wrfout in grib2 format

[cjones]

hello,

I am using WRF 4.0.1 and everything runs fine. However, I now want to save the WRF output in grib2 instead of netcdf format.

I specify io_form_history = 10 in namelist.input
but i get an error message in the rsl.error.xxxx files like this:

the model continues to run but the it doesn't write the output.

using the option for grib1 seems to work.

any ideas are greatly appreciated.

Cheers,

Hi,
Upon doing some research, I've found previous emails in the past couple of years stating that we are aware that the GRIB2 option does not work, but haven't had the resources to correct the problem. The person who would know for sure is out of the office this week, but I can try to get back to you on that.

If the above is no longer accurate, and since you are able to get GRIB1 output to work, but not GRIB2, it could also be a library problem. You would need the jasper, zlib, and libpng libraries installed, with JASPERLIB and JASPERINC set in your environment script PRIOR to building WRF. If you think this may be the problem, correct that, then issue a 'clean -a', reconfigure, and recompile. If the problem persists, it is very likely that the option just isn't working.
