Change in soil variables from ECMWF Cycle 49r1

[gabrielcassol]

On November 12, ECMWF released version 49r1 of the operational IFS. Despite all the improvements, they modified the soil variables (temperature and moisture) which broke the ECMWF Vtable that had been released in the 4.6.0 version of the WPS.

I contacted the ECMWF team and they gave me this feedback. It is necessary to make a change within Ungrib, more specifically in the rd_grib2.F code so that it works with the new IFS soil variables.

With 49R1 cycle, encoding of soild parameters changed

• from stl1 , stl2, stl3 , and stl4 changed to sot.
• and from swvl1 , swvl2, swvl3, and swvl4 changed to vsw

ECMWF is currently one of the best global weather forecasting models. It is essential to have this data working in WRF so that regional weather centers can run WRF for their area of ​​interest. Could you take a look and try to find a solution to this problem?

Best Regards,
Gabriel
