Hi Tom,

If you are still having trouble with this, could you try it in the latest 
ToolsUI 4.2 (beta 2)? It is available on the netCDF-Java web page

http://www.unidata.ucar.edu/software/netcdf-java/

Make sure the "Add Coordinates" option (the flower pot icon) is turned off. 
That may be the setting that is causing trouble. (Yes, there is a ToolsUI 
config directory. It is in $HOME/.unidata.) Though I'm not sure "Add 
Coordinates" is the problem as it works for me in the Viewer tab whether the 
"Add Coordinates" option is on or not.

On the other hand, when I try to open it in the "CoordSys" or "Grids" tabs, the 
NsslRadarMosaicConvention still tries to handle it and still throws a 
NullPointerException.

OK. I just added a check to the NRMC.isMine() method for two dimensions, "Lat" 
and "Lon", that it uses elsewhere in the code. Now if they don't exist, like in 
your example file, the NRMC won't claim the dataset as one it knows how to 
handle. Though I'm not sure the result, no action or message, is actually much 
better than getting a NPException.
