Todd,

I'm not familar with the eta ST forecast grib file so I couldn't give you
particular  details about it.  But, I believe the it's possible to create
a cdl file for the model with a little trial and error work using gribtonc
in verbose mode. First I would start with the eta.cdl file as a template,
then add the new parameters to the file.  The verbose output actually
specifies the parameter names so you will be able to add these parameters
until the output doesn't contain any error messages. This can be done from
the command line, ie

% gribtonc -vl - etasl.cdl output.nc < <raw grib file>

Look at the man page for further details.  After one creates the file, it
can be viewed via

% ncdump output.nc

The raw grib file can be view via

% gribdump <raw grib file>

After this process is complete one can remove unused parameters.
