Hi John-

We are using ADAS as part of the LEAD project and the version we
have puts out the data in netCDF files that the IDV can read.
I'm not sure which version of ADAS we are running compared to you
(it might be a research version), but that might be another option.

You should be able to put the GRIB files in the catalog and
point to them with the IDV.  The latest THREDDS Data Server (TDS)
supports this through OPeNDAP, but you should also be able to 
reference them as dataType GRID and serviceType netCDF in the
catalog.

Yes, I saw that message, but thought I'd put in my 2 cents in
case we could make this easier.
