output of data from
a non-uniform latitude interval grid" to get the text output of binary data
for a region for different time step. Here longitude has uniform interval
and latitude is varying with irregular interval.

Mr.Prejesh A.G. generously contributed his script for "Matrix text output of
data" to get a gridded ASCII output of 6 hourly U component wind of one
month data from ecmwf. Jan 28, 2010 12:53 PM

see
http://sites.google.com/site/modellingearth/chapters/software-tools-list/sample-codes/grads-code

But in your case, you need only the output for single point and it would be
much easier if you refer to the scripts mentioned above.

Mogesh,
Try the following:

'set gxout fwrite'
'set fwrite?[INSERT YOUR FILE PATH AND FILE NAME HERE]'?? (example: 'set fwrite c:\mogesh\variable.txt')
'd VARIABLE'??
'disable fwrite'


?(VARIABLE is whatever you are writing out.....) Also, all of your calculations and geographic settings should be done prior to the 'set gxout fwrite' line. 


This should write out your variable to a .txt file in the path name that was supplied. 
good luck,
teddy

Hai Mogesh,

See the attached sample program. In that the output will be written to a
file called sample.txt

Teddy,
'set gxout fwrite' gives you a flat binary data file.
why would Mogesh want to write it to a file called variable.txt?
it won't be text output but binary.

This topic about writing text comes up a lot!

Anywhoo .. short form is to 

- set gxout print 
- d <whatever>	- which will write something but also send it to the grads pre-defined "result"
- write "result" to file

Here is a script I use to write out some results to a file. It has a bunch of hardcoded variable names and paths - but you can probably modify it to suit your needs.  There may be other, better ways to accomplish this task .. but this works for me.



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

* Script in testing to write data values at lat/lon (not using gr2stn - just
* nearest grid point) to a file.
*
*
* Set the list of Variables, and some name-mapping that I'll remember.
* Should be in a read-config file, but we shall throw it in here for now.

var.1.1 = 'TMPl11910000 - 273.16'
var.1.2 = 'Surface Temperature'

var.2.1 = 'TCDCsfc'
var.2.2 = 'Cloud Cover'

var.3.1 = 'TMPPRS(lev=850)'
var.3.2 = 'Temperature 850mb'

NumVars = 3

* For now - pretend the grib file is open
*

* Read in the list of stations and the lat/lon and put into a some
* global variables

site = 1
while (1)
  result = read("/home/ron/GEMLAM/Meteograms/stn.cfg")
  EOF = sublin(result,1)
  if (EOF = 2)
    break
  endif
  line2 = sublin(result,2)
  _name.site = subwrd(line2, 1)
  _lat.site = subwrd(line2,2) 
  _lon.site = subwrd(line2,3)
** say "name is " _name.site ' ' _lat.site ' ' _lon.site
   site = site + 1
   
endwhile

_NumSites = site - 1

* Set the time to 1 and do an inquiry on the
* time.  We can use this to get the date/time
* of our data. Will be used in the name of
* the output file

'set t 1'
MyDTStamp = DateTimeStamp()
say "Date Time Stamp is " MyDTStamp


* Now get the time range of our data, as
* we want to loop through all time periods
* For now, user will just have to know what
* the time increment is

'q file'
MyLine    = sublin(result, 5)
TimeSteps = subwrd(MyLine, 12)
'set t 1 ' TimeSteps


* Loop through the sites and print out some values to
* a file.  For now, just one big file but it could
* just as easily be a seperate file for each station.
*
* For now, just hardcode the name of the variable that is
* desired.  I might make some more obvious names later as
* I'll want to use them in the GribViewer program

MyFile = MyDTStamp".txt"
rc = write (MyFile, 'Model Run ' MyDTStamp )

'set gxout print'
'set prnopts %6.1f 17'

MySite = 1
while (MySite <= _NumSites)
  say 'working on  '_name.MySite
  'set lat ' _lat.MySite
  'set lon ' _lon.MySite 
  rc = write(MyFile,'')
  rc = write (MyFile, 'Station '_name.MySite' ' _lat.MySite ' ' _lon.MySite)
  MyVar = 1
  while (MyVar <= NumVars)
    'd ' var.MyVar.1 
    rc = write(MyFile, var.MyVar.2) 
    MyResult = sublin(result, 3)
    
    say MyResult
    
    rc = write (MyFile, MyResult)
    MyVar = MyVar + 1
  endwhile
  MySite = MySite + 1
endwhile







*-------------------------------------------------------------- 

function DateTimeStamp()

month.JAN = "01"
month.FEB = "02"
month.MAR = "03"
month.APR = "04"
month.MAY = "05"
month.JUN = "06"
month.JUL = "07"
month.AUG = "08"
month.SEP = "09"
month.OCT = "10"
month.NOV = "11"
month.DEC = "12"

  
'q dim'
rec = sublin(result,5)
time = subwrd(rec,6)

MyHour     = substr(time,1,2)
MyDay      = substr(time,4,2)

Subject: [gradsusr] Meridional gradient?
Message-ID: <1272918043.2537.11.camel@dogen.unm.edu>

Hello list,

I need to calculate the meridional temperature gradient across 20 degree
latitude belt using global gridded data. Below is what I did:

'open ta.ctl'
'set t 1'
'set lev 1000'
'set lon 0 360'
'set lat -80 80'
'define Tgrad=ta(lat+10)-ta(lat-10)'

However, Grads complained "Cannot use an offset value with a varying
dimension". If I set 'lat' at a fixed value, such as 'set lat 40', the
above script did work, but the downside is that this only gives
temperature meridional gradient at the specified latitude instead of
over the entire latitude range. Any inputs would be highly appreciated!

Best,

Li

Li,
If you want to find a temperature gradient, why not just use cdiff?  Just
realize that you'll have to use the following expression for dy (the
incremental change in meridional distance between grid points, in meters):

dy = Re*cdiff(lat,y)*(3.14159/180)

where Re is the radius of the Earth (about 6.371e6 meters, I believe).
This is to account for the projection Grads uses to display your data.  Hope
this helps.

Dear Users,
Can anybody suggest how to plot a global data in spherical map projection in grads
I attached a example plot ( made in ferret),
Same kind of figure can be plotted in grads?

I found these options, but I did not find a right option for my requirement ( figure attached)
set mproj proj
Sets current map projection. Options for proj are:

latlon Lat/lon projection with aspect ratio maintained (default) 
scaled Lat/lon aspect ratio is not maintained; plot fills entire plotting area
nps North polar stereographic 
sps South polar stereographic 
lambert Lambert conformal conic projection
mollweide Mollweide projection
orthogr Orthographic projection
robinson Robinson projection, requires set lon -180 180, set lat -90 90
off No map is drawn; axis labels are not interpreted as lat/lon 


Kindly Suggest.........
Thanks in Advance
Anuradha

Hai Anuradha,

I dont know whether spherical map projection is available but you can use
Robinson projection which is similar for this purpose. The easy method is to
use map.gs form grads script library

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

copy it to grads library or you data folder. then type "map". There you have
several options in which you select "robinson". Then plot the varible. It
will be like the attached figure. Also i am attaching a copy of the map.gsfile

Krish,

When we are focusing on Pacific ocean, it is better to vary longitude from 0
to 360, so that we can get 180E at the central  portion of the plot. But, I
think, it is not supported by Robinson projection. I once tried the
following code

'open ../data/sst.ctl'
'set mproj robinson'
'set lat -90 90'
'set lon 0 360'
'set t 1'
'd sst'

For this I recived an error message as follows.

"Map Projection Error:  Invalid coords for Robinson
  Will use linear lat-lon projection"

I expect that this may be the problem facing by Anuradha.

Subject: [gradsusr] Calculate monthly totals for time series
Message-ID: <038600D27354214A8013AFE83F226593E4191912@MBX05.stf.nus.edu.sg>

Hi all,

I have a WRF output for 1 year with 1457 time steps ( 6 hourly rainfall)

Since this is accumulated, I usually do,

Var(t+1)-Var(t+0) to get the daily values.

Question:

Is there an easy way to calculate the monthly totals by subtracting by each months so that I can draw an annual  time series ..

How do I modify the script??

Many Thanks,

Sri

Dear GrADS Users,

I'm using this attached script to obtain a seasonal average (JJAS) of
Rainfall from APHRODITE high resolution daily rainfall gridded dataset.
It works with the older version (V1.8) but when i try it in Grads V2.0.a4 an
error occurred "segmentation fault". The advantage of using
the later version is, it was able to write an output to NetCDF format that's
why I tried to switch into this version. Is defining a lot of variables
its limitation?

Has anyone encountered similar problem? I need your help...

Thanks in advance!

Mar

Hai Gibies,

As the documentation says

"Robinson projection, requires set lon -180 180, set lat -90 90"

so it wont work for your program

Hello Mar,

The segmentation error is due to the overflow of allotted memory
Here you are using 30 variable p61, p62, ........p90 simultaniousely. You
can avoid the problem by using a loop

......
......
......
yyyy=1961
define sum_p = .....
while(yyyy<1990)
.....
.....
define p_n = ......
sum_p= sum_p + p_n
.....
.....
yyyy=yyyy+1
endwhile

define pave=sum_p/30

........

Hello Mar,

Don't forget to undefine the variables after its use.

Hi Gibies and Krish,
As gibies said, I got the same error when I used 
set mproj robinson

But, according to krish suggestion, I copied map.gs in grads/lib
Then done the following

'open model-temp.ctl'
'map'
'sh'
'd temp'

By running this script, it will prompt 
enter projection: robinson

Then I got my required plot 

Thank you Krish and Gibies

With Regards
Anuradha

??Arlindo,
??I'm also interested in the anwser to your problem. I have a similar one: I need to interpolate irregular station data to a regular grid of 8x8km, but I don't know how to properly import the station ASCII data into GrADS and perform a interpolation method (probably kriging?)...
??Please let me know if you find a solution...

Dear all,

I am trying to put monthly station data on 0.5?X0.5? grid. ?I can read the data using a FORTRAN code but I do not know how to transform these irregular data to a regular grid (0.5?X0.5?). 
?
?
Can anyone help me on that??

Hi users,
 
I am creating a line graph using my model output and on the x-axis
instead of having UTC I would like to have local time (ie EDT), can
anyone tell me if this is possible and how to do it?  
 
Thanks very much for your help.

