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 ...
Map shows rising wildfire threat across the U.S.: See if you're affected A combination of hotter and drier weather and more people living in places that naturally burn are making things complicated.
Ivan Brunk, meteorologist in charge of the Chicago U.S. Weather Bureau (now National Weather Service) office at that time, suggested that the radio service be reinstated and put to Marine usage on an experimental basis. The marine weather broadcast was an immediate success, and the service became permanent two years later.
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.).
Doppler on Wheels (or DOW) is a fleet of X-band and C-band mobile and quickly-deployable truck-borne radars which are the core instrumentation of the Flexible Array of Radars and Mesonets [1] affiliated with the University of Alabama Huntsville [2] and led by Joshua Wurman, with the funding partially provided by the National Science Foundation ...
A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. [1] It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal.
Indianapolis Center is depicted in the second scene of Steven Spielberg's Close Encounters of the Third Kind (1977), in which an air traffic controller provides information and guidance to pilots of two passenger jets (Trans World Airlines, Allegheny Airlines and a fictional "Air East") who are en route through the ZID flight information region to avoid collisions with each other or with an ...
Once the radar can "look down", it is subsequently desirable to "shoot down". Various weapons systems (including guns and missiles) are then employed against designated radar targets, either relying on the aircraft's radar employing the "look down" capability (as in semi-active radar homing) or the weapon's own active radar to resolve the indicated target (as in active radar homing).
