I am converting a model nature runs in grib1 format into gempak format.
Since the nature runs can have 4 digit
forecast hours nagrib returns "Error setting date/time"
for instance model initialization time was 2005 05 01 1200 UTC. I have
2006/04/01 1200UTC grib file. So this is about 7000-8000 forecast hour.
I tested some model outputs with smaller forecast hours, and it
any ideas how to tell nagrib to increase the digits representing
or any other way to get around the problem
