In 1995, KXII began utilizing "Doppler 12", a Doppler weather radar system based near the Madill transmitter site for use in weather forecast segments within its newscasts and severe weather cut-ins; the radar system integrates the data from KXII's radar with NEXRAD data from National Weather Service radars located near Dallas, Texas, Oklahoma ...

The CP2 Research radar was a 1970's era radar, which the BoM received as a gift from the NCAR in the United States. The BoM retrofitted it with modern parts which gave it the unique ability to collect data at two frequencies, S and X band. The upgrades also provided state of the art dual polarisation and doppler technologies.
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.).
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.
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). [1]
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 ...
In November 2005, KTEN began utilizing "TrueView Doppler 10/4" (later renamed "First Alert True View Radar" in 2012), a Doppler radar system that utilizes live VIPIR data from radars operated by National Weather Service radar sites out of Oklahoma City and Frederick, Oklahoma, Fort Worth, Texas and Shreveport, Louisiana for use by station ...
