Hi Gerald:

You should be able to use it. The stability and code quality is moderately
good. However, until we implement the NetCDF-4 reader, we are not sure if the
API might need some (probably minor) changes. We anticipate a stable NetCDF-4
format by fall of 2006.

the size of the .5 degree grids are large, so the nc file will probably be
over 2 gigs.

there is a command line program call Grib2Netcdf,
% java -Xmx512m -classpath $CP ucar.nc2.iosp.grib.Grib2Netcdf $INPUT $NC

where $CP is CLASSPATH and of course $INPUT input grib and $NC is output
file.
