NEXRAD
Next Generation Weather Radar

The Next Generation Weather Radar (NEXRAD) is a network of high-resolution, S-band radars operated by the National Weather Service (NWS), the Federal Aviation Administration (FAA), and the United States Air Force. NEXRAD measures the magnitude of the returned energy to provide reflectivity, velocity, and spectrum width observations, which can be processed to create mosaic maps of precipitation. NEXRAD radars typically operate with a 0.9 degree beamwidth, 0.25-1 km spatial resolution, and 230-460 km maximum range. There are currently over 160 NEXRAD radars operating in the United States and select overseas locations.
