[IDV #XAV-623062]: Sounding display problem

Hi Dan-

I sent a note to the maintainer of that server to see if they can add in the
units.   Without that, there's not much we can do on the IDV end.  I'll let
you know if I hear anything.

The only other option I have for you is to use the 1x1 degree grids from the
NOMADS system at NCDC.  Their server does include the units.
