Hi Aaron, Is the grib2 file you attached intended as a single-record example or is it the full file you are producing? I ask because the only record shown by wgrib2 is: > wgrib2 -v2 test.grib2 1:0:01Z14oct2009:BREF Base Reflectivity [dB]:lvl1=(255,missing) lvl2=(255,missing):no_level:: and after adding TAMU to wmocenter.tbl (center ID 199) I see "No GRIB record was found" error messages both with dcgrib2 and nagrib2.
