Hi Arlindo, 

Thanks so much for getting this new release out.? Am looking forward to using it but am having some problems. 



Downloaded the superpack zip, copied it to my C drive on a Win XP machine, unzipped it, set the path to? the following directory and tried to run it in batch mode but received?errors: 

C:\Program Files\opengrads\Contents\Cygwin\Versions\2.0.a7.oga.1\i686\

Interesting, but it builds the first image in the a series fine, but stackdumps trying to build the second image (i.e. Time Period 3). 



So it doesn't seem to be a pathing issue. Also fails with similar results using other scripts and other options. 



These same scripts works fine in Grads 1.8 and 1.9 through the mutiple?series of images. 



Any ideas? 


Thanks, 
Mark

Dear Windows Users, 


?? We have upload to sourceforge version? 2.0.a7.oga.1 ?the Win32? Superpack : 


https://sourceforge.net/projects/opengrads/files/grads2-windows/ 



(See my previous posting announcing a similar release for Linux to learn about what is new in this release --- the Windows build has? all ?the features of the Linux version). ? 


If you have the necessary privileges to install software on your computer I recoomend the Windows installer ( *-win32_superpack.exe ) which will optionally set your path and create an entry in your? [Start] ?menu, placing links on your Desktop. The? [Start] ?menu entry now also includes links to the bundled HTML documentation, with Tutorial, User's Guide and Command Index (from COLA), and "manual pages" for the OpenGrADS extensions. Try out the MERRA and NOMADS Browsers for a (live) graphical user interface to the MERRA reanalysis and NOAA forecast data (GFS, NAM, RUC, Wave) through OpenDAP (a network connection is required). 


?? As before, we are also including a? *-win32_superpack.zip? package ? for those users who do not have the admin privileges to install software on their Windows boxes. ?? ?The contents are exactly the same as the? *-win32_pack.exe ?package and are meant to be relocatable: copy the OpenGrADS directory to a USB mem stick and take it on the road with you. The VBscript wrappers at the top remain experimental; I'd appreciate any feedback from people who actually know VBscripting.? 


?? For those experienced cygwin users preferring a light weight distribution (and willing to set the necessary environment variables), we are again including tarballs with the binaries and extensions. 


??This version has been verified to work on Windows 7 RC (Build 7100). 


??Please any me know of any issues. 


??Enjoy! 


?? ? Arlindo

Does it work with the OpenGrADS Bundle v2.0.a5? Besides the changes in grads
proper, I changed the build environment going from a5 to a7 for Windows 7.

Hi Eric,

Thank you for your correction. I changed the gs file, and got the binary file with size of 140 bytes. After grads scanning the ctl file, it still showed: can not open the binary file. I am stocked there.

Hi Emily,

What is the size of the binary file? It should be 7*5*4=140 bytes. If it's not that size, check your script for any bugs I may have missed. If it is 140 bytes, then I don't know why grads can't open the binary file. In fact, even if the file exists but has a size of 0 bytes, grads should open it. Make sure the file is actually being created. If it doesn't exist, I have no idea why.

Best regards,
Eric

Hi Emily,

fwrite writes data in binary format, not GRIB. Remove the line 'DTYPE grib' from the ctl file. You also have two bugs in your script:

while (t0<222)

should be:

while (t0<=222)

and also

while (h>850)

should be:

while (h>=850)

Using < and >, the values for t=222 and lev=850 will not be written because the last iteration of the loops will be for t=221 and lev=875.

I also don't see any entry for the v wind in your ctl file for the netcdf data. If it is not in the dataset, your wind speed calculation will fail because of missing v wind.

 From the doc page http://iges.org/grads/gadoc/SDFdescriptorfile.html:
  The 'sdfopen' and 'xdfopen' interfaces do not support the HDF5
format. The 'open' interface is the only way to read HDF5 files.

The biggest difference between descriptor files for HDF5 and NetCDF
are in the variable declaration -- the varnames have to be aliased.
 From the doc page http://iges.org/grads/gadoc/descriptorfile.html:
   For dtype hdf5_grid, the SDF_varname may be particularly long since
it must contain the names of all the nested groups (separated by "/")
to which the data set belongs. For example: /HDFEOS/GRIDS/
EarthSurfaceReflectanceClimatology/Data~Fields/
MonthlySurfaceReflectance=>msr

Hello,
I'm trying to read what I think is a very complex bufr file.
My ctl file looks like this:
DSET ^layermean_bufr.20090921.18.nh
TITLE AMV Layer Mean Data
DTYPE bufr
UNDEF -999.0
TVAR yr 4,1 mo 4,2 dy 4,3 hr 4,4

VARS 3
amvlon 1 6,1 AMV Longitude
amvlat 1 5,1 AMV Latitude
amvpre 1 7,4 AMV Assigned Pressure
ENDVARS

When I start grads I type:
open bufr.ctl
d amvpre;
I then get:
warning: ignoring unsupported operator F=2 X=22 Y=0
warning: ignoring unsupported operator F=2 X=37 Y=0
warning: ignoring unsupported operator F=2 X=22 Y=0

warning: ignoring unsupported operator F=2 X=37 Y=0
warning: ignoring unsupported operator F=2 X=22 Y=0
 that repeates over and over again until grads crashes.

When I look at the bufrscan for the F=2 X=22,36,37 I see:
2 22 000  (operator)
2 36 000  (operator)
2 37 000  (operator)

Any thoughts on what's going on?

Hi, Howard --
The warnings may not be related to the cause of the crash. Can you
send me (not gradsusr) a copy of your bufr file so I can do some
testing on my own?

Message-ID: <FRI.2.OCT.2009.145111.0500.>

Dear users,

I am a beginner of GRADS, so I have lots of questions.
One of them is that I want to save a variable (or variables) to an ASCII
file.
I read that fwrite would work, but I don't know how to use it.

I define a variable named 'wind' as below.

define wind = ave(mag(uwind,vwind),t+0,t=360,12)

I want to save the variable 'wind' to ASCII.
I just used 'set fwrite' command, but I don't see any new file in my
directory.

Anybody can help me?

Wansang,
It has been my experience in the past that fwrite only works in script mode and not during command line execution. Have you tried using fwrite in a script?
Hope this helps,

Thank you, Teddy,

Do I have to use fwrite after I made a defined variable or before?
Do you have any simple example that i can use for my data?

I thought fwrite was for binary files.
 
