Hi Russ, Did you verify that you have grids up through F48 in there now? I just looked at mine, and my GEMPAK file reaches the maximum # of grids (29999) prior to F48. --Kevin _____________________________________________ Kevin Tyle, Manager of Departmental Computing Dept. of Atmospheric & Environmental Sciences University at Albany Earth Science 235, 1400 Washington Avenue Albany, NY 12222 Email: ktyle@xxxxxxxxxx<mailto:ktyle@xxxxxxxxxx> Phone: 518-442-4578 _____________________________________________ From: gembud-bounces@xxxxxxxxxxxxxxxx [mailto:gembud-bounces@xxxxxxxxxxxxxxxx] On Behalf Of Russ Schumacher Sent: Wednesday, March 22, 2017 2:09 PM To: Mullenax, Robert R. (WFF-820.0)[ORBITAL SCIENCES CORPORATION] <robert.r.mullenax@xxxxxxxx> Cc: gembud@xxxxxxxxxxxxxxxx Subject: Re: [gembud] DCGRIB2 failing on new NAM CONUS-nest files And one other GEMPAK quirk that has come up with the new NAM files (for all of the resolutions, not just the nest): plotting accumulated precipitation for periods longer than ~36 hours no longer appears to work. (example below from the 40-km grid) I assume that this has to do with the change from hourly files only in the first 36 hrs, to hourly files throughout the forecast. But I’m not sure how to figure out a fix for that. Any insights from the GEMPAK gurus would be welcome!

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 (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.
