Solution proposed here: https://forum.mmm.ucar.edu/threads/change-in-soil-variables-from-ecmwf-cycle-49r1.19864/page-4 works correctly with files provided by figurski on 8.4.2025.
SD-110337 - Getting issue details... STATUS
Model configuration is here:
/perm/usbk/wrf/run_IFS_4km_opendata/
The two files not yet in WRF official release required to process the Open Data are in the directory above:
rd_grib2.F this is modified file and would replace file with the same name in:
/perm/usbk/wrf_module/4.6.1_grib2/WPS-master/ungrib/src/
- Vtable.ECMWF_GRIB2.txt is updated table with ECMWF' GRIB2 definitions
Since one of the ungrib programs needs to be modified, I have a separate installation of WRF for ECMWF' GRIB2 in:
/perm/usbk/wrf_module/4.6.1_grib2/
This still hasn't been added to official WRF release. Relevant external links:
