[gradsusr] wgrib2.0.3

[Jennifer M Adams]

Hi, Thomas —
I believe the problem is that this file uses a jpeg compression algorithm that requires a patch to the jasper library in order to work properly. The COLA grads builds of version 2.1 are linked with the patched version of jasper library, and I am not getting any crashes when I look at the AROME data you directed me to.

If you are using opengrads on windows, and grads is crashing, and the wgrib2 exectuable doesn’t handle it, it is probably because those executables are linked with the wrong version of jasper.

p.s. The source code for the proper jasper library is inside Wesley’s latest wgrib2 tarballs. Back in December of 2013, I also posted it here: ftp://cola.gmu.edu/grads/Supplibs/2.1/src/jasper-1.900.1-10ubuntu1.debian.tar.gz

I can provide a direct link to download the data here:

When I try to plot any variable this is the error message displayed:

Could you provide a sample of the data that is causing GrADS to crash?

Thanks for your reply.

I have the latest version of OpenGrADS but not the latest version of wgrib2 which is not included in the latest release. Specifically wgrib2.0.3 is required in order to plot Arome 1.3km data and is only available as a tar/binary file ?

Hi

I havenw worked with the Arome model yet, but to my knowledge you don't have to compile a windows version of wgrib or wgrib2 for that matter. These binaries (executables) are provided when you install "Opengrads"
https://sourceforge.net/projects/opengrads/files/

What you then need to do is install Perl for windows, so you are able to run the perl scripts grib2ctl & g2ctl (for respectively grib1 & grib2 files)
I use "Activestate" for this. http://www.activestate.com/activeperl/downloads

The windows installation of grads will place wgrib & such in the windows "environment vars", so you don't need to worry about those.


Hope this helps.

Best regards

Hi,

In order to plot high resolution MeteoFrance Arome data (1.3km grid), I need to install the latest version of wgrib2 (2.0.3 I think) otherwise GrADS crashes when I try to plot any variables.

If anybody can compile or offer a windows executable of wgrib2.0.3 I would be very grateful as I have no idea how to compile on my system

Thanks in advance.
