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 Radar Operations Center (ROC) is a National Weather Service (NWS) unit that coordinates the development, maintenance, and training for the NEXRAD weather radar network. [1]
By and large, meteorological monitoring is done operationally by relatively legacy weather radar systems – in the United States, the NEXRAD network has been the primary weather radar network since the early 1990s. For the first 20 years of operations, its data output was, in comparison to modern schemes, considerably more modest.
The office is in charge of weather forecasts, warnings and local statements as well as aviation weather. It is also equipped with a WSR-88D (NEXRAD) radar, and an Automated Surface Observing System (ASOS) that greatly increase the ability to forecast.
The Langley Hill Doppler radar (KLGX) is a National Weather Service NEXRAD Doppler weather radar station on the Pacific coast of Washington State, in the United States. Prior to its construction, Washington's Olympic Peninsula coast was the only portion of the U.S. coastline without weather radar coverage, and "virtually no radar coverage [is] available over the ocean, where the majority of ...
NSSL's first Doppler weather radar, the NSSL Doppler, located in Norman, Oklahoma. 1970s research using this radar led to NWS NEXRAD WSR-88D radar network. The first tornado captured on May 24, 1973, by the NSSL Doppler weather radar and NSSL chase personnel. The tornado is here in its early stage of formation near Union City, Oklahoma
Richard James Doviak was an American engineer and university professor, pioneer of weather radar.He worked for the National Oceanic and Atmospheric Administration at the National Severe Storms Laboratory developing the NEXRAD radar array using reflectivity, the Doppler effect and the dual polarization to detect precipitation and its movement in clouds.
