Hello gembuds, Since the recent NAM upgrade, my call to DCGRIB2 to decode some of the fields into GEMPAK format files has been failing. In particular, here’s an example command and the error message: dcgrib2 -m 10000 -v 1 -d logs/dcgrib2_namnest.log -e GEMTBL=$GEMTBL -e MDMETH=MDGDEC YYYYMMDDHHfFFF_nam4km.gem < nam.t00z.conusnest.hiresf60.tm00.grib2 Opening WMO Originating Center Table wmocenter.tbl... Opening WMO GRIB2 Parameter Table g2varswmo2.tbl... Opening WMO GRIB2 Vertical Coordinate Table g2vcrdwmo2.tbl... Abort trap: 6 So, not a very instructive error message, unfortunately. The GRIB2 files can be found at (for example): http://nomads.ncep.noaa.gov/pub/data/nccf/com/nam/prod/nam.20170322/nam.t00z.conusnest.hiresf60.tm00.grib2 <http://nomads.ncep.noaa.gov/pub/data/nccf/com/nam/prod/nam.20170322/nam.t00z.conusnest.hiresf60.tm00.grib2> (although I’m only pulling a subset of fields…but I also tested a full file and got the same result) I’m using GEMPAK 7.3.1 on a Mac OS X. This command always worked prior to the NAM upgrade, and NAGRIB2 works just fine on these new files, so I suspect there’s just something in the decoder tables, etc., for DCGRIB2 that need to be updated. Any ideas/solutions would be welcome — thanks! Russ -- Russ S.