Meredith,
Use the command "set xlabs (time 1) | (time 2) | ...".  Just make sure you
know what the actual axis label values correspond to in LT, because you have
to input all of the labels manually with that command.  Hope this helps.

the GRIB data for GrADS has even grids, so I am wondering whether it is

The GrADS Users Guide, in the "Creating a Station Data File" section, shows
a short sample dataset as follows:

1980     2     TTT    33.4  -82.5     45.5

I output the attached (test.sta.dat) binary file using an Excel VBA macro,
shown here:

Private Type stadathdr         'data type "station data header" (len=24)
    stid As String * 8      'station ID (e.g., "QQQ")   len=8

    For r = 1 To rnum     'loop through data rows, read in data
        yr = ActiveCell.Offset(r, 0)
        mo = ActiveCell.Offset(r, 1)
        hdr.stid = ActiveCell.Offset(r, 2)
        hdr.lat = ActiveCell.Offset(r, 3)
        hdr.lon = ActiveCell.Offset(r, 4)
        rf = ActiveCell.Offset(r, 5)
        If flg = 1 Then
            oldyr = yr: oldmo = mo: flg = 0
        End If
        If oldyr <> yr Or oldmo <> mo Then  'if new time group
            hdr.nlev = 0
            Put #1, , hdr     'write station header/time group terminator

            'rec = rec + 1
        End If
        oldyr = yr: oldmo = mo
        hdr.tim = 0#: hdr.nlev = 1: hdr.nflg = 1
        Put #1, , hdr    'write station header

    Next r
    hdr.nlev = 0
    Put #1, , hdr     'write last time group terminator
    Close #1
End Sub

When I ran the stnmap utility, here were my results:
>stnmap -i c:/projectmgr/stationdata/out/test.sta.ctl
  Name of binary data set: c:\projectmgr\stationdata\out\test.sta.dat
  Number of times in the data set: 2

Starting scan of station data binary file.
Binary data file open: c:\projectmgr\stationdata\out\test.sta.dat

Processing time step 1
  Invalid station hdr found in station binary file
  Possible causes:  Invalid level count in hdr
                    Descriptor file mismatch
                    File not station data
                    Invalid relative time
                    Invalid sequential format
    levs = 1123457434  flag = 542265938  time = 9.18369e-41

It appears the station data file was not properly formatted.  Perhaps
someone can understand why I'm getting this result, and how to resolve.

Thiago,

there are two grads function to interpolate or 'analyze' station data to
a grid:

1) oacres  -- Cressman successive scan analysis; and one i wrote:
2) oabin  -- 'bin' the obs in a grid box(is the ob inside the box?  if
so accumulate and the set the grid point value to the mean)
 
see the grads doc:
http://grads.iges.org/grads/gadoc/gadocindex.html

ciao ciao,  mike

Hello All,
I'm doing snow Research and looking for a program to covert the climate
prediction center (CPC) Northern Hemosphere raw weekly snow data (in 1's and
0's) into a useable number. I don't have much coding experience or computer
science background, so i'm not sure how to covert the data myself, or what
program to use. Also I don't have any fortran compiler. The CPC does covert
the data into a nice table format, but they don't keep it up todate. Their
website is http://www.cpc.ncep.noaa.gov/data/snow/. On their website they
have a link to grads.

The program they give for reading weekly 89*89 snow data is

I'm using windows 7 64bit operating system. My question is how do i use
grads to view the snow data or is there a fortran compiler the above program
will work on that i should use instead?
Thanks,

Hello everybody

I am using "cdiff" function along z-dimension to fine dvar/dz e.g

-> 'set z 1 17'
-> 'define dvar = cdiff(var,z)

but I have following error

Error from CDIFF:  Specified dimension non varying

Muhammad,
Unfortunately, you simply can't define a variable using cdiff in the
z-direction in Grads.  You can display a variable, but you'd have to write
out the entire formula for that variable in the display command.

Message-ID: <u2s5825ce3f1005050838t934a899cka4f8112fb1ab4c3a@mail.gmail.com>

Dear Grads users,

I'm using 144 netcdf files from TRMM dataset. I'm trying to write a ctl file
but I'm not succeding, my ctl looks like this

DSET ^3B43.%y2%m201.6.nc
UNDEF 9999.9
OPTIONS template
DTYPE netcdf
XDEF 1440 linear -179.875000 0.250000
YDEF 400 linear -49.875000 0.250000
TDEF 144 linear jan1998 1mo
ZDEF 1 linear 1 1
vars 1
pcp 0 99 Precipitation
endvars


The name's files are

3B43.980101.6.nc
3B43.980201.6.nc
....
3B43.990101.6.nc
3B43.990201.6.nc
...
3B43.000101.6.nc

and so on

the ncdump for  is,

netcdf 3B43.090401.6A {
dimensions:
        time = UNLIMITED ; // (1 currently)
        longitude = 1440 ;
        latitude = 400 ;
variables:
        double time(time) ;
                time:units = "hours since 2009-4-1 0" ;
        double longitude(longitude) ;
                longitude:units = "degrees_east" ;
                longitude:long_name = "Longitude" ;
        double latitude(latitude) ;
                latitude:units = "degrees_north" ;
                latitude:long_name = "Latitude" ;
        float pcp(time, latitude, longitude) ;
                pcp:comments = "Unknown1 variable comment" ;
                pcp:long_name = "precipitation:Precipitation" ;
                pcp:units = "" ;
                pcp:grid_name = "grid-1" ;
                pcp:grid_type = "linear" ;
                pcp:level_description = "Earth surface" ;
                pcp:time_statistic = "instantaneous" ;
                pcp:missing_value = -9999.9f ;
}

Whenever I try to display the variable I get:

Cannot contour grid - all undefined values

Any help will be greatly appreciated

Luis,

Try these two changes to your ctl file: 1) change UNDEF to -9999.9 (if 
it is 9999.9) and 2) change TDEF's jan1998 to apr2004
If that doesn't work, here's a couple more ideas: 1) remove the "ZDEF" 
record in your ctl file (GrADS may not allow this, not sure) or 2) if 
you are using GrADS v2, you may be able to add a z-dimension to each 
netCDF file by reading in each netCDF using a GrADS ctl file and then 
write out the data using sdfwrite;  please find attached a GrADS script 
TRMM_3B42.gs in which a downloaded NASA TRMM 3B42 netCDF file is read in 
using a locally-constructed "xdfopen_ddf" (which defines z- and 
t-dimensions; technique courtesy of Jennifer Adams at COLA), regrids the 
precipitation to a user-defined grid (you can remove this) and then uses 
"sdfwrite" to write out a 4d netCDF file; please let me know if you have 
any questions about the script -- note for your case you already have a 
t-dimension so you can try removing the "TDEF" record in the 
"xdfopen_ddf" file).

Hope this helps,
Chuck

Bob,

Use a ftp client and go to ftp.cpc.ncep.noaa.gov<ftp://ftp.cpc.ncep.noaa.gov/> and then into the wd52dg/snow directory.

There is a wkly_89x89 directory. Download wk2010.

There is a progs directory and the readsnow.f file. Download readsnow.f file. Uncomment the open(unit=93 line and edit it to read the file wk2010 in your local path. Edit the open(unit=95 line to save the output file of a name of your choosing. Compile the application using 'gfortran -o readsnow readsnow.f'. Run it './readsnow'

There is a grads_snw directory and a control file. Download plt_snw.ctl and edit the top line to be the same name as your output file from unit-95 above.

grads -l
open plt_snw.ctl
d snow

If any of this makes no sense you need to take some basic IT and programming courses.

I'm using windows 7 64bit operating system. My question is how do i use grads to view the snow data or is there a fortran compiler the above program will work on that i should use instead?
Thanks,

If it is 36 kilometer CMAQ netCDF you can probably start with this grid control definition.

Hi,
   I have a 2D data set with uneven Lon and Lat distribution. I notice that the GRIB data for GrADS has even grids, so I am wondering whether it is possible to display this data set on GrADS? Thanks for help!

That is great! My grid size is 30 km instead of 36 km, and I think the
difference is trivial. I will read the format and modified it to my own
grid.
Thanks a lot!

Zablone,
I usually use a C program, taken from the format provided in the GrADS  
user pages. I tried it with your text data file and it worked (output  
rain3.dat).   Remember to first type stnmap -i stid.ctl.

The C program is attached.

good luck,
Lee

Thanks for your response Dr. Huddleston,
I just downloaded opengrads2.0.  I have found all the files you mention, but
i have trouble following the rest. I'm new to grads and computer
programming. It would help me out a lot to learn some of the basics of using
grads. For example,

'gfortran -o readsnow readsnow.f'
does grads have a compiler in it or is this something i need to download
seperately? Is there a tutorial for grads basic functions that could help me
learn more.

Also I'm not sure what "Uncomment the open(unit=93 line and edit it to read
the file wk2010 in your local path" means.

I know that most grads users have far better understanding of this kind of
stuff then me, but the grads webpage says
"Users at all levels are encouraged to post questions and answers on the
basics of getting started".

Thanks,
Bob

Subject: [gradsusr] getting x/y positions of contours
Message-ID: <4BE27494.2010605@hawaii.edu>


I was wondering if it was possible to get (x,y) or (lon,lat) positions 
of contour lines instead of, or in addition to, the lines being drawn on 
the page?  I'm trying to use GrADS to generate a contour plot, then 
display contours as lines on googlemap page.  I can do it as a raster 
over-lay, but the resolution is less than optimal, particularly when 
zooming.  Thanks in advance,

Jim

Subject: [gradsusr] Entire grid undefined
Message-ID: <i2lcf67f2c81005060620gff3cf74bvee0dd9c23b7b7913@mail.gmail.com>

Hello Grads users,
I'm having a problem with the post-processing of my wave model (WAM).
I run the model for distinct areas, using GrAds to display the results.
The .gs script that I use for all of the areas are the same model, changing
only the paths and names.
For one specific area (antartica), it's happening this:
The prognostics for some times (ex. 00, 06, 12) are working properly,
generating the figures, and then in the next time (ex. 18, 24, ..., 72) it's
coming out "ENTIRE GRID UNDEFINED", and the time that it begins to happen is
varying.
I dont know if it's a Grads problem or a problem inside the wave model...

