Hi Otis,

re:
> Hi from Asheville!

I hear Asheville is a great place.  My sister lives near there, and she loves
the area (especially since she is now away from the hurricanes that used to
pummel her and her husband when she lived out on the coast of NC).

OK, thanks for the link.

No worries for us.  I just added an ALLOW for all non-restricted IDD feeds
for all machines in the cicsnc.org domain on idd.cise-nsf.gov.  Let's start
with that and tackle idd.unidata.ucar.edu later (it is a cluster, so the
configuration is more arduous).

As a reiteration of your request, you will be REQUESTing the following
feeds from idd.cise-nsf.gov:

IDS|DDPLUS - global observational data
UNIWISC    - aka MCIDAS; GOES-East/West image sectors

Of course, there is a LOT more data to be had... a snapshot taken a minute
ago shows the various feeds and their respective data volumes:

The volume will be going up measurably as dual polarization products are
added to the NEXRAD2 (NEXRAD Level II volume scan data) and NEXRAD3 (NEXRAD
Level III products) feeds.

Very good.  I think that David and Kim should allow your LIGHTNING feed requests
as soon as they understand why your machine is in the .org domain.

Cheers,

Tom
