20041217: LDM feed for Nexrad Data

Hi Eric,

As Carl Sinclair notes below, IRaDS will only feed 4 university sites
free-of-charge.  Those university sites, in turn, are the primary
conduit through which the Unidata university community gets the NEXRAD
Level II data for no charge.  Finally, the Unidata Program Center
is charged with controlling the topology for NEXRAD Level II data in
the university community.

Please provide us with the fully qualified hostname and associated IP
address of the machine on which you want to ingest Level II data.
After receiving this information, we will work with Plymouth State
University to get you allowed to request the data you need.

Please send any questions/comments about the Level II topology or
the IDD in general to Unidata User Support <address@hidden>.

Hello Tom (et al.) ,
    Just wanted to thank you for your help but we will not be needing this 
connection to Plymouth State right now.  Happy Holidays-  Eric Lyons
