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.). Modern weather radars are mostly pulse-Doppler radars, capable of detecting the motion of rain droplets in addition to the intensity of the ...
Radar is a system that uses radio waves to determine the distance ( ranging ), direction ( azimuth and elevation angles ), and radial velocity of objects relative to the site. It is a radiodetermination method [ 1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
The Meteorological Office, abbreviated as the Met Office, [2] is the United Kingdom's national weather and climate service. It is an executive agency and trading fund of the Department for Science, Innovation and Technology and is led by CEO [3] Penelope Endersby, who took on the role as Chief Executive in December 2018 and is the first woman to do so.

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 ...
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. [3] [4] Weather radar; Wind profilers; Millimetre cloud radar ...
Royal Air Force Fylingdales or more simply RAF Fylingdales is a Royal Air Force station on Snod Hill in the North York Moors, England. Its motto is Vigilamus ("We are watching"). [ 1] It is a radar base and is also part of the Ballistic Missile Early Warning System (BMEWS). As part of intelligence-sharing arrangements between the United States ...
RRH Staxton Wold. / 54.18639°N 0.43444°W / 54.18639; -0.43444. Remote Radar Head Staxton Wold or RRH Staxton Wold is an air defence radar station operated by the Royal Air Force, located near Scarborough in North Yorkshire, England. [3] As it has been a radar site continuously since 1939, it has a claim to be the oldest working radar ...
