Hi Jian,
Our situation is a bit complicated.
We are trying to access the GRIB2 file by TDS / ToolsUI without any
processes on the file...
So grib_copy may be not a solution for us.
Thanks a lot.
Cheers,
Keith

Greetings Sean,
yes, you remind me that it works for one of our model with different
GDS too here but not for C1D of ECMWF.
Sorry for the misleading here lol...
But it did work when I split the C1D files as I said before.
Let's see if Keith have try out my method...
Thanks a lot.
Cheers,

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
<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
<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
