[Support #HKV-830940]: question about LDM IP address

Hi all, 

..and apologies for the delay, new children really take it out of you :)

The RAWS data IS in the MADIS feed from GSD.

Please contact:

Mike Barth <address@hidden>

and see:

http://madis.noaa.gov/data_application.html

..for more information and to set up your feed.

You will still be getting the satellite data from us, so if you know 
what wavelength and resolution, we can get that started. Or you can get 
the whole feed and see what suits your needs best.

I am working more or less my regular schedule now, so hopefully we can 
get things rolling.

Cheers,

Jeff
