[gradsusr] ARWpost to Grib

[Andrew Revering]

I may not understand correctly, but I know that the WRF EMS package has the
ability to output the data in GRIB1 or GRIB2 format directly after running.
It's just a matter of turning on that option in the configuration files.

Hallo people,

 

I'm working currently with WRF and doing the postprocessing with ARWpost.
I'd like to convert the output from ARWpost into Grib format. I've tried to
use GrADS with 'lats4d' but I have found something wrog. In order to check
the transformation of the files I compare surface varibles, like T2,
available both before the transformation (WRF in NetCDF format) and after
the transformation (the GRIB file). I'm quite surprised because the
differences change considerably: for the same grid many times are the
differences of the order of 0.01°C but some times are they close to 1.0°. I
don't know if the problem boils down to some interpolations problem.

 

My question ist: has anybody experienced the same problem? is a such
difference, in your opinion, acceptable?

 

I'd appreciate your help.

 

Ferdinand