Anyway I just use something like
 
MyFile = "MyFileName"
'set gxout print'
'set prnopts %6.1f 17'  (these are just examples .. change to whatever
format with however many values per line you want ..)
'd  wind'
rc = write(MyFile, result)
 
 
That will put your ascii values in the file "MyFileName".  There will be
the 2 grads header lines before the data you'll have to strip out.
There will be 17 values per lines, since that was what was specified in
the prnopts.  It probably makes more sense to set that equal to the
number of elements along X.

I wish to make 3-D plot for the wind, in order to see the structure of the
jet. Whether it is possible in grads.
Since i know that we can only plot it in 2-D by keeping latitude or
longitude constant.

Is there any solution on it?

HDF-EOS files are nothing more than HDF-4 files with additional metadata
added.  Format is not the issue here since GrADS can read HDF-4. The main
problem is that these files are not CF-1 (COARDS) compliant. For some Level
3 files, quantities are defined on a global 1x1 grid and a Data Descriptor
File (DDF)) can be written and the file opened with "xdfopen". However, most
Level 2 files are defined on swaths and such data structure is not currently
supported by GrADS. (I believe COLA has plans for supporting swath data in
the future, Jennifer may want to comment on it.)

   I have toyed with the idea of writing a GrADS extension for dealing with
swath data, but ended up using pyhdf in python for accessing such datasets.
On other situations, such as for EOS aerosol data (MODIS/MISR/OMI/PARASOL) I
have created my own grads readable version of datasets on the 1/4 deg GEOS-5
grid. Some of these are available on-line:

                       http://opendap.nccs.nasa.gov:9090/dods/AeroObs

  Good Luck,

This build should support all the PDEF options of grads v2.0.a5. But one

Sorry, this is a known issue on my to do list but it will have to wait until
we port LATS to v2 (as an opengrads extension.)

Dear All,

I am new to GrADS and I have a favour to ask.
I have monthly mean carbon monoxide ASCII data from ground-based measurements for the period 2000-2008. I am intend to detrend and deseasonalise data to look at trend in the data and also wish to calculate 12-month running average.

Does anyone have GrADS script to do these analysis?

Thank you very much in adv.

Dear Users,

I am a new to Grads.
I want to make a script file to save variables to a ASCII (*.txt) file.
Do I write a script in Grads directly or in a software like notepad.

And how I start to write it?
I think I'm really lost.
Please, teach me from the first step.

Somebody help me!

Hey,

you need to write plain text file with software like notepad. In that
file, you put the same commands that you put in grads command prompt,
just they need to be between these characters: ' '

For example, if you wish to plot temperature from command prompt, you
will give this command:
d tmp2m

In grads script, that should read:
'd tmp2m'

That's almost all, but there are some differences between command line
and scipting commands, and also, of course, in scripts you can do lot
more things like creating loops and using lot more tools (for example
defining custom functions), that you cannot do on command line.

Hope this helps. Also, please, read user manual here:
http://www.iges.org/grads/gadoc/users.html

And check some sample scripts to see how they work, for example:
http://www.iges.org/grads/gadoc/library.html

Bye, Ivan

Should the first line have 'function' command like 'function test (args)'?
Is there any command to finish script file?

Subject: Script file to make wind data and save it to ASCII
Message-ID: <MON.5.OCT.2009.155706.0500.>

Dear Users,

It is hard for me to make a right script file.
Some of the users has helped me, thanks, but i still don't understand.

My data has two wind data;
ugrd10m: u wind at 10m (monthly)
vgrd10m: v wind at 10m (monthly)

I want to make a script file that calculates the magnitude of wind
(mag(u,v)) of each month at a point and save it to ASCII.
Here is the script file I made, but it doesn't work as expected.
Any of you guys can correct errors in my script file?

========================
*Script Save as ASCII

'set grads off'
'set lon -123.93'
'set lat 45.67'
'set t 1 12'
'define wind=ave(mag(ugrd10m,vgrd10m),t+0,t=360,12)'
'modify wind seasonal'
'set gxout fwrite'
'set fwrite e:/research/climatedata/grads/data/wind'
'say 'ok''
==========================
Thanks,

Wansang

"set grads off".

with grads 1.9 and earlier versions the command "set grads off" inhibits
both GrADS:COLA/IGES and date ...

notice that "set grads off" command has to be repeated before each
"display". A common trick is to use "set imprun setgradsoff.gs" where
setgradsoff.gs is a simple script with "set grads off"

hoping it could help

All,
   I just refreshed the binaries for the OpenGrADS Bundle, now at version *
2.0.a7.oga.2*. This patch fix an important bug that caused "printim" to
crash at odd places. It is strongly recommended that you replace the
previous v2.0.a7.oga.1 installation. This bug bfixes affects all versions:
Linux, Mac OS X, FreeBSD and Windows.

   https://sourceforge.net/projects/opengrads/files/grads2/2.0.a7.oga.2/

Notice that this bug fix only affect the OpenGrADS release; no such bug
exists in the COLA releases.

All,
   I just refreshed the binaries for the Win32 Superpack OpenGrADS Bundle,
now at version *2.0.a7.oga.2*. This patch fix an important bug that caused
"printim" to crash at odd places. It is strongly recommended that you
replace the previous v2.0.a7.oga.1 installation. This bug fix affects all
versions: Linux, Mac OS X, FreeBSD and Windows.


https://sourceforge.net/projects/opengrads/files/grads2-windows/2.0.a7.oga.2/

Notice that this bug fix only affect the OpenGrADS release; no such bug
exists in the COLA releases.

Ravi,

Please find attached a GrADS script pptn_pentad.gs (and called "pause"
script function) which defines and plots 5-month precipitation averages
two ways... Please let me know if you have any questions about them.

Hope it helps,
Chuck

You might want to use NCO:

This is not a GrADS solution, though.

Hi,
You need to define first the levels and colors and then only use the cbar.
SET CLEVS ...
SET CCOLS ...

May be the attached script which plots four maps will be helpful.

Dear Sir/Madam,

I have a gridded data and I can plot the variables.
I want to get the Data at one Particular Latitude and Longitude (ie) for a station.
When I give 'set lat 12.42' it is taking at 12N as I have 1 degree data.

So, I request you to suggest me to get an interpolated value to a particular
lat/long (Station) from the Gridded data.

Thanking you

Hello,
   I believe what you can use is the gr2stn() function built into Grads
(more info http://www.iges.org/GRADS/GADOC/gradfuncgr2stn.html).
Essentially you'll type into the Grads command line: gr2stn(grid variable,
lon, lat) and it will output a station value for you.

