Hello everyone, I tried to start WPS with ECMWF data but I got this error:


(base) wrf@DESKTOP-68KO52O:~/WRF/WPS$ ./ungrib.exe
*** Starting program ungrib.exe ***
Start_date = 2026-05-01_12:00:00 , End_date = 2026-05-02_12:00:00
output format is WPS
Path to intermediate files is ./
getdrstemplate: DRS Template 42 not defined.
getdrstemplate: DRS Template 42 not defined.
ERROR extracting field gf_getfld = 12
getdrstemplate: DRS Template 42 not defined.
ERROR extracting field gf_getfld = 12

It’s also generating empty FILE outputs. I’m not sure what to do—can anyone help me?

there should be some threads already talking about the ecmwf data issue with ifs, i would recommend searching those to see if there is a viable solution.

William,
Unfortunately, I only noticed the question addressed to me today. I'll get around to it in May and need to double-check if it works for me. When I was working on solving this problem, I ran tests and everything worked. I'll double-check.