Does someone have a guess?
Thanks,
Gabriel

Hello,
Can Grads read an ascii file .dat?
I supose I have to transform it to a GRIB file and then create a CTL for it,

how can I do this?
the file in question is attached, it's from the wave model SWAM.
Thanks a lot,

That's because GrADS constructs the defined object by looping over Z  
(and T and E if they are varying dims too). It's almost like a built- 
in zloop function -- you end up with a result that varies in Z, but  
the expression is evaluated at a fixed Z as it loops over all the  
specified Z levels.

That's correct. You can also write it out to a file, using gxout fwrite.

James,

If you save the image as a PNG or GIF, you can reference it using KML. Here is a hypothetical example.

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2">
 <GroundOverlay>
  <name>YourNameForTheImage</name>
  <Icon>
    <href>http://www.hawaii.edu/GeMaps/YourImage.png</href>
  </Icon>
  <LatLonBox>
   <west>        -130.25</west>
   <east>         -59.75</east>
   <south>          19.75</south>
   <north>          50.25</north>
   <rotation>0.0</rotation>
  </LatLonBox>
 </GroundOverlay>
</kml>

If you are using Google V.2 then it is straightforward.  If you are using V.3 then you may want to use GEOXML3. http://code.google.com/p/geoxml3/ 

Either way, rendering of GrADS images using KML is fast and efficient.

I was wondering if it was possible to get (x,y) or (lon,lat) positions 
of contour lines instead of, or in addition to, the lines being drawn on 
the page?  I'm trying to use GrADS to generate a contour plot, then 
display contours as lines on googlemap page.  I can do it as a raster 
over-lay, but the resolution is less than optimal, particularly when 
zooming.  Thanks in advance,

Do you have an example of a KML file (not created with GrADS) that has  
contours that can be displayed in Google Earth?

Luis,

Please find attached an email from Guilherme Martins illustrating how to 
use "sdfopen" itself to do the templating (if you can, I would try the 
"sdfopen" templating first without trying to add a z-dimension)... 
Thanks Guilherme!

Hope this helps,

My question relates to the use and templating of netcdf daily TRMM precipitation data (3B42), with opengrads 2.0.a7.oga.3. I've noticed a few threads on this subject but haven't been able to locate anything that helps me.

I can successfully open individual files. For example:
ga-> sdfopen 3B42_daily.2005.07.01.6.nc 
Scanning self-describing file:  3B42_daily.2005.07.01.6.nc
SDF file 3B42_daily.2005.07.01.6.nc is open as file 1
LON set to 0 360 
LAT set to -49.875 49.875 
LEV set to 0 0 
Time values set: 2005:7:1:0 2005:7:1:0 
E set to 1 1 
ga-> d hrf
Contouring: 0 to 330 interval 30 

Everything has the proper appearance.

I can do this for several files ... but I need to open tens of files at once, and need to template.

I created the following control file (control.ctl) based on users' suggestions, to template all my netcdf files (to start, for just 1 month):

DSET ^3B42_daily.2005.07.%d2.6.nc
DTYPE netcdf
OPTIONS template
UNDEF -9999.0
xdef 1440 linear -179.875 0.25
ydef 400  linear -49.875 0.25
ZDEF 1 linear 1 1
TDEF 31 linear 00Z1JUL2005 1dy
VARS 1
hrf  1 z,x,y daily precipitation [mm]
ENDVARS

Upon opening:
ga-> sdfopen control.ctl 
Scanning self-describing file:  control.ctl
gaopnc error: nc_open failed to open file control.ctl
read_metadata: gaopnc failed 
gadsdf: Couldn't ingest SDF metadata.

Or else:
ga-> open control.ctl    
Scanning description file:  control.ctl
Data file 3B42_daily.2005.07.%d2.6.nc is open as file 1
LON set to 0 360 
LAT set to -50 49.75 
LEV set to 1 1 
Time values set: 2005:7:1:0 2005:7:1:0 
E set to 1 1 
ga-> d hrf
NetCDF Error (gancrow, nc_get_vara_double): NetCDF: Start+count exceeds dimension bound
Data Request Error:  Error for variable 'hrf'
  Error ocurred at column 1
DISPLAY error:  Invalid expression 
  Expression = hrf

No doubt I'm doing something silly ... I would appreciate any suggestions.

thank you,

Matt,

See http://grads.iges.org/grads/gadoc/templates.html

Your TDEF number looks to be too small.

How many total days are in all the files in your template? Change 31 to that number.

Thanks for your reply John.

The tdef number is appropriate for 31 days (number of days for the month), but i could not even plot anything for t = 1, so that wasn't the main problem.

It was indeed the control file. I've modified it to:
DSET ^3B42_daily.2005.07.%d2.6.nc
DTYPE netcdf
OPTIONS template
UNDEF -9999.9
xdef 1440 linear -179.875 0.25
ydef 400  linear -49.875 0.25
ZDEF 1 linear 1 1
TDEF 31 linear 00Z1JUL2005 1dy
VARS 1
hrf=>prate 1 t,y,x daily precipitation [mm]
ENDVARS

and it works fine now. Primary parameter that I changed was the variable name definition and ordering of dimensions.

thank you,
matt

John,
   I start to work on the .ctl file, and I have a question about the xdef
and ydef. As you plotted, the left corner is not the minimal longitude and
latitude of the domain. Which value should I use?

Best

Hao

Matei,

One possibility is in your VARS "hrf" definition: try "t,z,y,x"... or 
better yet, have you tried the "sdfopen" templating method?  Please see 
a recent post I sent containing an email attachment with an email 
Guilherme Martins sent me for an example of how to do this... For more 
info on sdfopen templating: 
http://grads.iges.org/grads/gadoc/gradcomdsdfopen.html  If neither of 
these work, a "chsub" templating method worked for our TRMM 3B42 
3-hourly regridded precipitation datasets 
(http://grads.iges.org/grads/gadoc/templates.html, GrADS template ctl 
file attached).

Hope this helps,
Chuck

CMAQ files usually are ioapi or WRF compliant. If they are ioapi, run the 'ncdump -h file.ncf > h' and look at the global characteristics.  It will have everything you need to compose the control file.

If they are WRF compliant, you will have to go back to the modeler who created them.

Please see http://www.nco.ncep.noaa.gov/pmb/docs/on388/tableb.html#GRID138 as an example of the information you need.

John,
   I start to work on the .ctl file, and I have a question about the xdef and ydef. As you plotted, the left corner is not the minimal longitude and latitude of the domain. Which value should I use?

That is great! My grid size is 30 km instead of 36 km, and I think the difference is trivial. I will read the format and modified it to my own grid.

If it is 36 kilometer CMAQ netCDF you can probably start with this grid control definition.

Hi,
   I have a 2D data set with uneven Lon and Lat distribution. I notice that the GRIB data for GrADS has even grids, so I am wondering whether it is possible to display this data set on GrADS? Thanks for help!

Hello all,

I have a plt_snw.clt file and a snow2010.gdf file on my desktop, But when I
open grades, tell it landscape, and type
open plt_snw.clt
It says
Scanning Description file: plt_snw.clt
OPEN ERROR: can't open description file

I just downloaded grades 2.0.a7.oga.3 self extracting widows version  last
night and haven't done anything to it yet. I'm using windows 7 64 bit.
Is there something I'm missing?
Thanks,
Bob

Hai,
 i want to plot precipitaion anomoly.i hv cmap data precip.mon.mean.nc.t
the gs file i used for this is.

the problem is that in the saved plot didplay did not came........please
help me

'set grads off'
'set t 1 12'
'set gxout shaded'
*'set gxout contour'

'define monavg=ave(precip,t+1,t+36,12)'
'modify monavg seasonal'
'set t 1 last'
'define anom = precip-monavg'
*'set t 1 36'

Anuradha,

    The plot which you have attached is using "Mollweide projection". It is
available in GrADS

Try this code
'open ../data/sst6098.ctl'
'set mproj mollweide'
'set lat -90 90'
'set lon 0 360'
'set t 1'
'd sst'
'set gxout shaded'
'd sst'

Message-ID: <k2g5ed20271005070441p5e7d3efiddec1e78e6813f9a@mail.gmail.com>

Hello Friends,

I am facing a problem while using xdfopen command in GrADS Version 1.8SL11

My data discripter file (dsptr./ctl) is as follows

DSET /gpfs2/home/kiran/freerun/t62/monthly/time_mean.%y4%m2.nc
  OPTIONS template
   DTYPE netcdf
   TDEF 1200 linear jan2000 1mo

Then I tried to open the data using xdfopen. This is the response from the
system.

Issue 'q config' command for more information.

Landscape mode? (no for portrait):

ga-> xdfopen dsptr.ctl
Scanning Descriptor File:  dsptr.ctl

udunits(3): Couldn't open units database "/usr/local/lib/grads/udunits.dat":

*UDUNITS package initialization failure*.

Can anybody tell what is this UDUNITS Package

Thanking you in advance

Hello Gabriel,

The message "ENTIRE GRID UNDEFINED" usually appear when GrADS could not open
the data variable which is given for display. I think there may be a problem
in the communication between your model and GrADS.

Jeevan,

The problem is with the time definision

There two way of defining time

set t 1

or

set time 01jan2010

Your variable mmm is now having integer value. You have to convert it into
three letter string. For that use the following code

n=m1
if(n=1)
 mmm='jan'
endif
if(n=2)
 mmm='feb'
endif
if(n=3)
 mmm='mar'
endif
if(n=4)
 mmm='apr'
endif
if(n=5)
 mmm='may'
endif
if(n=6)
 mmm='jun'
endif
if(n=7)
 mmm='jul'
endif
if(n=8)
 mmm='aug'
endif
if(n=9)
 mmm='sep'
endif
if(n=10)
 mmm='oct'
endif
if(n=11)
 mmm='nov'
endif
if(n=12)
 mmm='dec'
endif

then you can use format

'set time = 'dd''mmm''yyyy

Refine your code and try.

Regards

John,
   I get the WRF WPS projection information as following:

e_we              =  98, 118,
 e_sn              =  70,  103,
 geog_data_res     = '10m','2m',
 dx = 30000,
 dy = 30000,
 map_proj = 'lambert',
 ref_lat   =  34.8,
 ref_lon   = 113.7,
 truelat1  =  30.0,
 truelat2  =  60.0,
 stand_lon =  113.7,

My key point here is : CMAQ domain is a little bit smaller than WRF domain
because we eliminate the outside columns and rows to diminish lateral
effects. So my WRF domain has 98*70 grids while my CMAQ domain has 94*67
grids.

so the question is: how to set (isize, jsize) and (iref, jref) in pdef
variable? I am confused.

Best

Hao

Hao,

Based on the information you sent, here is a representative control file to plot your (COL,ROW)=(94,67) grid.

dset ^YourFile.ncf
dtype netcdf
title Vertically integrated atmos chem/aerosol vbles
pdef 94 67 lcc 24.828 100.01 1 1 30 60 113.7 30000 30000
undef -9999
xdef 94 linear  95.769    0.3659
ydef 67 linear  24.828    0.2644
...

John,
   I get the WRF WPS projection information as following:

e_we              =  98, 118,
 e_sn              =  70,  103,
 geog_data_res     = '10m','2m',
 dx = 30000,
 dy = 30000,
 map_proj = 'lambert',
 ref_lat   =  34.8,
 ref_lon   = 113.7,
 truelat1  =  30.0,
 truelat2  =  60.0,
 stand_lon =  113.7,

My key point here is : CMAQ domain is a little bit smaller than WRF domain because we eliminate the outside columns and rows to diminish lateral effects. So my WRF domain has 98*70 grids while my CMAQ domain has 94*67 grids.

so the question is: how to set (isize, jsize) and (iref, jref) in pdef variable? I am confused.

Best

Hao

This can be done more elegantly, as follows:

mons='jan feb mar apr may jun jul aug sep oct nov dec'
n=1
while (n<=12)
mmm=subwrd(mons,n)
...
...
n=n+1
endwhile

thus eliminating the need for 12 different 'if/endif' structures.

Jeevan,

The problem is with the time definision

There two way of defining time

set t 1

or

set time 01jan2010

Your variable mmm is now having integer value. You have to convert it
into three letter string. For that use the following code

n=m1
if(n=1) mmm='jan'
endif if(n=2)
mmm='feb' endif
if(n=3) mmm='mar'
endif if(n=4)
mmm='apr' endif
if(n=5) mmm='may'
endif if(n=6)
mmm='jun' endif
if(n=7) mmm='jul'
endif if(n=8)
mmm='aug' endif
if(n=9) mmm='sep'
endif if(n=10)
mmm='oct' endif
if(n=11) mmm='nov'
endif if(n=12)
mmm='dec' endif

then you can use format

'set time = 'dd''mmm''yyyy

Refine your code and try.

Regards

Hello ,

Since the files essential to grads operation are not in /usr/local/lib/grads, you must set the environment variable GADDIR:

setenv GADDIR /gpfs1/scientific_appln/grads-1.8sl11/data (if you use csh)

or

GADDIR=/gpfs1/scientific_appln/grads-1.8sl11/data
export GADDIR

(if you use sh/bash).

Yes it can, all you have to do is to properly define the ctl file
associated with your data. I attach an example for grads v2.0.a8

hope it works for you

Hao,

You are welcome. 

The (24.828,100.01) is the lower left corner of your CMAQ grid. I simply dumped the x,y data, sorted it, and found the point.

95.969 is the longitude of your upper left corner and 131.2617 is the longitude of your upper right corner. Take the difference and divide by 94 to get the x delta.

Similarly, take the difference between your lower and upper latitude and divide by 67 to get the y delta.

John,
?? Thanks a lot! It looks very nice. Can you tell me how to calculate the latref (24.828N), lonref(100.01), xdef and ydef? I have another nested domain, and I want to go through the process.

John,

?? I get the WRF WPS projection information as following:

e_we????????????? =? 98, 118,
?e_sn????????????? =? 70,? 103,
?geog_data_res???? = '10m','2m',??????????????? 
?dx = 30000,
?dy = 30000,
?map_proj = 'lambert',
?ref_lat?? =? 34.8,
?ref_lon?? = 113.7,
?truelat1? =? 30.0,
?truelat2? =? 60.0,
?stand_lon =? 113.7,

My key point here is : CMAQ domain is a little bit smaller than WRF domain because we eliminate the outside columns and rows to diminish lateral effects. So my WRF domain has 98*70 grids while my CMAQ domain has 94*67 grids.

so the question is: how to set (isize, jsize) and (iref, jref) in pdef variable? I am confused.

John,
   Thanks for your explanation! I will apply the similar method to my nested
domain and let you know the result next week.
Have a nice weekend!

Thank you Eric,

But I am using ksh

Which method should I follow in 'ksh'.

I have one more error as follows, probably from my descriptor file DSET tab.

/gpfs2/home/kiran/freerun/t62/monthly/time_mean.%y4%m2.nc does not exist or
is not a netCDF file.

Can you point out the problem?

I am trying to open the following files simultaneously.

/gpfs2/home/kiran/freerun/t62/monthly/time_mean.200001.nc
/gpfs2/home/kiran/freerun/t62/monthly/time_mean.200002.nc

........................
........................
.........................
/gpfs2/home/kiran/freerun/t62/monthly/time_mean.210012.nc

I have written xdf file as follows

DSET /gpfs2/home/kiran/freerun/t62/monthly/time_mean.%y4%m2.nc
OPTIONS template
DTYPE netcdf
TDEF 1200 linear jan2000 1mo

How can I modify it to avoid the error?

Thanking you in advance.

Subject: [gradsusr] how to set transparency with linefill ?
Message-ID: <AANLkTin-yCrrMgGZn4XRIBKC60WiSLz36ELoYn74cKBO@mail.gmail.com>

Dear All,

I can plot a line curve with shaded confidence intervals easily with grads.
For example, to draw the mean value of 'prec' in black over a color filled
area representing the +-1standard deviation around the mean I do:

'set lat 0'
'set lon 0 360'
'set gxout linefill'
'set lfcols 2 0'
'd prec+sd_prec ; prec-sd_prec'
'set gxout line'
'set ccolor 1'
'd prec'

My problem is: the color filled area resulting from a linefill is not
transparent!
Hence one can not see other curves below it.

Is there a way of setting the transparency of the shaded and/or filled
areas in Grads?

Maybe in PyGrads?

Hi,
I am testing the pygrads mainly for the eof capabilities.
I am using the pygrads-1.1.0.win32_superpack.exe, os winxp.
Assuming common install  (c:\python25) installation.
How would I tell it to open sst.mnmean.nc that's residing in d:\data?

I have tried different commands that usually works for grads, but no luck in pygrads.

Greetings fellow GrADS users,

I am using GrADS version 1.9b4 and/or the latest version of OpenGrADS.

My question is the following. Is it possible to change the x-axis scaling, and in particular, to have the x-axis in log scale, while retaining the y-axis as is (linear)?

thanks much,
matt

Hi Matt,

I rearranged my binary data such that the x-axis became the z-axis in grads,
which you can plot in log scale. I am not aware that you could do that with
the x-axis.

Heiner

Hello.

I have this file in the attachment.

 

It get 3 contains this parameters: ugrdprs, for levels 150/100, vgrdprs for
levels 850/150/100.

 

If I use this file in grads, it can display all the 3 levels for vgrdprs.

For ugrdprs the display command produces a correct map for level 150 and an
empty map for level 100 (Entire grid is undefined) and this message:

 



 

Why this behaviour? Can you say me what doesn't like to GrADS for ugrdprs on
level 100?

 

 

The products I'm using are:

grib2ctl v0.9.12.5p45

wgrib v1.8.0.12

GrADS Ver. 2.0.a7.1

 

The command I'm using before grads are:

perl grib2ctl.pl LFPW00190281.20090718151333_P4400PT7758_BPMG12.101562_1.b

If you look at your file with wgrib you will see that UGRD only has data at Z=150 and Z=100 whereas VGRD has data at all three levels 850,150, and 100.

The order of the ZDEF in the control file created by Wesley's grib2ctl.pl script is 850 150 100.

When you tried to display UGRD data it was using the 850 level.

Set your Z to 150 or 100 if you want to see UGRD data.

Oh, yes
surely I just setted the levels, with the ?set lev? command.

It doesn?t work for ugrd with the level 100 (with the level 150 there is no
problems).

 

Thank you,

Hello.

I don?t know if my question is clear, so let me repeat.

Using in GrADS the attached file, the ugrd can?t be displaied for the level
100.

Look at this pic in order to have clear the situation I have in GrADS

 



 

What is wrong in the attached file that prevent GrADS to display the data?

In the warning message I don?t see any abnormal situation: In my opinion,
the ?grid limits of request? appears correct in front of the ?grid limits of
file?, then what this message means?

Diego,
grib2ctl gives you a descriptor that looks like this (irrelevant stuff  
omitted):
zdef 3 levels 850 150 100
vars 2
UGRDprs 2 33,100,0 ** (profile) u wind [m/s]
VGRDprs 3 34,100,0 ** (profile) v wind [m/s]
ENDVARS

Because the number of levels in the UGRDprs variable declaration (2)  
is less than the number of levels in the ZDEF entry (3), GrADS assumes  
the only valid levels are the first two, and that is why it is giving  
you an error message when you try to retrieve data at Z=3. If you change
    UGRDprs 2 33,100,0 ** (profile) u wind [m/s]
to
    UGRDprs 3 33,100,0 ** (profile) u wind [m/s]
and rerun gribmap, using the -v option to make sure all the records in  
your file match, then everything will work the way you expect, and  
you'll have missing data for UGRDprs at 850 mb.

Dear list,

I need to calculate mass-weighted mean values of a variable, say air
temperature, from 1000 to 100 mb. The air temperature is at levels of
1000, 925, 800, 700, 600, 500, 400, 300, 200 and 100mb. I am thinking of
using function "vint" to perform this calculation. I'd appreciate if you
could verify if my script below is right.

'open ps.ctl'        (surface pressure control file, ps in millibar)
'open T.ctl'          (air temperature file)
'd vint(ps.1,T.2,150)/((ps.1-100)*(100/9.8))'

Note that the denominator is the scale factor (f/g) and the entire
column between surface level and top layer in millibar.

Thanks so much in advance!

Li

ok I just figured out that a simple . sdfopen d:\data\test.nc wil do...the dot was the problem...
maybe this will help others grads users using pygrads

  Hi,
  I am testing the pygrads mainly for the eof capabilities.
  I am using the pygrads-1.1.0.win32_superpack.exe, os winxp.
  Assuming common install  (c:\python25) installation.
  How would I tell it to open sst.mnmean.nc that's residing in d:\data?

