CONDUIT users and Gembuds, As you know, the CONDUIT data feed recently dropped the NAM 104 grids in GRIB1 format. We are receiving the 90-km NAM grids in GRIB2 format under the following pqact entry: CONDUIT /nam\.t(..)z\.grbgrd.*grib2 Most everything looks fine; however, when I convert these files to GEMPAK using dcgrib2 from 5.9.4, 5.10.3, or 5.10.4, the PMSL field isall fouled up. The following URL shows what I get for a 'CINT=0' setting: http://www.atmos.washington.edu/~ovens/2007110600_badpmsl.gif
Here's how I decoded the file: $GEMEXE/dcgrib2 -d - 2007110600_nam104.gem < \ /home/disk/data/conduit/nam.20071106/nam.t00z.grbgrd00.tm00.grib2 I suspect this is a problem with the GRIB2 file (my first guess) or the way GEMPAK is decoding the sea-level pressure field. Does anyone have a fix for this yet? Thanks, David -- David Ovens e-mail: ovens@xxxxxxxxxxxxxxxxxxxx Research Meteorologist phone: (206) 685-8108 Dept of Atm.
