Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
NEXRAD or Nexrad (Next-Generation Radar) is a network of 159 high-resolution S-band Doppler weather radars operated by the National Weather Service (NWS), an agency of the National Oceanic and Atmospheric Administration (NOAA) within the United States Department of Commerce, the Federal Aviation Administration (FAA) within the Department of Transportation, and the U.S. Air Force within the ...
Weather Underground uses observations from over 250,000 personal weather stations worldwide. [21] The Weather Underground's WunderMap overlays weather data from personal weather stations and official National Weather Service stations on a Mapbox Map base and provides many interactive and dynamically updated weather and environmental layers.

Map of regions covered by the 122 Weather Forecast Offices. The National Weather Service operates 122 weather forecast offices. [1] [2] Each weather forecast office (WFO or NWSFO) has a geographic area of responsibility, also known as a county warning area, for issuing local public, marine, aviation, fire, and hydrology forecasts.
The frequency selection of weather radar is a performance compromise between precipitation reflectivity and attenuation due to atmospheric water vapor. Some weather radars uses doppler shift to measure wind speeds and dual-polarization for identification of types of precipitations. Weather radar; Wind profilers; Millimetre cloud radar; CODAR
The Advanced Weather Interactive Processing System (AWIPS) is a technologically advanced processing, display, and telecommunications system that is the cornerstone of the United States National Weather Service 's (NWS) operations. [1]
3D radar provides for radar ranging and direction in three dimensions. In addition to range, the more common two-dimensional radar provides only azimuth for direction, whereas the 3D radar also provides elevation. Applications include weather monitoring, air defense, and surveillance. The information provided by 3D radar has long been required ...
Pulse-Doppler radar. A pulse-Doppler radar is a radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned signal to determine the target object's velocity. It combines the features of pulse radars and continuous-wave radars, which were formerly separate due to the complexity of ...
