Patrick and Neil, Scott and I worked out the missing vertical coordinate and parms for the grib1 NAVGEM. see http://www.unidata.ucar.edu/downloads/gempak/latest/navgem.tar for the latest tables. I tested it with every parm available from http://www.usgodae.org/pub/outgoing/fnmoc/models/nogaps/ if you two can confirm dcgrib2 working with these tables I will update the source with these changes. -Michael Ticket Details =================== Ticket ID: KCH-144722 Department: Support GEMPAK Priority: Normal Status: Open
