[IDV #WRE-134204]: Error reading received from .netCDF file

Hi Ryan-

I don't know.  The problem on the IDV side is that the missing lat/lon values
make it impossible to efficiently resample the grid for displaying in
alternate projections, doing calculations, etc.  With a dimensionless
vertical coordinate, we need to do a look between the sigma coordinates
and the corresponding lat/lon/alt locations for the display. Since you can't 
reproject data in VAPOR, perhaps it will work.  I'm not sure if they
handle the sigma coordinates.

Good luck on the research and perhaps I'll see you at AMS next year.
