Greetings Jian,
netCDF-Java and the TDS should handle the case of GRIB files with more
than one GDS, for example the NWS Firenest grids:
http://thredds.ucar.edu/thredds/catalog/grib/NCEP/NAM/Firewxnest/catalog.html
In this catalog, there are two "types" of Full and Best collections:
LambertConformal_564X494 (Center 31.03N 83.01W)
LambertConformal_370X509 (Center 32.98N 111.1W)
Each one references a different collection of GDSs. While the name
sure looks ugly, the TDS can be configured to rename them with
something more easy to understand. See "Example 3 (Multiple Groups)"
here:
http://www.unidata.ucar.edu/software/thredds/current/tds/reference/collections/GribCollections.html
We do not rename these different GDSs, as the nested domain changes
often, but it is nice to do for archived datasets.
Cheers,
Sean
