That's all the IDV knows is that a grid could not be made from the structure of 
the dataset.  The underlying netcdf-java library doesn't tell us why.

That would be great.

I wonder if it would pass the CF compliance checker?  I think the best thing is 
to let the ferret team know and get them to make it truly CF-1.0 compliant.  
Thanks for following up on that.
