Doug,These settings work with real-time data and might be adaptable to your scenario:
GDATTIM = f12 GLEVEL = 950 GVCORD = pres GFUNC = thte(pres,tmpc,dwpc+2) GDFILE = $MODEL/nam/22022512_nam212.gem+$MODEL/gfs/22022512_gfs211.gem Sincerely, Steve On 2/25/22 2:19 PM, Douglas Miller wrote:
Dear GEMPAK users,I'm interested in creating maps of equivalent potential temperature (THTE) using ERA5 files (from the NCAR archive) in which fields on a given day are archived in separate grib files. I'm running into a roadblock after creating separate GEMPAK format files of each field and then can't figure out how to get GEMPAK to recognize TMPK from one file and RELH from another to calculate THTE on the fly. Is the only solution to merge separate ERA5 grib files/fields into a single "mega" GEMPAK file?Thank you, in advance, for any suggestions you might have on avoiding the "mega" file!Regards, Doug Douglas K.