If you can let grads open the binary data with a .ctl
file you should be able to use a grads-based tool
"lats4d" to convert it to netcdf.  See

http://opengrads.org/wiki/index.php?title=Lats4D

about the tool.  I had used grads version 1.10r2 for
a similar task.

Hi
Yes My friend of course. First you must make sure your Grads is version 2
above, because "sdfwrite" and "ncks (is under linux)" commands are under
version 2 above. For "ncks" make sure working , anyway you can install NCO
(Netcdf Operator) over your machine. Then
for convert binary to netcdf, first you must write a  ".ctl" file as follow:

dset ^EMP.dat
title evaporation mines prescripton
undef -9999
xdef 360 linear 360 1
ydef 180 linear 180 1
zdef 1 levels 0
tdef 12 linear 05z16jan1960 1mo
vars 1
EMP 0 1 emp
endvars

AND Script for convert as follow:

'reinit'
'open /home/.../binary2netcdf.ctl'
'set lon 0 360'
'set lat 180 359'
'set lev 0 0'
'set t 1 last'
'set e 1 last'
'define emp=var'
'set sdfwrite /home/.../data.nc'
'sdfwrite emp'

Please let me know.

But still I cannot get clear idea how to use gr2stn function in GrADS.
I fixed latitude, longitude and varied the time dimension.
and I gave? a command

d gr2stn(u,83.14,17.42)
It gives the error like "Invalid Stn Data Dimension Environment".

I request you to kindly suggest me to solve the problem.
I will be so thankful for your help.

hii daryabor

    yahh i'm sure i opened thru >>gradsc and the .ctl and data path was ok.
Now it is working fine after reducing the no. of variables from 20 to 10,
also the size reduces from 3GB to 1GB. I think it was the problem of such a
large file size or it depends on mechine memory.

thanks

Don't force the list members to download a file in order to help you.
Please include in your post the output from "ncdump -c" then we will
know what's in it without having to download anything. This link
points to a table full of different files, there's no way to know
which one you want to read.

> I have also attached the decriptor file that I have created to use
> the open or xdfopen command
The descriptor file was helpful -- it allowed me to figure out which
file to download, except the file name in your descriptor
(pr_A1.200101-220012.nc) does not exist on the server. I did find a
file called pr_A1.200101-210012.nc and will assume your descriptor has
a typo in it.

The easiest way to read this IPCC file is to use xdfopen. All you need
to do is properly describe the time axis, the rest of the metadata in
the file GrADS can interpret without any help. Your descriptor file
for xdfopen should look like this:
dset ^pr_A1.200101-210012.nc
tdef time 1200 linear 1jan2001 1mo

In-Reply-To: <fba0b0c57e44.4ac9d39e@hawaii.edu>
Message-ID: <FRI.9.OCT.2009.131616.0400.>

If you are using GrADS version 2.0.a3 or higher, you can use sdfwrite
to create a netcdf file. It's very straightforward: set the dimension
environment, define your variable, use 'set sdfwrite' to set the
output file name, then 'sdfwrite <variablename>'. Please read the
documentation:
http://iges.org/grads/gadoc/gradcomdsdfwrite.html. If you want to
write out more than one variable, you have to write out separate files
with GrADS, then concatenate them together using the NetCDF Operator
'ncks', which is a separate utility not distributed with GrADS.

If you are using GrADS 1.9 or earlier, then use lats4d.gs to create
netcdf output.

GrADS does not do any ftp, you will need to transfer the files yourself,
ahead of time. On many operating system you can setup a FTP file system in
while you associate a local folder with a ftp address (Windows does by
default, on Mac OS X install MacFUSE, on Linux install FUSE.) A FTP file
system is not always to most efficient, but can be very convenient.

Which NASA data in particular are you referring to? Some NASA data are also
available through opendap, making ftp transfer not necessary.

Subject: Can bufrscan read NCEP's prepbufr files?
Message-ID: <MON.12.OCT.2009.132007.0400.>

I am trying to have bufrscan read the prepbufr file created by NCEP.  When I sent the file to bufrscan, I get the output listed below.  I've tried this on Solaris using grads v1.9 and on Linux using version 2.0.  I've also tried blocking and unblocking the bufr file using cwordsh.  Is there any special processing I need to do to read these files with bufrscan?

Actually, I'm looking for ANY way to read and dump the prepbufr data on our 64-bit linux systems.  My attempts at building the bufr libraries and example programs from NCEP (and others) have not been successful.

Dear Pedro,
   Make sure you have Win32 GrADS installed and on your path. Open a regular
cmd.exe windows (DOS window) and type

C:\> grads

If it does not start then set your path accordingly. See the "Getting
Started with Win32 GrADS" document:

These are available with NASA's MERRA reanalysis. There several recipes

Ellav,
  One more thing. If you have the OpenGrADS Bundle distribution, just type
"merra" for a GUI for dealing with MERRA data over opendap. This is
described in a recipe as well.

As mentioned in that Recipe you can use LATS4d to convert the MERRA files to
GRIB-1. However, you may need to construct a LATS parameter table to make
sure the GRIB-1 dataset follows the NCEP conventions; see the lats4d
documentation refered to i the Recipe. (By default LATS4d creates a generic
GRIB-1 file which does not conform to NCEP or ECMWF conventions.) I have no
experience with WRF whatsoever. However, if you find a solution consider
writing a Recipe for it, I am sure other people would appreciate it.

Hi Arlindo,

Grad Users,

I am currently hoping to be a Grad user but unfortunately I am having
trouble figuring out what to download and then how to install it.  I am
using a PC with a Windows 95 system.  I have been on the GrADs website to dl
what it states I need in order to install the program but I do not know what
to do with the exe files and the dll files in order to install or start the
program.

I was wondering if anyone could give me step by step instructions on what to
download, how to install it, and how to open up the program.  Or perhaps a
helpful website to explain what I need to do.  I have NetCDF files that i
would like to look at using GraDS.
 Any help would be greatly appreciated.

Thank you,
Tierney

You should find detailed instructions about Windows installation here:

http://opengrads.org/wiki/index.php?title=Installing_GrADS_v2.0_on_Microsoft_Windows


As Hossein Lofti suggests, take a look at the tutorial. The authoritative
documentation is at this COLA website:
http://grads.iges.org/grads/gadoc/

<http://grads.iges.org/grads/gadoc/>The OpenGrADS Cookbooks have Recipes
illustrating basic GrADS usage.

