Re: Problems decoding GRIB2 GFS Ensemble grids

Hi Steve,

Thanks for the updated files.  I can now get it to work using the
GEMPAK5.9.3 version of dcgrib2 using the corrected tables.  However, even
with the updated tables, versions 5.9.1 and 5.7.4 of dcgrib2 still do not
decode.  Perhaps I shall just recompile dcgrib2 for use in these two
distributions (which are still in operational use here) unless you have
another idea.

The GEMPAK GRIB2 parameter tables use 4 numbers to define the parameter
The 4th column is the parameter template, which allows different names
to be assigned depending on the type ofaccumulation, average, ensemble
etc. used.
Log messages from dcgrib2 under "decode_grib2 -34" about unknown
mean that the decoder tables need to be updated (in particular, entries
for ensemble PDTs 1 and 11 in column 4).

Updated g2varswmo2.tbl and g2varsncep1.tbl tables which include the
ensemble entries can be downloaded from:
