WPS using ECMWF IFS ds113.1


Dear all,

I know I need to link and run ungrib.exe for suface and pl, respectively.
First, I downloaded ECMWF Operational 6-hourly atmospheric isobaric analysis files from
They looks like seperate files for each variable. I am not sure how to link the them before running ungrib.exe.

Thanks in advance for any suggestion.
You can put all the files to the same directory, then link them all by a single command:
./link_grib.csh /your directory of EC Data/*

WPS will then process all the files one bye one and extract those variables required by WRF.
