I've been attempting to decode the GFS ensemble data from the "new"CONDUIT NCEP ftp directory, as described inhttp://www.unidata.ucar.edu/data/conduit/ldm_idd/ensemble_files.html#GRIB2.However, dcgrib2 is not able to determine the GEMPAK parameter name, andno GEMPAK grid is created. I've attached the output from the dcgrib2 log.
Command line used: dcgrib2 -v 4 -d dcgrib.log YYMMHHDD_gefs_@@@.gem <gec00.t12z.pgrb2af48

Any ideas?

Thanks,

Kevin