  I have tried different commands that usually works for grads, but no luck in pygrads.

Diego,

grib2ctl.pl doesn't handle missing levels very well. grib2ctl found 3 
pressure levels as expected.

> * z has 3 levels, for prs
> zdef 3 levels
> 850 150 100
grib2ctl found UGRD on two levels and wrote the line
> UGRDprs 2 33,100,0 ** (profile) u wind [m/s]
With NCEP files, the missing levels occur at the smallest pressures, so 
"2" is ok. With
your file, the missing level was at 850, so you have to edit the ctl 
file and change the "2" into a "3".
> UGRDprs 3 33,100,0 ** (profile) u wind [m/s]
For what it is worth, a grib2 version of your data wouldn't have had a 
problem.

Great!!!!

Thank you Jennifer. I applied your suggest and it works fine.

 

Thank you so much again.

Diego, 

grib2ctl gives you a descriptor that looks like this (irrelevant stuff
omitted): 

zdef 3 levels 850 150 100

vars 2

UGRDprs 2 33,100,0 ** (profile) u wind [m/s]

VGRDprs 3 34,100,0 ** (profile) v wind [m/s]

ENDVARS

 

Because the number of levels in the UGRDprs variable declaration (2) is less
than the number of levels in the ZDEF entry (3), GrADS assumes the only
valid levels are the first two, and that is why it is giving you an error
message when you try to retrieve data at Z=3. If you change 

   UGRDprs 2 33,100,0 ** (profile) u wind [m/s]

to

   UGRDprs 3 33,100,0 ** (profile) u wind [m/s]

and rerun gribmap, using the -v option to make sure all the records in your
file match, then everything will work the way you expect, and you'll have
missing data for UGRDprs at 850 mb.

Using in GrADS the attached file, the ugrd can?t be displaied for the level
100.

Look at this pic in order to have clear the situation I have in GrADS

 

<image001.jpg>

 

What is wrong in the attached file that prevent GrADS to display the data?

In the warning message I don?t see any abnormal situation: In my opinion,
the ?grid limits of request? appears correct in front of the ?grid limits of

Oggetto: Why cannot contour grid for this file?

 

Hello.

I have this file in the attachment.

 

It get 3 contains this parameters: ugrdprs, for levels 150/100, vgrdprs for
levels 850/150/100.

 

If I use this file in grads, it can display all the 3 levels for vgrdprs.

For ugrdprs the display command produces a correct map for level 150 and an
empty map for level 100 (Entire grid is undefined) and this message:

 

<image002.jpg>

 

Why this behaviour? Can you say me what doesn?t like to GrADS for ugrdprs on
level 100?

 

 

The products I?m using are:

grib2ctl v0.9.12.5p45

wgrib v1.8.0.12

GrADS Ver. 2.0.a7.1

 

The command I?m using before grads are:

perl grib2ctl.pl LFPW00190281.20090718151333_P4400PT7758_BPMG12.101562_1.b

0.

 

 

Thank you in advance.

Subject: [gradsusr] plotting time in hovmoller pictures
Message-ID: <BLU136-W36D691CFBA180809722D1AEAFB0@phx.gbl>


Hi,   (I am a new user of GrADs)

I am trying to plot two hovmollers into one figure. The problem is the time. 
First I plot the hovmollers using data from file 1 for Aug10 to Aug15, with the following commands:

'set yflip on'
'set lev 1000'
'set tlsupp year'
'set t 2 48'
'set lat 15'
'set gxout shaded'
'set grads off'
'd ave(olr.1,lat=5,lat=25)'

So it gives me a figure for Aug10--Aug15. But, when I repeat the plotting for another period of time Aug15-Aug20:  

'set t 49 80'
'd ave(olr.2,lat=5,lat=25)' 

It will simply overlap the whole figure, the time is not sequenced. 

Question: what do I do to get the pictures of Aug10-15 and Aug15-20 laid out vertically (not overlapping each other)? 

An alternative way is to write the two sets of data into one data file. But I don't know how to do that either. 

Thanks for your help. Suggestions to either of the approaches are greatly appreciated!

Liping

Use 'set parea' to make it a multi panel plot and put the two plot areas
back-to-back.

Liping,
If you go to this web page:
http://grads.iges.org/grads/gadoc/gadocindex.html
and then read about vpage and/or parea you'll see what you
need to do to tell grads where to draw the plots.

Using vpage you can designate half the page for one plot,
then plot it, then use vpage to designate the other half of the
page for plotting the second plot.

If you want to connect the 2 plots, you may need to use
parea, but I believe vpage is the recommended way to
work with multiple plots on a single page.

Liping Liu,

You might also be able to use GrADS templates to "concatenate" the "olr" 
fields from file 1 and file 2 into a single time series within GrADS as 
follows:

'open olr_template.ctl'
'set yflip on'
'set lev 1000'
'set tlsupp year'
'set t 2 80'
'set lat 15'
'set gxout shaded'
'set grads off'
'd ave(olr,lat=5,lat=25)'

where "olr" is the name of the variable in the "vars" section of the 
GrADS template data descriptor file "olr_template.ctl" (please see the 
examples at http://grads.iges.org/grads/gadoc/templates.html which can 
give you some ideas for what your "olr_template.ctl" might need)... 
briefly, a template data descriptor file for  time differs from a single 
dataset data descriptor file in the "dset" record, a required "options 
template" record, and in the "tdef" record (in which the number of time 
levels in the template data descriptor file is the sum of the time 
levels for each of the component datasets).

I hope this helps,
Chuck

Message-ID: <2089ed6f$7aa2f554$5d6cc872$@com>

Dear Users,

I have installed Pygrads (in  Windows 7) for EOF analysis purpose. I am 
however unable to execute any commands like for Starting Pygrads provided 
in http://opengrads.org/wiki/index.php?title=PyGrADS_Interactive_Shell.

For example when I give the command : % pygrads -h  , I get the following 
error:

>>> % pygrads -h
Traceback (  File "<interactive input>", line 1
    % pygrads -h
    ^
SyntaxError: invalid syntax

It seems I am missing something. How should I go about it?

Thanks

Hello Wesley, how are you?.

Yes, yes, I understood. You and Jennifer have been very clear.

I just tried to edit the descriptor file ctl as you suggest, and it works
fine for level 100.

Ok, it means that, if necessary, I will split my file so that I will ensure
that there are only, in the produced files, parameters on the same list of
levels.

Thank you vey much to you all.

Diego

Diego,

grib2ctl.pl doesn't handle missing levels very well. grib2ctl found 3 
pressure levels as expected.

> * z has 3 levels, for prs
> zdef 3 levels
> 850 150 100
grib2ctl found UGRD on two levels and wrote the line
> UGRDprs 2 33,100,0 ** (profile) u wind [m/s]
With NCEP files, the missing levels occur at the smallest pressures, so 
"2" is ok. With
your file, the missing level was at 850, so you have to edit the ctl 
file and change the "2" into a "3".
> UGRDprs 3 33,100,0 ** (profile) u wind [m/s]
For what it is worth, a grib2 version of your data wouldn't have had a 
problem.

Hello,

does anybody have a fortran program which converts measured radar
reflectivity data to binary files read by grads?

Here is an example of my data files:

# Fields: z y x DBZ
# Units: km km km dBZ
1 -224.625 -224.625 35
1 -224.625 -223.875 28

1 -224.625 -222.375 20
1 -224.625 -221.625 18
......................

Thank you very much.

Diego,

When I have missing vertical levels, I use the grib2ctl/g2ctl option 
-no_profile. Then
each field will have it's own name such as HGT100mb. Another option 
besides editing
the files.

Oh Wesley,
you made me save a great job.

I tried to use the no_profile option and it works fine.

Thank you again,

Hi, 
Many thanks, especially to those who answered my previous question about plotting multi-figures into one page. 
Another question: I have my harddrive formatted in windows (ntsf), but now I want to download the files into my Linux laptop. 
Is there any way to convert the files into the format such that the Linux can read?

Go on to your windows box, create a user without admin, set an Id/Passwd for it, share the folder (yourShaeName) with your data, and set permissions to allow that new user to have read and write on it.

Go to your Linux box and install smbfs. Under Ubuntu it is 'sudo apt-get install smbfs'

Edit the /etc/fstab file on your Linux box and add a new line
//yourWindowsServerName/YourShareName  /mountDir  cifs   username=Id,password=passwd 0 0

Make the /mountDir directory

Mount /mountDir

Dear Marc, 
The Pygrads I had installed was pygrads-1.1.0.win32_superpack.exe   I hope 
you mean the same; and the version of Grads I am using is 
grads-2.0.a7.oga.3-win32_superpack.exe  . However I still have the problem 
of starting Pygrads.

You do not need a dual system. These instructions are for two separate computers on the same network.

You basically mount a ntfs drive from a windows system on your Linux system.

Have one of your IT Admin folks look at my instructions and help you.

Oscar,

"regrid2" used to be an external user-defined function, but now there 
are other regridding functions (think these regridding functions in 
GrADS v2 are User Defined Extensions as described at 
http://opengrads.org/doc/udxt/re/re.html#history, but I'm not totally 
clear on the technical term to use)...

To check on your user defined extensions...
look for a file like "udxt" in your installation directory,
or try "opengrads -h", then
"opengrads --ga2udxt"
or from the command line, try:
ga-> q udxt 
...

and check for "regrid2", "re2", "re_" or "re"...
if you have "re", you can check out the "re" documentation at: 
http://opengrads.org/doc/udxt/re/re.html

I'm not sure which of these is recommended (I'm using "re()";  in our 
GrADS version 2.0.a7.oga.3 udxt file, "regrid2()" is described as a 
"regrid2-like wrapper for re()"...)...

Hope this helps,
Chuck

Subject: [gradsusr] How to assign a 2-D array at many levels to a 3-D array
Message-ID: <001701caf3da$4603e180$d20ba480$@edu.tw>

I am more familiar with fortran program than grads script. In Fortran, it is
very easy to assign a 2-D array at many levels to a 3-D array. For example, 
   Do k=1,10
      Do i=....
       Do j=....
          Arr3(i,j,k)=arr2(i,j)
       Enddo
      Enddo
    Enddo

However, in Grads, I don't know if there is a similar way to do so. "Define"
seems not work in this situation. Could anybody help me out on this issue?
Thank you very much.