  Have Fun!

Hello friends of grads!
I?m having a problem doing a wind direction 1D plot, for a single point,
with time variation only.
After setting the enviroment
set lat -42
set lon -32
set t (time) 1 13
I?m using this command:
d const(u,0);v;mag(u,v)

The problem:
I?m getting a plot with the proper format, but when verifying the direction
of the wind (at the point I?m setting the enviroment) in a bigger full plot
(set lat -70 -30, lon -60 0, set t 1),
I see that the direction is wrong!
the plot I get only point the vector to one side (upside) never downside...

do someone have an idea about what?s happening?

good day (or nigth!) to everybody,

Gabriel,
I don't understand why your display statement reads d *const(u,0)*;v;mag(u,v)
(hopefully you can see the bold italic text for "const(u,0)").  That doesn't
sound right.  To get 2-D wind direction, you should say "d u;v;mag(u,v)".
If you want one length to be zero, just subtract that variable from itself
(e.g., "d u-u;v;mag(u-u,v)").

Hope this helps.

Jeff

Hi Jeffrey,
I got this display line ( d *const(u,0)*;v;mag(u,v) ) at the GrAds
documentation...
But look an example of the product that I?m trying to do (in annex) (forget
the set vpage, etc)

thanks a lot!

Subject: g2ctl and wgrib2 problems
Message-ID: <WED.14.OCT.2009.100544.0700.>

Hi

?I am trying to get the g2ctl script to work under opensuse 11.1.
?I downloaded wgrib2 directly from cpc.ncep.noaa.gov and established that it does work is in my path etc.
?It runs fine on a nww3 file eg:

>wgrib2 -ctl_inv nww3.t18z.grib.grib2
1:0:WIND 1,0 0,2,1 none Wind Speed [m/s]
2:41554:WDIR 1,0 0,2,0 none Wind Direction (from which blowing) [deg]
etc .....

But if I try using g2ctl i get the following

wam/wave.20091013> /work/Gradsextra/g2ctl.pl nww3.t18z.grib.grib2

*** FATAL ERROR: unknown option -ctl_ens ***

Big problem:
? either nww3.t18z.grib.grib2 is missing or not a grib file
? or wgrib2 is not on your path or wgrib2 is too old
? or can not write to /tmp/g15864.tmp (full disk or permissions).

In Line 42 of g2ctl I have pointed to wgrib2 in the right place, and its in may path ie 
$wgrib2='/usr/local/Grads/bin/wgrib2';

Which is the latest available and seems to work

?Built Thu Mar 20 11:46:55 EDT 2008 for i686-pc-linux-gnu

Finally my disk is not fiull and I have write permission.

Anyone have some ideas where I am going wong and have some suggestions.

Many Thanks
? Jean Pierre

The -ctl_ens option was added to wgrib2 in order to support ensemble
control files.  v0.1.7.2 is too old.
So change line 42 of g2ctl to point to a newer version.

I found a script to calculate wind direction, but I don't know how to
calculate monthly wind direction for 30 years.
The number of times is 360 in my data.

Could you guys help me?

Hi Gabriel!

Try this way:

 d const(mag(u10m,v10m),0);u10m;v10m

My data is so big (~40MB) so I can't send it to you.
But my data is monthly grib data.
So for 30 years, each data is monthly.
Is it helpful?

Thank you for your reply.
My data is monthly for 30 years and it is grib data, so there are 360 data
sets.
Each data is monthly, then how can I calculate?
My data is so huge, so I can't send it to you.

Thanks,

Wansang

Dear All:

I created a netcdf file using "CDO".

"cdo -f nc chname,var11,sst -selhour,12 -selltype,1 -selcode,11 flx.ft06.200908"

I can read the netcdf file using ncdump. But when I try to sdfopen it
using grads  v2.0.a7.oga.2. The error "SDF file does not have any
non-coordinate variables" occurs.

More details of the error and the messange of ncdump are listed as
attatched. Your help are appreciated.

Subject: How to obtain an slice of Antarctic topography?
Message-ID: <WED.14.OCT.2009.220753.0300.>

Hi Grads Users,
Please, could you help me with this issue:
I am trying to draw a 2-D topography contour of complete Antarctica from one
coast to the other one at an arbitrary longitud.
I am using the file elev.1-deg.nc from
http://jisao.washington.edu/data/elevation/index.html#grads

So, when I define

set lat -90 -60

of course, I obtain an slice but only from the south pole to 60?S

when I set

set lat -50 50

the plot is only between 50?S and 50?N (not including south pole)
How can I get an slice, for instance, from 50?S to 50?N passing by the south
pole ?
Thanks in advance.
Hernan

yes, i can open it.
I think you need to open it with GradsC instead of Grads.

B.-J.,
  Here is your problem:

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

This is  not coards compliant. The time units should say something like

"days since 2009-08-01".

If you can't fix the file you can always create a DDF for it fixing the time
axis.

The -ctl_ens option was added to wgrib2 in order to support ensemble
control files.? v0.1.7.2 is too old.
So change line 42 of g2ctl to point to a newer version.

I have daily GCM output data with leap year and want to change it to
monthly mean. I try to do the average and modify it to seasonal, but I
didn't get the right monthly value. Do you have a code I can use to do
this? Thanks.

Hi, the gxout grid command is useless for my purpose because it just give to
me the value in the grid point coordinate. If I want the value for a point
that is, let's say, to the right or to the left  or between two grids points
How can I deploy this single value on a map?

You can set lat and set lon to any single values, then display the variable and it will print the value for that point in the terminal window (not print it on the map window).  However, I'm pretty sure that just gives you the value at the nearest grid point.  To interpolate to a specific location, I think you have to do your own calculation.  Then if you want it printed on the map, you have to do that as well (though there are lots of examples for that in the user group archive and maybe other places online.

Dear Grads User
    Is it possible to plot a any parameter like wind following
two-dimensional terrain in Grads?Actually i want to plot a figure like the

Set Lat,Lon to specific value ie.

'set lat 51'
'set lon 17'

then

'define t2 = tmp2m-273.15'
'q defval t2 1 1'
TMP=subwrd(result,3)
say TMP

Hi Piotr,

Try this script that I found from Grads20 a2.3, it may help you. 
============
*? Plots a string using current attributes
*? at "clicked on" position.? String can be provided
*? as an argument or will be prompted for 
*
function string (args)
? if (args='') 
??? say 'Enter string:'
??? pull args
? endif
? say 'Click where you want the string'
? 'query bpos'
? x = subwrd(result,3)
? y = subwrd(result,4)
? 'draw string 'x' 'y' 'args
=============================

Dear Arlindo:

Thank you. It works.

