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.).
3D nowcasting refers to an experimental technology of nowcasting in meteorology that uses a rapid phased-array radar to predict precipitation several minutes in advance. [1] The phased-array radar takes a scan of the sky in anywhere from 10–30 seconds, viewing 100 vertical levels in a range of 60 km. [2] thus providing inputs every 30 seconds.
General purpose radars are increasingly being substituted for pure navigational radars. These generally use navigational radar frequencies, but modulate the pulse so the receiver can determine the type of surface of the reflector. The best general-purpose radars distinguish the rain of heavy storms, as well as land and vehicles.
