Bill,

The CWOP weather data (nearly 5000 ham and non-ham weather stations) go 
through MADIS and then to all NWS WFOs where the data can appear on the 
AWIPS workstations.  Note this is on the operational WFO work stations, 
not on some PC running over in the corner.  The data also go to the 
National Center for Environmental Prediction (NCEP) where they are used 
in operational numerical weather prediction.  In fact, the CWOP data 
routinely go to over 450 user agencies (note agencies, not individuals) 
for use in research, operations and other activities.
