Robb: Will the next Decoders release support GRIB2?
Brian,
The current status: a grib2 (Dump program) has been written in Java. I
haven't been able to work on it for 6 months, the plan is to add
the netcdf API on top of the dump program. Hopefully I will be able to
restart work on it soon. The NDFD grib2 files will be easy to create but
some of the stitched grid models require more work. For sure a grib2
decoder will be available when the NWS starts regular distribution in
grib2.
Robb...
Tom: Does Unidata still offer the gribdec.tar.Z package for converting GRIB
to McIDAS GRID? I don't see it in the downloads section
http://my.unidata.ucar.edu/modules.php?name=Downloads&d_op= of the
my.unidata website? If the gribdec.tar.Z package IS still available, are
there plans for it to support GRIB2?
Thanks,