The default of netcdf file created by cdo is "absolute time axis". I
have to use the option "-r" to create the file in "relative time
axis". Then, the netcdf file can be read by grads. That is,

    -r             Convert from an absolute to a relative time axis
cdo -r -f nc chname,var11,sst -selhour,12 -selltype,1 -selcode,11
flx.ft06.200908

Message-ID: <FRI.16.OCT.2009.164245.0200.>

Hi,

I have problems with rotating ncdf files through opendap:  if I download a
file with rotated coordinates on my computer and use a suitable ctl file with
pdef etc. all work excellent, but if I try to use the same ctl file to read a
file which  is on an opendap server it doesn't work.

Is it possible to rotate fields using opendap connection?
Maybe I should prepare a different ctl file??

I would be very grateful for any suggestions!
Thank you!

Malgorzata

You need to give us more information. From the gradsusr guidelines (
http://grads.iges.org/grads/users.html):

*When reporting bugs or problems, please include the following information
in your post: *


   1. *The version of GrADS you are running (it is a good idea to include
      all the output from 'q config')*
      2. *The platform you are running GrADS on (e.g. SunOS, DEC Alpha,
      Windows95...)*
      3. *A brief description of the problem*
      4. *The simplest possible script that illustrates the problem*
      5. *The error messages from GrADS*
      6. *The output from running "ncdump -c" on your NetCDF file if you're
      having trouble getting GrADS to read the file.*

and from Mary Jo Nath:

How is your topography defined? Is it a separate variable? Or is it
indicated by the grid points with missing values in the field you are
plotting? If it's the missing values, then you can use "const" to
redefine the missing values, then use grfill to color them. I don't know
of a way to just outline them. Hope the example below helps. - MJ

Ex:

* missing value grid points now = 1.; all non-missing values = -var/var
= -1
define tmp=const(-var/var,1,-u)
* mask out the non-topography grid points
define topo=maskout(tmp,tmp)
* color the non-missing grid points in "topo" (the topography)
set gxout grfill
set ccolor 2
d topo

Hope this helps,

Hi

As far as I know a grads script that draws terrain in an arbitrary cross
section has not been compiled yet. So I've made one :) and am attaching it
for general use. hope it serves its purpose!

the prerequisite is that you have either a terrain variable (in this
script called topo) or something that can mimic the terrain in your grib
file.

cheers

One can see that t2 = air temperature  at two metres above ground  (K)

SDFWrite file name = airtemp.nc
SDFWrite will replace an existing file
SDFwrite file will have at least 4 dimensions
ga-> q sdfwrite
SDFwrite file name is: airtemp.nc
SDFwrite format is NetCDF
SDFwrite file will have at least 4 dimensions
ga-> define at = t2 -273.14
Notice:  Automatic Grid Interpolation Taking Place
Define memory allocation size = 112488 bytes
ga-> sdfwrite at
ga->


There is no error message but the file airtemp.nc is not located in any
directory on the computer.  This is Linux and the execution of  find
-name  "airtemp.nc"    indicates that  no file by that name is located
on the system.

We have done this several times using different output names but can
never find the named file.  To show at is defined, I have generated the
attached png file using the "d at "  command - so the variable at exists.

Any help with this will be greatly appreciated.

Hi Guilong,

You can fwrite the January data set out as a binary file, then write a ctl for it. Then you can plot the time series of January.

hi
i dont know if this is what you mean, but here is part of a script i add to
identify the date
'set t 'count
  'q time'
date=subwrd(result,3)
hour=substr(date,1,3)
day=substr(date,4,2)
month=substr(date,6,3)
year=substr(date,9,10)
date_str=hour' 'day'/'month'/'year
*....
*.....
*and then in the end
'draw xlab 'hour'.'day'.'month'.'year
is this what you need?

Hii teddy
    thanks for ur valuable reply. Actually my *wrfout** file has no topo
variable,  so when i created the ctl and dat file from *wrfout* file it
doesn't have any topo variable in the control file.I think it is in the *
met_em** file, so when i tried with the *met_em** file to create the *.ctl
and *.dat file it is giving some error like below. So just help me from
where i can get the topo variable.

*We are dealing with pressure levels here
 NetCDF error : bottom_top
   NetCDF: Invalid dimension ID or name *

*thanks and regards*

Dear Hao,
            Grads can open HDF files which agrees the COARDS convention. But
unfortunately the MODIS hdf files are not agreeing COARDS convention. So I
think we cannot open them through grads by writing a ctl file. You can
convert the data into ascii and then converting into binary we can write a
ctl file and then plot in grads. That is what my experience. Good
Luck.......

I can't allow misinformation to go out to the list uncorrected: GrADS
can read any HDF file containing gridded fields.
This particular HDF file contains swath data. It's gridded -- there
are 406 cells in the along-swath direction, and 270 cells in the
across-swath direction. GrADS will read this data, but only onto an
abstract x,y grid. The lat/lon values of each grid point are read in
as data variables. A full 'dtype hdfsds' descriptor file would include
the following lines:

xdef 270 linear 1 1
ydef 406 linear 1 1
tdef 1 linear ...
...
vars 4
Latitude=>scanlat 0  y,x  Geodetic Latitude
Longitude=>scanlon 0 y,x Geodetic Longitude
Scan_Start_Time=>scantime 0 y,x International Atomic Time at Start of
Scan replicated across the Swath
Surface_Temperature=>tsfc 0 y,x Surface_Temperature
endvars

You can add more variables, including some that have a Z axis,
depending on what you'd like to look at in the file. The rest of the
required descriptor file entries are discussed in the documentation
page http://iges.org/grads/gadoc/SDFdescriptorfile.html

I put this in my .ctl file as an example:

dtype hdfsds
vars 3

Longitude=>scanlon 0 y,x Geodetic Longitude
Surface_Pressure=>sfcpres 0 y,x Surface Pressure
endvars

But I got this warning:

Open Error:  Data file type invalid
   --> The invalid description file record is:
   --> dtype hdfsds

I am confused about the data type. Not HDF-SDS?

You are right. I found this:

o DTYPE netcdf and DTYPE hdfsds are DISABLED.

