John,

I added the ability to read the 2D and 3D NetCDF grids as a radar type of image,
where the NetCDF file is specified as the RADFIL, or under the $RAD tree for 
NMAP2.
GEMPAK already had the capability of reading AWIPS NetCDF satellite images,
so this is just an extension of that.

The 3D grids get pretty sparse above the lowest levels when viewed ad 2d plan 
view
(the level can be specified in the NMAP2 interface just as the level 2 radar 
tilts).

Given the size of the NetCDF files we are getting from NSSL, and the amount of 
CPU needed
to un-gzip them, I'm looking at another solution such as reformatting the grids 
as GRIB2
products (as it takes some 13 GB of tiles to do a 3hr loop at the moment.
