Hi Randy-

Thanks for following up on this.

That's the way many people write netCDF - home brew with no convention
and then they wonder why other programs can't read them in.  The only
way then to look at the data is generically because there is no
standard metadata for a program to use (like where is this located?).
It's better to consider these issues from the start rather than wait
until you have a huge archive of randomly formatted files.  It's taken
the modelling community a long time to realize the importance of standards
and now most (except WRF) conform to the CF conventions.  This has made
huge gains in collaborative research and data sharing.

If you want to look at the files generically in the IDV, then you can
set the Data Type for the File chooser to be VisAD Form files (end of
the list.  (you'll have to gunzip them first).  Then pick the variable 
you want in the Field Selector and use the Omni Control.   You can use
the Mappings buttons to map whatever variable you want to the different
axes/display types.  (I used Azimuth->Cyl Az, Gate -> CylRad, Kdp->RGB)
But, the display will not be geolocated and you will not be able to
overlay any other types of data (except the similar files).
