Hi,
NODC recently announced their new OPeNDAP server
(http://data.nodc.noaa.gov/opendap/). There's a bunch of wonderful
data available there, but of course the first one I tried didn't work
out very well using Java netCDF tools.
To start with it is an HDF file (or so I assume from the file name
extension). Ferret able to make sense of the geo-referencing in the
file and make a plot. However, I think because the "coordinate
variables" don't follow the convention of having the same name as
their dimension (I assume because of the trickery involved in reading
the HDF file via the netCDF API), the Jave netCDF tools can't make
sense of the file (from the point of view of geo-referencing based on
conventions). I tried my tools and the latest toolsUI.
Is there something that can be done with ncML to augment the metadata
or create new variables that would allow the Java netCDF library to
make see the variables as geo-referenced grids?

CDM release 4.0.48.5 has a workaround for this. Let me know if you see
further problems. thanks...
