Julien,

John mentioned in one of his responses that this functionality was not
currently available, but i thought of an intermediate solution. The
solution would require some manual editing of the index file that was
created for your data file. In the second section of the index, the 12th
field from the left is the Gdskey that designates which GDS that the
parmeter belongs too.  See file, IndexFormat.txt in the base of the
distribution or in the java-docs. The process would require you to delete
all the Gdskey parameters except the one that you want to convert to a
NetCDF file. Also in section 3 of the index you delete all the GDS except
the one that you want.  That's it.

% java -Xmx256m ucar/grib/grib1/Grib1Indexer <input file> <input file>.gbx
or
% java -Xmx256m ucar/grib/grib2/Grib2Indexer <input file> <input file>.gbx

edit <input file>.gbx

# Grib2Netcdf outputs works on either Grib 1 or 2 inputs
% java -Xmx256m  ucar/nc2/iosp/grib/Grib2Netcdf  <input file>  <output.nc>
