The DOW program rapidly expanded and evolved to include the first mobile dual-Doppler weather radar network, the first mobile rapid-scan radar (the Rapid-Scan DOW, RSDOW), [1] and the first quickly-deployable 1-degree C-band radar, the C-band on Wheels (COW).
The scale of dBZ values can be seen along the bottom of the image. Decibel relative to Z, or 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).

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 ...
New York City woke up to its first white Christmas in 15 years. But only a few areas of the U.S. are likely to see snow in the weather forecast for Christmas 2024.

The Rapid X-band Polarimetric Radar, commonly abbreviated as RaXPol, [1] is a mobile research radar designed and operated by the University of Oklahoma, led by Howard Bluestein. RaXPol often collaborates with adjacent mobile radar projects, such as Doppler on Wheels and SMART-R . [ 2 ]
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 ...
Severe weather jolted parts of Texas and Louisiana on Thursday and Thursday night, spinning up multiple tornadoes to kick off a stretch of stormy weather for the Gulf Coast states. Two tornadoes ...
