The WSR-88D Doppler radar (NEXRAD) represents the backbone of the severe weather warning system in the United States for both the National Weather Service (NWS) and Department of Defense (DoD). There are a total of 159 NEXRAD sites, including Alaska, Guam, Hawaii, and Puerto Rico. There are also many Doppler radars operated by major market television stations. A more specialized weather radar for the detection of microbursts in the vicinity of some large airports is the Terminal Doppler Weather Radar (TDWR), operated by the Federal Aviation Administration (FAA). Installation of dual polarization capabilities, which allows better determination of precipitation phase and particle sizes, was completed in 2013. A new technology that may eventually become operational is Phased Array Radar, an adaptation of military technology that will allow faster scan rates. Listed below are some resources for information on weather radars. The list of commercial vendors does not necessarily represent official endorsement by the NWA.
