[IDV #GYA-404192]: aggregatin nc files

Hi HP-
 
> No rain today (and yesterday) ... waiting now for Tuesday next week.

We had a nice downpour last night which has really cleared the air.

You could add:

<variable name="latitude">
<attribute name="units" value="degrees"/>
</variable>

<variable name="longitude">
<attribute name="units" value="degrees"/>
</variable>

Okay, I know John has been working on the BUFR stuff on the netCDF side.
We can't do anything on the IDV side until that is done.

I'll look into the HDF files. However, I wouldn't hold out hope for the
soundings by August 30.  That still requires some work on the netCDF side
before we can do the IDV access.
