2. Weather radar - Wikipedia

   en.wikipedia.org/wiki/Weather_radar

   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.).

3. Doppler radar - Wikipedia

   en.wikipedia.org/wiki/Doppler_radar

   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.

4. NEXRAD - Wikipedia

   en.wikipedia.org/wiki/NEXRAD

   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 ...

6. Terminal Doppler Weather Radar - Wikipedia

   en.wikipedia.org/wiki/Terminal_Doppler_Weather_Radar

   A NEXRAD weather radar currently used by the National Weather Service (NWS) is a 10 cm wavelength (2700-3000 MHz) radar capable of a complete scan every 4.5 to 10 minutes, depending on the number of angles scanned, and depending on whether or not MESO-SAILS [7] is active, which adds a supplemental low-level scan while completing a volume scan ...

7. List of radar types - Wikipedia

   en.wikipedia.org/wiki/List_of_radar_types

   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.

8. dBZ (meteorology) - Wikipedia

   en.wikipedia.org/wiki/DBZ_(meteorology)

   The scale of dBZ values can be seen along the bottom of the image. dBZ is a logarithmic dimensionless technical unit used in radar.It is mostly used in weather radar, to compare the equivalent reflectivity factor (Z) of a remote object (in mm 6 per m 3) to the return of a droplet of rain with a diameter of 1 mm (1 mm 6 per m 3).
