Issue to ungrib ECMWF operational data (not ERA5 data)

[mantovani]

Hi there,

I am trying to using ECMWF forecast (not ERA5) as IC to run MPAS model. To achieve it, I'm trying to execute ungrib.exe using both pressure level and surface level files from ECMWF data. I downloaded this data (not the public free data) and use the Vtable.ECMWF. However, the ungrib.exe returns the error message:

[wrf@hpcadm TRY]$ ./ungrib.exe
*** Starting program ungrib.exe ***
Start_date = 2024-01-07_00:00:00 , End_date = 2024-01-07_00:00:00
output format is WPS
Path to intermediate files is ./
ERROR: Grib2 file or date problem, stopping in edition_num.

If I use the g1print.exe from ungrib directory it returns for both SFC and PL files:

[wrf@hpcadm ungrib]$ ./g1print.exe /staging/wrf/ECMWF_IC/2024010700/PL_COMPLETO/ECMWF_PL_20240107_00_global.grib

Someone can help me?

Hi,
Can you issue the following from the WPS directory?
ls -ls GRIBFILE* >& gribfile.txt
and then attach that gribfile.txt file? Thanks!