John, 

Many thanks. I am sorry that I didn't state my problem clearly. 

I ran the WRF on a server (Linux), then I downloaded the data files (for GrADs) onto my external hard drive through the network by using windows ftp. Then I deleted those data files on the server.  
Now I want to upload the data files onto my own laptop (Linux) to do GRADS analysis. But my external hard drive was formatted in ntfs. When I hook the external hard drive into my laptop through the USB slot, I can see the icon "Passport ... " of the external hard drive. But when I click on the hard drive icon, it pops up an error message window saying "the files are in ntfs... cannot be mounted..." . 

If there is no way to upload those ntfs files from the external hard drive to my Linux laptop, please also kindly let me know.

You do not need a dual system. These instructions are for two
separate computers on the same network.

 

You basically mount a ntfs drive from a windows system on your
Linux system.

 

Have one of your IT Admin folks look at my instructions and help
you.

John,



Many thanks! But I don't think my laptop has the dual system, it's only Red Hat

Go on to your windows box, create a user without admin, set an
Id/Passwd for it, share the folder (yourShaeName) with your data, and set
permissions to allow that new user to have read and write on it.

 

Go to your Linux box and install smbfs. Under Ubuntu it is
?sudo apt-get install smbfs?

 

Edit the /etc/fstab file on your Linux box and add a new line

//yourWindowsServerName/YourShareName  /mountDir 
cifs   username=Id,password=passwd 0 0

 

Make the /mountDir directory

 

Mount /mountDir

 

The names are not literal here; please change them to whatever
you want to name them.

Hi, 

Many thanks, especially to those who answered my previous question about
plotting multi-figures into one page. 

Another question: I have my harddrive formatted in windows (ntsf), but now I
want to download the files into my Linux laptop. 

Is there any way to convert the files into the format such that the Linux can
read?

Thank you Charles,

Yes, I have been using that option with grads 2.0.a7.oga.3, however, now I
want the same for grads 2.0.a8, but opengrads with this version is not
available yet...that's why I am trying to do it myself, by the way, I need
grads 2.0.a8 because with this version it's posible to draw shp files, and I
need these two features at the same time.

Hi,
I am new to the Grads. Now first thing is trying to find the right directory
for my data files and *.ctl file directory. How can I get into my data
directory in D drive while Grads is installed in C drive.
The sample file of *.ctl is in
C:\OpenGrADS\Contents\Resources\SampleDatasets. I could follow the tutorial
to run the sampledatasets. But I can not do anything with my own data.
Do I need to create three files at the first instant *.ctl, *.grb and *.gmp?
How to make later two files?
I noticed the user guides in http://grads.iges.org/grads/gadoc/users.html
However, I still need a hand to lead me go to the right position to where to
start with.
Many thanks.

Bo

Thanks very much, Teddy. They are very helpful.
I am trying to get ice data out in Greenland Sea. It seems I don't need to
create the three files, directly can get the plot and results from some
commands. I know Ferret, Grads seems a little like Ferret.
Cheers!

There's an example script in the documentation that shows you how to  
do this. You use 'q dbf' and parse the output to get the attribute  
value of each shape, then choose a color to draw that shape. In the  
example the value is retrieved from a separate file, but the 'q dbf'  
output it still parsed to get shape attributes, so you'll get the  
general idea.  --Jennifer

my data file folder which is in D drive, such as D:/seaice/data/, I tried to
open my nc  data file using sdfopen statement, it tells me that udunits(3):
couldn't open units darabase "D:/seaice/data/udunits.dat", no such file or

Hello,
unfortunately I am starting now with grads. at the moment I am not able to
display data from the bin file you sent me. I don't know why. Moreover I
am not able also to re-obtain that bin file by means of radar.f and I
cannot send you the complte data file because it is too big.
I am sorry.

Thank you in advance

Cinzia,

Edit the radar.f file you were sent by Alexandre and change the 4x5 array to fit the size of your big dataset.

Change the input name to the name of your input file, Alexandre used 'dbz.txt'.

This is not so much a GrADS issue as it is a knowledge of programming and building software.

After you change the array size to fit your dataset, then create the executable. e.g. gfortran -o dbz radar.f

Rerun the application, e.g. ./dbz

It will create the datafile dbz.bin and you can use the control file he sent.

Liping,

Since they are connected via the USB port you can still treat it like a mount.

Use 'sudo blkid' to identify the UUID of the device.

Sudo Edit the /etc/fstab file (make a backup first) and add a line at the bottom similar to your ext lines with a new mount point; however, the device will be ntfs and not ext3 or ext4.

Make a directory of the same name as your mount point.

mount /yourMountPoint

Some people use /media/usb1 to clearly identify it.  Use what you can remember easily.

Unmount it if you are going to disconnect the USB drive.

John,

Many thanks. I am sorry that I didn't state my problem clearly.

I ran the WRF on a server (Linux), then I downloaded the data files (for GrADs) onto my external hard drive through the network by using windows ftp. Then I deleted those data files on the server.
Now I want to upload the data files onto my own laptop (Linux) to do GRADS analysis. But my external hard drive was formatted in ntfs. When I hook the external hard drive into my laptop through the USB slot, I can see the icon "Passport ... " of the external hard drive. But when I click on the hard drive icon, it pops up an error message window saying "the files are in ntfs... cannot be mounted..." .

If there is no way to upload those ntfs files from the external hard drive to my Linux laptop, please also kindly let me know.

You do not need a dual system. These instructions are for two separate computers on the same network.

You basically mount a ntfs drive from a windows system on your Linux system.

Have one of your IT Admin folks look at my instructions and help you.

Bo,

GADDIR specifies the path to the directory containing font files, map outline data, udunits.dat, etc. These files are needed by grads for almost all its operations, and they should be included in the Opengrads packages. I'm not too familiar with Opengrads, but the windows version is supposed to be relocatable so it should not be necessary to change GADDIR. In particular, do not set GADDIR to the path to your own data. Instead, do something along these lines:

sdfopen d:/seaice/data/filename.nc

You don't need to install udunits as long as GADDIR is set properly.

arr3 10 99 arr3
endvars

When you open arr3.ctl, the variable 'arr3' will be a 3-D variable with the values of arr2 copied to all 10 vertical levels.

Subject: [gradsusr] How to assign a 2-D array at many levels to a 3-D array

I am more familiar with fortran program than grads script. In Fortran,
it is
very easy to assign a 2-D array at many levels to a 3-D array. For
example, Do k=1,10
Do i=....
Do j=....
Arr3(i,j,k)=arr2(i,j) Enddo
Enddo Enddo

However, in Grads, I don't know if there is a similar way to do so.
"Define" seems not work in this situation. Could anybody help me out on

Message-ID: <AANLkTinhv2RvHo0KLhBp2JLs-BLYdOLGu5ShQnzihb1F@mail.gmail.com>

Hello,
Has anyone used MODE before?  I want to view the objects that are output
from MODE in Grads by viewing the mode_......._obj.nc file that it produces
when it runs.  I know I can use ncview to view this file, but I want to use
it in Grads and use the maskout function to do some testing of the objects
compared to the raw precipitation fields I have.  I've tried using sdfopen
and xdfopen to open the file, but it always says "file  has no discernable x
coordinate."  Does anyone know how I can get this file to open in Grads?
Thanks.

Thank you, Erik. 
Sorry that I did not say it clearly. The 2-D arrays are at 10 different levels with different values. But, it is very easy to fix according to the idea you provided. However, I actually need to use the 3-D array for calculation right away in the same script. Do you know how to read it in right after I fwrite it out? Thank you again.

Hello jfj,

You could do this using the fwrite capability in grads:

'set gxout fwrite'
'set fwrite arr3.dat'
k=1
while (k<=10)

After you create the ctl file for your new 3-D variable, put in your script the line

'open arr3.ctl'

at any point after 'disable fwrite'. (It is important to disable (close) the fwrite file before you try to read the data in it.) You can then use the variable arr3 (or whatever you decide to name it) like any other grads data variable. Of course, when you open arr3.ctl, the new variable will be in a new data file, and grads will assign it a file number according to the number of files you currently have open. If it is the second file you have opened, you can access it using 'arr3.2' in expressions (keeping in mind the current default file and dimension environment and whether it is compatible with the dimension ranges specified in arr3.ctl), or you could 'set dfile 2', modify the dimension environment if necessary, and proceed from there.

Hello Alexandre,
my radar data file has this structure, as I already told you:

# Fields: z y x DBZ
# Units: km km km dBZ
1 -224.625 -224.625 35
1 -224.625 -223.875 28
1 -224.625 -223.125 20
1 -224.625 -222.375 20
1 -224.625 -221.625 18

They are related to a single radar scan (so only one time), but they have
20 z levels (from 1 km to 15.25 km every 0.75 km), 600 y points and 600 x
points (from -224.625 km to 224.625 km every 0.75 km). Both x and y are
obviously related to longitude and latitude.

I modified radar.f in order to account for my big dataset.
I modified your control file in the following way

dset ^0dbz.bin
title  Analysis DBZ
undef 	-32
xdef     600  linear -224.625 0.75
ydef     600  linear -224.625 0.75
zdef 	 20   levels
    15.25
    14.5
    13.75
    13
    12.25
    11.5
    10.75
    10
     9.25
     8.5
     7.75
     7
     6.25
     5.5
     4.75
     4
     3.25
     2.5
     1.75
     1
tdef     1  linear 22oct2005 1mn
vars 4
z	 0 999 z(km)
y	 0 999 y(km)
x	 0 999 x(km)
dbz 	20 999 DBZ
endvars

but I cannot see anything reasonable with grads. What am I wrong?
Thank again.
Cinzia

Thanks for the answers to my previous question. The "parea" and "vpage" commands work, but I have to specify the picture size every time. I want a more robotic (generic) approach, if possible. 
The GrADS template data descriptor is a wonderful idea! But does it only do aggregating or concatenating? I want to manipulate the fields before I plot out the hovmollers: 
First I plot the hovmoller using data from file 1 for Aug10-15: 
'set yflip on'
'set lev 1000'
'set tlsupp year'
'set t 2 48'
'set lat 15'
'set gxout shaded'
'set grads off'
'd ave(olr.1,lat=5,lat=25)'
Then I want to add the hovmoller plot using data from file 1 and file 2 for Aug15-20: 
'set t 49 80'
'd ave((olr.1+olr.2)/2,lat=5,lat=25)'

Question: Is it possible that I write the fields (olr) from different data files (with different ctl files) into one data file with one ctl file? 

Thanks!

Liping

Liping,
You could try templating the files using CHSUB:

Subject: [gradsusr] time interval too short
Message-ID: <4BF2DADF.4010407@hawaii.edu>


I have a netCDF data set that I can read off local disk using the new 
release of GrADS (2.0.a8), but I get an error when trying to read the 
same data set via OPeNDAP.  The error is:

gadsdf: Tme unit has too small an increment (min. 1 minute).

The actual increment is 4 minutes, and ncdump shows time as:

time:units = "minutes since 2008-01-01 00:00:00";

The previous versions of GrADS (2.0.a6 and a7) had a different problem 
reading the same data set via OPeNDAP:

gaopnc error: nc_open failed to open file 
http://oos.soest.hawaii.edu/thredds/dodsC/hioos/nss/ns01agg
read_metadata: gaopnc failed.

So, it seems va8 solved the metadata problem but might have a new one.  
Note that both versions can read the data set without problem off local 
disk, it's only when accessing via OPeNDAP.

Finally, grads-2.0.a7.oga.2 can also read off local disk, but has yet a 
different error reading via OPeNDAP:
 Unknown error 1002
SDF Error: nc_get_vara_double failed to read coordinate axis value
gadsdf: Error reading second time values in SDF file.

All versions are running on a linux EL5 machine (x86_64) machine.

Hi,

I am looking to plot ocean current data as a time series plot.  I want various sub-surface levels plotted on the y-axis and the time steps on the X-axis.  Can someone tell me how, and if, this can be done with GrADS?

Thanks

Hi Brian,

have a look at how the grads-binary files are organized.
http://grads.iges.org/grads/gadoc/aboutgriddeddata.html

<http://grads.iges.org/grads/gadoc/aboutgriddeddata.html>The loop goes first
over the x, y,z,VARS, and then time. So, you have to order your data in the
right order:

1.level, 1.time
1.level, 2.time
...
1.level, last time
2.level, 1.time
2.level, 2.time
...


It seems to me more natural to use the z-coordinate for the sub-surface
levels, and the time axis for the time, but I guess you have some plans with
your setup.

Regards,
Heiner

Hi, 

I know this is a little off topic, but am having problems trying to resolve a problem. 



I'm receiving the following error meessage out of wgrib2 



** Fatal Errror ** rd_grib2_msg? Missing end section ('7777') 



Am receiving this error when concatonating?multiple?time step gribs from the ww3 model.

Hi
I am trying to make a rectangle over the region 65 deg to 75 deg east and
equator to 10 deg north.
As per instructions in the grads document first of all i made set line 1 1 1
then use draw rec 0 65 10 75 command. but there is no rectangle drawn on the
plot.

In the draw command xlo ylo xhi yhi corresponds to grid point or waht else.

Hi,

it is actually a little confusing. The draw command uses the coordinates of
your drawing window. Those coordinates range from 0 to 8.5 and 0 to 11 inch.
The coordinates that you were using are the world coordinates. Use the
function "q w2xy" to convert from world to xy coordinates, eg. for 65 deg
east and 10 deg north
q w2xy 65 10

Heiner

Hi Sushant
I send you a little example that allow to draw a rectangle using world
coordinates, so you can change the size or change slightly the geographic
region selected for your plot and the rectangle will be "anchored" to its
geographic position. This small code shoul by used in a *.gs script.
Best regards.

Anna

You may want to think about the architecture as 20 600x600 grids. So, instead of opening the binary file with LRECL=4, open it with a record length of 36000.

Set up a real array of A(600,600,20), initialize it to -999, then read in all the data, compute the Z level 1:20 corresponding to your 20 levels, compute the (ipos,jpos) given the input (km,km) units, and set the value equal to the dBZ.

Then write out each of the records in a do loop like
IREC=1
DO I=1,20
WRITE(15,REC=IREC) ((A(J,K,I),J=1,600),K=1,600)
IREC=IREC+1
ENDDO

Your control file becomes much simpler and you have 20 layers of data to plot.

Think about it and if you want help, I can help you later with the coding, but not now..am working on another project.

Subject: Re: [gradsusr] Creating data files

Hello Alexandre,
my radar data file has this structure, as I already told you:

# Fields: z y x DBZ
# Units: km km km dBZ
1 -224.625 -224.625 35
1 -224.625 -223.875 28
1 -224.625 -223.125 20
1 -224.625 -222.375 20
1 -224.625 -221.625 18

They are related to a single radar scan (so only one time), but they have
20 z levels (from 1 km to 15.25 km every 0.75 km), 600 y points and 600 x
points (from -224.625 km to 224.625 km every 0.75 km). Both x and y are
obviously related to longitude and latitude.

I modified radar.f in order to account for my big dataset.
I modified your control file in the following way

dset ^0dbz.bin
title  Analysis DBZ
undef 	-32
xdef     600  linear -224.625 0.75
ydef     600  linear -224.625 0.75

    11.5
    10.75
    10
     9.25
     8.5
     7.75

     6.25

tdef     1  linear 22oct2005 1mn
vars 4
z	 0 999 z(km)
y	 0 999 y(km)
x	 0 999 x(km)
dbz 	20 999 DBZ
endvars

but I cannot see anything reasonable with grads. What am I wrong?
Thank again.

Message-ID: <1E8644A2BCBD5E4A9967E1E00D5D4C73B6D28CF866@NDMSSCC05.ndc.nasa.gov>

Hello grads users,

I am using GrADS to output wrf data.  In the interpolation tool ARWpost, I interpolated the variables to every 25 hPa.  When I attempt to plot a vertical profile with the following script:

Reint
C
Set display color white
Clear
Set LON 15
Set LAT -5
Set LEV 1000 100
Set t 5
Set vrange -1e-9 1e-8
Print /Users/jonathanwsmith/Desktop/ozone_vert_prof.gif

 I get the graph that I have attached I end up with several straight lines going left to right and data points that are not connected to each other.  How do I connect the data with grads?

Jonathan,

the data. Try to view the variable with "set gxout stat" command to
determine the upper and low limits of the variable first.

Dear all,
I have spatially distributed daily rainfall data series.
I would like to prepare area averaged filtered rainfall series which retains information on 10-60 day mode.

Can you please suggest me how can I prepare filtered rainfall series using GrADS script.

Thanks.

We have recently installed grads2 on our Linux box.  We have been using grads 1.94, which is also still installed.  Grads2 is finding my script files, but not the user-defined functions.  The latter still work with grads 1.94, but not grads 2.  Can anyone offer any suggestions on what I still need to do?

Thanks in advance.

Dear users,

In grads, we have many conversions like xy2w, xy2gr, w2xy, w2gr, gr2w,
gr2xy, ll2xy, pp2xy.

What is the difference between these different co-ordinate systems like,
world coordinates, grid coordinates, XY coordinates, LON/LAt coordinates and
page coordinates ?

Can anyone having idea about these explain me?

thanks and regards,

Hi Subhadeep,
One example of w2xy (world coordinate to xy coordinate):

In case you want to draw some line and some point at a particular lat/lon of your figure, you need to know the XY coordinate for that grid point as grads doesn't take the direct lat/lon value. So by defining w2xy, your lat/lon will convert to XY coordinate, which you can use in GrADS plot.
Similarly you can follow for others.

>Dear users,

In grads, we have many conversions like xy2w, xy2gr, w2xy, w2gr, gr2w, gr2xy, ll2xy, pp2xy.

What is the difference between these different co-ordinate systems like, world coordinates, grid coordinates, XY coordinates, LON/LAt coordinates and page coordinates ? 


Can anyone having idea about these explain me?

thanks and regards,

Subhadeep

Subject: [gradsusr] Help needed in getting annual mean from time series data
Message-ID: <AANLkTinoU103IVPSK-1dMnKuWSatlDv7yeY8EGzBMf6f@mail.gmail.com>

Dear Grads users,
I am a beginner in GrADS.
I have a multi-year time series data. I want to get the annual mean in this
data.

Please see that from the following I can get monthly time series plot, and
it is working fine.

'set lon 30'
'set lat 5'

'set t 2 302'

*------------------------
*Monthly time series
*------------------------
'define sstmonth=aave(sst.1,lon=30,lon=78,lat=5,lat=31)'

'set gxout line'
'set cmark 4'
'set grads off'
'set ccolor 9'
'd sstmonth'

In the same plot, I want to have one more curve showing the annual mean.
I mean 26 annual mean values for the 26 years.

I don't know how to do this.

I will highly appreciate if someone can help me in this.

Thanks,

Sudev

Message-ID: <AANLkTinT7Vdky6EwJ5hO4Azwiji13WjAX7b945cUH9g3@mail.gmail.com>

Hello,

I just ran into a problem regarding Grads computation speed. I have
set up a WRF model over Europe and extract surface parameters for
about 4-5000 points in the model for 72 timesteps. Now I tried another
WRF version which produces different output files, and the computation
speed for my Grads tasks for the new model is much much slower than
before. You can find the first lines of my control files below.

Using my old model, I could run my complete Grads tasks in about 90
minutes. Using the new setup, this takes forever to complete (had to
skip this as it took too long, think it should be around 180 minutes
or so), of course on the same machine. The main difference must be in
the Gribfiles I am using.

Can anyone explain why this might be happening? Which Gribfile
settings (version, projection etc.) are the best usable ones for
Grads? And finally: how can I improve computation speed for my new
model?

Thank you for your answer!

Best regards,
Jonas Kaufmann

Jonas, you need to tell us the version of grads...  so the old data is
binary and the new data grib? ciao mike

Hello Michael,

I tried on two machines with the same results. One is running Grads
Version 2.0.a1.oga.1, the other one is OpenGrads Version 2.0.a7.oga.3.
In both cases using the new version of my model was significantly
slower than the old one.

The old model used ARWpost as WRF postprocessor, the new one uses
wrfpost. Both outputs are only customized in terms of available fields
in the Grib file, all other options should be the default ones.

Thank you for your help!

Best regards,
Jonas Kaufmann

Hello,

there is a big difference in computation time between grib1 and grib2  
when using grads. Perhaps you have to look at the grib file types...

