Radar Product Central Collection/Distribution Service (RPCCDS)
Next Generation Weather Radar (NEXRAD) makes conventional reflectivity
observations and also uses the "Doppler effect" to measure motion of
clear air and atmospheric phenomena within storms. The maximum range of NEXRAD is
230 kilometers (125 nautical miles). Although NEXRAD is land-based, there is some radar coverage offshore. The greatest offshore coverage is along the Atlantic and Gulf coasts.
External NEXRAD Radar data users can receive products through the Radar Product
Central Collection/Distribution Service (RPCCDS) by a variety of means.
Visit the RPCCDS Webpage for further details.
NEXRAD Doppler Radar images are available on the Internet from the NWS Homepage and local NWS Forecast Offices.
NEXRAD Doppler Radar images may also be found on
local cable channels and the Internet webpages of local media including TV stations, radio stations and newspapers as well as others. Use one of Internet search engines to search on topics such as "NEXRAD radar".
An archive of NEXRAD data is available at the
National Center for Environmental Information.