Do you know how to turn it on?

correctly.

hi
i dont know if this is what you mean, but here is part of a script i add to identify the date
'set t 'count
? 'q time'
date=subwrd(result,3)
hour=substr(date,1,3)
day=substr(date,4,2)

month=substr(date,6,3)
year=substr(date,9,10)
date_str=hour' 'day'/'month'/'year
*....
*.....
*and then in the end
'draw xlab 'hour'.'day'.'month'.'year 

is this what you need?

Dear colleagues,
I am trying to calculate the  correlation coefficients between a time series and global SST
using the tcorr function (http://www.iges.org/grads/gadoc/gradfunctcorr.html).But the function does not work.The tregr does not also work.

'open d:\analysis\EOF\eof_series1.ctl?"single time series:t=1,t=57; x=y=z= 1"
'open d:\analysis\DATA\winter_sst.ctl?"global: lon 0 360, lat -90 90; t=1,t=57,z=1"

'set lat -90 10'
'set z 1'
'set t 1'
'set gxout contour'

'd tcorr(series.1,winter.2,t=1,t=57)'

If I define an index  using the SST data (as in the documentation, above) it works and give reliable result.

Any ideas on what I've been doing wrong?

Thanks,
hyacinth

Hi Hyacinth
You first define the time series e.g.,
set t 1 100
define ts= <variable>
then use
d tcorr(ts,sst,t=1,t=100)

Hope this will work

Best

Hello,

Is it possible to place the color legend in a diferent place from the
acutal vpage position of the plot?

For example if I want to draw a 4X3 plot page (12 plots in total, 4 rows
and 3 columns) and the legend is the same for all of them. How can I
place the legend in the bottom of the hole page not in the botton of
each plot?

Thanks.

Esther.

Esther
sure you can
if you open the cbarn script that is in the same file as your grads probably
in a file called scripts
it explains as folows:
"run cbarn sf vert xmid ymid
*
*    sf   - scale the whole bar 1.0 = original 0.5 half the size, etc.
*    vert - 0 FORCES a horizontal bar = 1 a vertical bar
*    xmid - the x position on the virtual page the center the bar
*    ymid - the x position on the virtual page the center the bar
*
*    if vert,xmid,ymid are not specified, they are selected
*    as in the original algorithm"
good luck

Thanks!

But if I have used the "set vpage" command it will plot the legend
inside the virtual page defined, even if I don't specified any
parameter.

If I use after the plot "set vpage off" to return to the default state
where the real page equals the virtual one it says that does not have
any shading information.

I would like to have many plots but just one legend in the bottom of the
page...

Thanks again!

After your last plot, but before you change the vpage, put

'q shades'
_shades=result

Message-ID: <THU.22.OCT.2009.123624.0500.>

Hello,
I am using RUC model output for analyses and I have two variables that
confuse me.

Here is output from "q ctlinfo":

capesfc  0  157  ** surface Convective Avail. Pot. Energy [J/kg]
capeplg  0  157  ** Convective Avail. Pot. Energy [J/kg]

cinsfc  0  156  ** surface Convective inhibition [J/kg]
cinplg  0  156  ** Convective inhibition [J/kg]

For each of these pairs of thermodynamic variables, what is the "...plg"
one?  Is it some sort of mixed layer value?  Please help explain.

Jeff

I want to use loop to plot my graphics and I am wondering if there is a away to pre-define an array of character in grads that I can use for example in labeling the title of each graphic in a loop by index reference aka :

then use title(i).

Hi Ousmane:

I think you can do something like this:

title.1 = 'north'
title.2 = 'south'
title.3 = 'east'
i = 1
while ( i <= 3 )
.
.
.
'draw title 'title.i
i = i + 1
endwhile

Hi,
I am trying to install subject s/w for windows xp machine. I get two folders
downloaded bin and dll.


When I try to run an executable from bin I get error message that a dll file
was not found.

The file labeled INSTALL seems to just be an info file for unix install.


What do I have to do to fix this problem?

Thank you

Do you have cygwin installed on your system? First make sure the directory
where you have your DLLs is in your path. If it still complains about
missing DLLs you may need to install these using the standard cygwin setup
procedure.
More information about cygwin at http://cygwin.com.

You may find that the Win32 Superpack more straightforward to install. It
uses a traditional windows automatic installer that should get you going in
less than 5 minutes. All you need is included, no need to install cygwin
separately or get an X server. You will be able to run GrADS from the
[Start] menu, or from an icon on your desktop (just click on Ollie, the
friendly turtle.) You can download it from here:

http://sourceforge.net/projects/opengrads/files/grads2-windows/2.0.a7.oga.2/

Windows specific information available on this wiki:


http://opengrads.org/wiki/index.php?title=Installing_GrADS_v2.0_on_Microsoft_Windows

Although this build includes the opengrads extensions, you are free to
ignore them. This build should have all the same features found in the
regular v2.0.a7.1 build from COLA.

Hi,I think the color legend has to be inside the vpage. But for two columns
map display, you may plot 'cbarn' at both the vpage forcing the same mid
point so that it appears in the middle.

Hi!

I have fixed it in a not very elegant way but a way that works. I have
defined a new vpage and plot a white map (with nothing, no mapdraw, no
frame...) situated where I wanted to appear the color legend :-))

Thanks to all!

You could also use something like this:

titles = 'north south east'
'draw title ' subwrd(titles, i)

That's what I came up with before I saw Jim Potemra's answer, but it's
probably less efficient.

How are you able to generate one bar for all the plots with the vpage?

Esther,

You can make a new version of cbarn.gs that includes:
   'set vpage off'
after the shading info is stored, but before the plot size is determined.

I'm attaching a version I frequently use.  It includes extra optional
arguments to: reset the virtual page (what you want), modify the label
thickness, and print the values diagonally (useful for horizontal bars
with many values).

   I hope this helps.
      Diane

Dear Sir/Madam,
I have the model predicted data and Observational dataset.
The observations are available in ASCII format.
With this information, I request you to please suggest me
to plot both observed vs model predicted
datasets on one Skew-T gram or T-Phi gram.
Is there any script available directly to use both these datasets and plot
to compare the observed vs model derived profiles.
Is there any other software available directly to plot these variables on a T-Phi or
Skew-T diagram.

Thanking you for your help
Sincerely
Srinivas

Hi , can somebody help me with this?

I want to plot the grid points that my model has so that I can identify the
nearest grid point over land to the stations I'll be using for validation.