Mike,
Thanks very much.  I would conclude, then, that we would need to reinstall grads2 using the opengrads version.  (We had installed 2.0a8 from the iges.org web page.)  And first uninstall the 2.0a8 version.  Is that correct?
Tim

Subject: [gradsusr] Help needed in getting annual mean from time series data
Message-ID: <AANLkTinFuwwcIibO5N_o2SPK17WG2Nw3p4US3NbHue2C@mail.gmail.com>

Dear Grads users,
I am a beginner in GrADS.
I have a multi-year time series data. I want to get the annual mean in this
data.

Please see that from the following I can get monthly time series plot, and
it is working fine.

'set lon 30'
'set lat 5'

'set t 2 302'

*------------------------
*Monthly time series
*------------------------
'define sstmonth=aave(sst.1,lon=30,
lon=78,lat=5,lat=31)'

'set gxout line'
'set cmark 4'
'set grads off'
'set ccolor 9'
'd sstmonth'

In the same plot, I want to have one more curve showing the annual mean.
I mean 26 annual mean values for the 26 years.

I don't know how to do this.

I will highly appreciate if someone can help me in this.

Thanks,

Sudev

Tim,

you don't need to uninstall 2.0a8, just put opengrads in a different
location.  the only significant difference is that opengrads has an
interface for extensions...

ciao mike

Dear User,
I have spatially distributed daily rainfall data series.
I would like to prepare area averaged filtered rainfall series which retains information on 10-60 day mode.

Can you please suggest me how can I prepare filtered rainfall series using GrADS script.

Thanks.

Subject: [gradsusr] How to get a monthly & yearly time series plot correctly?
Message-ID: <AANLkTild9knuPwumnmZvPslwFg_nojbS9O3c6rNz_hOg@mail.gmail.com>

Dear Grads users,
I am a very beginner in GrADS.

I have a multi-year SST data. I want to get a time series monthly and annual
mean plot of this data
in a specified region in the same figure, keeping same x-axis (time) and
y-axis (SST).

Please see below the code I am having, I also attach the figure I am getting
out of it.
The annual mean value is found to be constant for all the 25 years I
considered.
Definitely some mistake I am making in the code, which I am not able to
identify.

Can somebody please help me the correct way of doing it?

Why is this not 'set t 1 302' ?

Try this after you have defined sstmon:

'set t 1 12'
'sstann = ave(sstmonth,t+0,t=302,12)'
'modify sstann seasonal'

Subject: [gradsusr] NetCDF file trouble w/ GrADS
Message-ID: <f79b4e1a46924ac2.4bfacc7f@noaa.gov>

GrADS users,

I am fairly new to GrADS and continue to have problems with getting output from my NetCDF file. I have attached the NetCDF file and data descriptor file I have created.

GrADS allows me to open the .ctl file, but only plots constant values of zero when i run the command 'd surf'.

Any help here would be very much appreciated.

*Sorry for sending a large file.

Alex Gibbs

To: dasilva at alum.mit.edu



 hello

dear i am converting daily precipitaion data (aphrodite) form 1961 to 2007
from ctl type to nc(netcdf) type , i have done it but now i want to find the
monthly total from 1961-2007 using lats4d
 but i am not understading how to do?
the script that i have wrtten is as :

'reinit'
'open data-aphd\APHRO_PAK_005deg_V0902.1961-2007/APHRO_PAK_005deg_V0902.ctl'
ti=1
tf=ti+30
y=1961
while (y<=2007)
while (ti<=16832)
'set t 'ti
'lats4d -v -i
data-aphd\APHRO_PAK_005deg_V0902.1961-2007/APHRO_PAK_005deg_V0902.ctl -ftype
ctl -o waheed/JAN'y' -func sum(precip,t='ti',t='tf')'
ti=ti+365
'set t 'ti
'q time'
say result
res=subwrd(result,3)
yf=substr(res,9,4)
if (y=yf)

Hello,

which one should be faster then, grib1 or grib2? Does the projection
of the file have an influence on the computation speed?

Dear Madam,
Thanks for your reply.
In fact I sent my question yesterday to the GrADS user group, but didn't get
any reply so far.
I still could not resolve it.

I found that there is no keyword search option in the Grads Forum archive.
Could you please tell me if there is any such?

The data file link is given below:

http://apdrc.soest.hawaii.edu/dchart/index.html?cid=AAAAJA@@

Please also see my yesterday's email. if you have any further suggestion, I
will highly appreciate.
--------------------------------------------------------------

I have a multi-year SST data. I want to get a time series monthly and annual
mean plot of this data
in a specified region in the same figure, keeping same x-axis (time) and
y-axis (SST).

Please see below the code I am having, I also attach the figure I am getting
out of it.
The annual mean value is found to be constant for all the 25 years I
considered.
Definitely some mistake I am making in the code, which I am not able to
identify.

Can somebody please help me the correct way of doing it?

Subject: [gradsusr] plotting vertical wind profiles
Message-ID: <0E42BC94-4A89-4E16-84FD-B6189EFB1E49@umd.umich.edu>

I would like to plot vertical wind profiles that display both the wind speed and the wind direction at select points.   In another program (i.e., Gempak) I was able to plot a line graph of wind speed in the vertical on the left and wind barbs at selected elevations denoting wind direction on the right in the same graph.  In Grads, I am able to plot wind speed, but I have not found a way to display a vertical profile of wind direction using wind barbs or wind vectors, etc.   I would appreciate any advice. 

Thanks,
Claudia

Not sure if this is of use, but I beleive if you dump your gribs to binary (using wgrib2) before hand, and then run your scripts againt the binary files, it will be even faster (than grib1).? Of course, it might take a few minutes to do the conversion to binary. ? 


Thanks, 
Mark

Claudia,

Not sure if I understand what you want to do, but there is a SkewT/LogP 
Function for GrADS at http://moe.met.fsu.edu/~rhart/software/skew.html
with a sample image: http://moe.met.fsu.edu/~rhart/software/skew.html#sample

Hope this helps,
Chuck

In another program (i.e., Gempak) I was able to plot a line graph of wind speed in the vertical on the left and wind barbs at selected elevations denoting wind direction on the right in the same graph.  In Grads, I am able to plot wind speed, but I have not found a way to display a vertical profile of wind direction using wind barbs or wind vectors, etc.   I would appreciate any advice.

NCEP distributes the grib2 forecasts using jpeg2000 packing which is pretty
good at compression but very slow.  Grib1 one uses simple packing which
is fast.  Complex packing combines speed with compression.

Rather than convert a grib2 file into binary, I would convert the file 
to complex3 packing by

   wgrib2 in.grb -set_grib_type complex3 -grib_out out.grb

Hello everyone
I want plotting the maximum and minimum temperature,

The network (and the Grads tutorial) I did not find any reference.


Could someone help me?

Claudia,
           I use the following script for a specific station(lat/lon) for
 27 levels and time t=1 to t=37.I have used three types of displays viz
speed in knots, m/sec and skipping some values.
You  may change these values to suit your requirement.Data file used by me
is 05may06_nonocc.ctl
Hope it serves your purpose.
Anil

'reinit'
'open 05may06_nonocc.ctl'
'set lat 30.15'
'set lon 74.45'
'set gxout barb'

Subject: [gradsusr] compare WRF output with NCEP FNL reanalysis
Message-ID: <676243.45374.qm@web36807.mail.mud.yahoo.com>





Hi there,

I am new in GraDS and don?t know how can I compare WRF
output with NCEP FNL reanalysis. It seems there are several steps to be done. First
I started with ARWpost to convert WRF output to GrADS readable output. It is worked
fine and now I have to find a way to overlay the reanalysis field. I used g2ctl
to create controls files (ctl) for the grib2 NCEP FNL reanalysis and gripmap to
create the index files but it seems not enough since the reanalysis domain is
much larger and has coarse resolution than the model domain and model output
resolution. How should I proceed with the last two steps in GrADS? some examples ? 

Thank you.

CK

Subject: [gradsusr] Need help in converting ctl file to netcdf format using
	lats4d
Message-ID: <AANLkTine0dTSGURtJpuQUfPkE9_olkl3KBvvpxh-kksz@mail.gmail.com>

dear all

i am trying to find the sum of month January for the years 1961 and 1962 and
make a file of each in netcdf format( i.e: the time step is one for
january1961 and one for 1962)

For this i used the script Lats4d but it does not write it as i want!

Parameter is precipitation

it actually writs the NC file for the the total time step 720 which is a
daily file but showing the sum of first month(1961) for all time values i.e.
the value is same for t=1 and t=720.


i have attached the screen shot and the script file with this mail

kindly help me


thanking you all in advance

regards

I could not get the problem in your script. Did you get any error message?

see the link
http://sites.google.com/site/modellingearth/chapters/software-tools-list/sample-codes/grads-code

There are two scripts related (may not be exactly same) to your requirement.

1. text_out_nonuniform_lat_grid.gs
2. matrix_gridded_text_ out.gs

refer these scripts and write your own script to solve your problem. If you
get any specific error message, please give the details.

Subject: [gradsusr] mfhilo still broken?
Message-ID: <BAY117-W276C51D91618DDD7C2C54EF9EC0@phx.gbl>


Hi,
I need to use mfhilo (in opengrads v2.0.a7.oga.3.1 on linux, built from cvs source), 
but last I remember, mike fiorino's user extension package was broken.
is this still the case? whats the status with this extension?  
are there any updates on when this will be available?

thanks
p.r.

Subject: [gradsusr] searching gradsusr
Message-ID: <791072EB-562D-45A9-90B8-018AA1E3B4BA@berkeley.edu>

Hi,

This might be a silly question, but does anyone know how to search the entire gradsusr archive: http://gradsusr.org/pipermail/gradsusr/?

I can only see how to search for threads in specific months on the webpage. Maybe there is another way?

Thanks much,

Andrew

Subject: [gradsusr] problem with 3D figure
Message-ID: <190005.45531.qm@web55507.mail.re4.yahoo.com>

Hi?I met some problem in displaying 3D variables in GrADS. My netcdf file included 15 variables, some variables are 2D while some are 3D, when I type ?q file?, the Z size is 1, let?s say I have dep=15 in my 3D variables, so how I display the 3D variables where dep=12?
Thanks for any information.
