North Little Rock is in charge of weather forecasts, warnings and local statements as well as aviation weather. The name of the Doppler weather radar (WSR-88D) code used by this office is LZK. The National Weather Service at North Little Rock, Arkansas programs 12 NOAA Weather Radio transmitters across Arkansas, with 25 transmitters statewide.
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 ...
Synthetic-aperture radar ( SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. [1] SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam-scanning radars.
Part of the tornado outbreaks of 2023 and 2022–23 North American winter. A widespread, deadly, and historic [3] tornado outbreak affected large portions of the Midwestern, Southern and Eastern United States on March 31 and April 1, 2023, the result of an extratropical cyclone that also produced blizzard conditions in the Upper Midwest.
Air Route Surveillance Radar. The Air Route Surveillance Radar is a long-range radar system. It is used by the United States Air Force and the Federal Aviation Administration to control airspace within and around the borders of the United States. The ARSR-4 is the FAA's most recent (late 1980s, early 1990s) addition to the "Long Range" series ...
Type 512 Radar navigational/surface search radar. Type 514 Radar air search radar. Type 515 Radar 'BEAN/PEA STICK'air/surface search radar. Type 517 Radar 'KNIFE REST' air/surface search. Type 518 Radar air search radar. Type 707 Radar 'FIN CURVE' navigation radar.
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.
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 ...
