20040514: GEMPAK to GRIB conversion program available?



Jon,

GDGRIB is used to create a grib formated product from a GEMPAK grid.
See phelp gdgrib for usage.

Since several additional parameters are necessary for the
grib product, eg pds block values, those parameters are
input on a per grid basis. That is, you have to run the program
for each grid you want to create a grib product for.

The HPC uses this program to create grib products operationally.