Your help are highly appreciated!

I have tried to place "set vpage off" many times correctly, but it never
worked!

Thanks again.

Hi, you can visualize your gridpoints by setting the following option
before displaying your model's variable "var":

'set gxout grfill'
'd var'

Message-ID: <MON.26.OCT.2009.215230.0100.>

Hi,
I have installed a win32 copy of grads GrADS1.9. Using GRADSDODS I can run a
GRADS script successfully if I place it in C:\GrADS\lib where other scripts
reside (eg cbarn.gs, etc).

I have tried moving this script to my own personal folder and setting the
environmental variable GASCRP to point to this folder.  There are two
classes of environmental variables System and User.

I believe you need admin privileges (which I don't have) to set up the
system variables. Anyway, gradsdods is not finding this script.

Any suggestions?

Thank you
Peter

Dear Grads users

It turns out my current logic is not correct. I am trying to find the
highest TMAX2m value for each point on the globe  from four 6-hour GFS
forecast hours and then plot this value, so that the single plot will
show the highest value for each of the 720x181 data points from the
0.5 GFS data covering a period of 24-hours. I know the answer is
probably simple, but I seem to making this harder than it should be.
Any help would be greatly appreciated.

Thanks.

I would think a simple "d max(tmp2m,t=(first),t=(last))" command should
work.  Granted, make sure you have your horizontal domain set to the entire
globe.

Which version exactly? Do a "q config".

How did you do this? Inside a BAT file? try

C:\> set GASCRP=C:\SOME\WHERE
C:\> gradsdods

You should be able to set this env variable from a BAT file or a VBScript.
If you download the Win32 Superpack, either v2.0 (recommended) or v1.10 you
can take a look at how the variables are set inside a VBScript (look at the
.vbs files in the top directory)

Hi,

 Is any possibility for installing GrADS in Windows Vista?
I share a 64bits laptop with this toy-Operative System and somtimes I need to work on this platform.

Dear Jeff,

Thanks for your response. Yes, your suggestion works just great,
however, there is a caveat. Without templating my GFS GRIB2 files your
suggestion was not possible. I merely used the new templating feature
for g2ctl (http://www.cpc.noaa.gov/products/wesley/g2ctl.html) and
then used your suggestion as in

'd max((((TMAX2m-273.16) *1.8) +32),t=9,t=15)'

It produced exactly what I was looking for. If templating is not used
all GFS GRIB files have only one t value and t does not vary and no
matter what I did, it would not work. Templating my GFS GRIB2 files
actually has allowed me to process my data a lot faster overall too.

Kevin,

I'm glad to hear it helped.  Indeed, templating helped me do my work much
faster as well.

Hi,

I want to plot tropospheric NO2 only over the Indian grid points (not Nepal, Pakistan
and BanglaDesh). Is there any such utility so that it will enable me to plot data only
for  India girds in GRADs. ( my grid size is 0.25 x 0.25 degrees).

Sachin,

You can use the maskout function to do this kind of thing, e.g.
'd maskout(no2,india_mask)'

but you first need to create a variable (india_mask in my example) that you can use to discriminate between points in India and the rest of your domain. If you don't have such a mask available, you'll have to create one, probably outside of GrADS (e.g. using FORTRAN).

See the GrADS website for details of maskout.

For example, your india_mask variable would have value 1 over India and some value <0 at all other locations. Maskout needs a field that is <0 at the points to be excluded.

the only chance you have to do it is using maskout function

you should prepare a mask with, as example, 1 over india only,
then: display maskout(no2,mask)

Problems



1)       I need to read with grads also the grib files with lat-long
"thinned" grids, I just know, by documentation, that my version (1.8SL11)
isn't able to manage this kind of grib files. I put in the attachment an
example of this kind of file (LFPW..)

2)       I have some files that are managed by grads without error (version
1.8SL11), but the display command says: "Entire Grid Undefined". I put in
the attachment an example of this kind of file (YMID..)



My questions



How can I view, on a picture, information contained in files like those in
the attachment?

Is there any version of GrADS that manage them?

Is there some work-around that I can follow to satisfy my need?

If no, do you know any other software that I can be used?

I'm assuming you are using the WRF, and if so you should have a variable
called LANDMASK in your history files...it takes on the values of 1 for land
and 0 for sea.  If you have that variable, you can use that as the mask.

Hello GrADS Users.

I run GrADS 1.9b4 on Sun Blade-1000, Solaris 5.9.

In my ctl file I wrote:

dset ^ECMWF0250_2009102700_000-240.grb
index ^ECMWF0250_2009102700_000-240.gmp
undef -999.9

But when I display an undefined variable, GrADS instead of saying
"Entire grid undefined", issues:
Cannot plot color bar: No shading information
Constant field.  Value = -999.9

It is a problem when I plot a variable map on an area where there are both defined
and undefined values or when I plot a time series over a gridpoint.

When I work on station data instead of GRIB grid data all works fine.

Any ideas?

Thank you in advance.

It sounds like you will need to do something like this:

1. Create a file listing all the grid points in or near India (e.g.,
within a simple latitude and longitude range that covers all of India
and some surrounding areas).

2. Import this list into a GIS program and intersect it with India's
land area.

3. Export a list of Indian grid points from the GIS program.

4. Import this list into GRADS.

Step 1 would be easy to do, e.g., in a text (.csv) file created in
Excel, if your grid is regularly spaced.

Step 2 and 3 are easy if you have a GIS program and difficult
otherwise. I could help you with that if you want.

I don't know how you would do Step 4. I can easily create a text file
listing all the relevant points, but I don't know how you would
reference that text file from GRADS to create a mask variable. Anyone
else have ideas about this?

Even when I set the time, for the time series file, the message occurs...Can

Hi,

Creating a masking file is not a simple procedure. Here I am sending you a
masking instruction I prepared (last year  for small training group in
Nepal). The masking file is for 0.1 resolution, so you need to edit a
little. The attached RAR file consists of a instruction file and two fortran
programs. In addition you will need ArcView GIS and India shape file
(boundary polygon) and fortran compiler. You should first edit the program
to suit your resolution. The rest should be clear from the instruction file.

Once the masking file has been created, simply replace the master file with
undefined values where grid point point values are zero in the masking file.

Hope it helps!

Wow, you used almost exactly the same approach I suggested (but with
more Fortran and less Excel)! Glad to know I was on to something.

I'm not fluent in Fortran, so I had trouble deciphering the
cr_mask_fl.f program that converts an ASCII list of points into an
ASCII masking file that GRADS can read. Would you be able to send a
sample of the final ASCII masking file that you produced and the
command you use to load it into GRADS? Or if there's an obvious place
to look in the instructions, that would be great too. So far I only
know how to get GRADS to read local or remote binary files. It would
be great to have a way to display data from ASCII/text files that I
create myself.

Best,

Matthias

Dear GrADS Users, 
? 
I am trying to calculate the correlation coefficients?by using the tcorr function, but after running the following script I just can to see a blank page. Please let me know, what the problem is! 
Any help would be really appreciated.

 Dear Abbas,
Before you display tcorr, you have to reset x, y, and t. I have make some changes to your code. I hope it helps or you can look at again. Also see the documentation page: http://www.iges.org/grads/gadoc/gradfunctcorr.html

Good luck,

Hi Matthias,

I am glad you liked it.

I am using FORTRAN as it is convenient to me. You can use any other language
which can handle binary files.

Basically, what GIS (ArcView) gives us is the IDs of the grid points which
are inside the country boundary. All my program does is assign 1s to those
points and 0s to rest of the points in a domain considered (mine happens to
be 86x46).

In binary file, replace all values by 'undefined' values (-999.0) where
masking file values are zero and save this as new file. Thats it.

Attached is the RAR file which comprises the following.
ASCII

masking file
unmasked-data file
masked-data file
(header file is also included to import it into ArcView)
control file - to display in grads

BINARY

unmasked data file
masked data file


If you have any query please let me know.

cheers!

-rupak

I am having another frustrating GrADS issue with GrADS2 on my mac.  I am trying
to make more station plots.  I have code to write out the station plot data.  I
have done this before with no problem, but get an error now.  I am attaching a
binary version of that file (fort.10) and a control file (fort.13).  When I run
that through stnmap, I get an error:

So, according to the first line, levs should be 1, flag should be zero, and time
should be zero.  But the above from stnmap has very different values.  Am I
missing something very fundamental from the documentation?  I'm stumped.

Thanks,

So, according to the first line, levs should be 1, flag should be zero, and time
should be zero.  But the above from stnmap has very different values.  Am I
missing something very fundamental from the documentation?  I'm stumped.

Thanks,
Sim

Sim,
Here's the comments from our local station map "expert"...
Caveat: he's still using grads1

1 check your options statement
2 check "endian ness"
3 see if you can stream the data (station map is written in C
and would be happier reading streaming data)

Good luck,
Austin Conaty

Subject: How to get Ascii output for each grid point of selected area
Message-ID: <SAT.31.OCT.2009.044349.0000.>


 Dear All,

I am having 1 dg by 1 dg data set
now I have selected the region say 5 N to 10 N and 65 E to 70 E over India
If I want data in ascii for each grid at one strock how to do it (Say for eg. (5,65), (6,65).........)
Is there any command for this

Thanks,

Subject: LATS available for GrADS v2.0
Message-ID: <SAT.31.OCT.2009.212451.0400.>

All,

    I just upload to sf.net version *2.0.a7.oga.3 *of the *OpenGrADS
Bundle*. This
OpenGrADS release adds support for *LATS*, a feature of GrADS v1.x which has
been dropped from COLA's GrADS v2.0 codebase. LATS is now implemented as an
OpenGrADS extension (see http://opengrads.org/doc/udxt/lats/) giving users
the ability to write NetCDF-3, NetCDF-4/HDF-5 (with and without
compression), HDF-4 and GRIB-1 from a single GrADS executable. With the LATS
extension, Lats4D <http://opengrads.org/wiki/index.php?title=Lats4D> has the
same capabilities in GrADS v2.0 as it once did in GrADS v1.x.

       This release also adds the extension *ORB* (see
http://opengrads.org/doc/udxt/orb/) which allows you to mask gridded
variables according to several satellite orbits.

      *NOTE:* Unless you are interested in these new extensions, there is no
reason to upgrade from v2.0.a7.oga.2.

For downloading,

*Linux, Mac OS X, sources:*


http://sourceforge.net/projects/opengrads/files/grads2-windows/2.0.a7.oga.3/

*Windows:*


http://sourceforge.net/projects/opengrads/files/grads2-windows/2.0.a7.oga.3/


  The NEWS file is reproduced below. Remember, these extensions should be
considered experimental. Use at your own risk.

  Enjoy and let me know of any problems.

      Arlindo



                    The OpenGrADS Bundle Distribution
                    ---------------------------------

                          http://opengrads.org

                        GrADS Version 2.0.a7.oga.3
                         Released 29 October 2009

This version is based on COLA's 2.0.a7 release which includes a new
interface for the native HDF-5 format, options for templating on Julian Day
and time axis, new funtion eloop, in addition to some bug fixes. See
the ChangeLog for details.

This OpenGrADS release adds support for LATS, a feature of GrADS v1.x
which has been dropped from COLA's GrADS v2.0 codebase. LATS is now
implemented as an OpenGrADS extention giving users the ability to
write NetCDF-3, NetCDF-4/HDF-5 (with and without compression), HDF-4
and GRIB-1 from a single GrADS executable. This release also adds the
extension ORB which allows you to mask gridded variables according to
several satellite orbits. See the included "Documentation.html" for an
in-depth description of these new extensions.

Several other important OpenGrADS additions are available with this version:

- grads is now built with NetCDF v4.0.1beta3 which includes support
  for NetCDF-4/HDF-5 (similar to gradsnc4 in v1.9.0-rc1) and has
  built in OPeNDAP support.

- gradsdap is no longer provided as its functionality is now included
  in the single executable *grads*.

- this is an OpenGrADS Bundle release, a relocatable, minimum
  configuration package that has all that you need to run GrADS. See
  INSTALL for additonal information.

- we have introduced option -C to enable colorized text

- preview release of the OpenGrADS Extensions; the same extensions
  available in GrADS v1.9.0-rc1 are now available with GrADS v2.0.

  Caveat: as COLA is yet to publish the official API for User Defined
          functions in GrADS v2.0 we have adopted here an API that
          is based on our work vith v1.9.0-rc1. This is a very low-level
          API that is *not* endorsed by COLA. As such, it is *not*
advisable
          that users adopt this API to write their own extensions.

- These extensions are still being fully tested. Please report any problems
  you encounter. Use them at your own risk.

- The following extensions are included: see below.
