Hi Fred,

re
>The GOES data is coming from the Unidata East and West ADDE serves at SSEC.

I figured as much.  By the way, we have installed a GOES-West SDI here
at UCAR (at the Mesa) and will be working on a GOES-East one (timetable
is unspecified).  We will then be able to act as a backup/secondary
source for full GOES imagery.

These are the SATEPS servers that I referred to.  We have access to
them as well.

I have been working with EUMETSAT to make METEOSAT data available by
ADDE directly.  This is a slow, uphill battle given their data
policies.

I figured that this was the case as well.

I guess that this would be the safest approach since it would conform
to EUMETSAT's data policy.  I can tell you, however, that the SSEC
global Mollweide imagery being delivered in the IDD UNIWISC feed
contain current MSG data.  EUMETSAT is apparently "unofficially" aware
of this and has not negatively commented.  I am guessing, however, that
if they were "officially" made aware of this, the practice might have
to stop.  The "realtime" restrictions on METEOSAT data (i.e., the data
must be 24 hours old before it can be freely redistributed) is a real
shame _especially_ given that full MSG data is being broadcast
throughout Europe and Africa in realtime.  Anyone in Europe and Africa
can purchase a decrypter key from EUMETSAT and get all of the data in
realtime.  They cannot, however, redistribute it.

OK.  Calling them GEMPAK satellite images is, therefore, a bit offbase.
They would be usable in any application that supports McIDAS AREA files
(e.g., McIDAS, IDV, Matlab, IDL, AND GEMPAK).

>I will talk to Chris Herbster about becoming a regional data server site.  I

Excellent!  Again, I have talked to Chris about more than once while he
was in Boulder attending Unidata User Committee meetings.  He has been
open to ERAU being a data source site for NOAAPORT data and has
expressed interest in being a community data server site.  This service
would be a wonderful contribution to the Unidata community!

Cheers,

Tom
