The NOAA Profiler Network (NPN), consisting of 35 unmanned Doppler
Radar sites located in 18 central US states and Alaska, provides hourly vertical
wind profile data. The data produced by this network is distributed
to the National Weather Service (NWS), environmental research groups,
and Universities. The NPN has been operating continuously since 1992 and
celebrated its 15th Anniversary in 2007.
This web site provides the public with information
about the NPN and access to
real-time profiler data displays and status.
