Operational weather radar networks such as the Weather Surveillance Radar-1988 Doppler (WSR-88D) radar array, operated by the National Weather Service, and the Terminal Doppler Weather Radar
, operated by the Federal Aviation Administration, are invaluable for the monitoring of convection and turbulence.
It also includes updates on Direct User Access Terminal Service (DUATS II), Telephone Information Briefing Service (TIBS) and Terminal Doppler Weather Radar
(TDWR), and removes information regarding Area Forecasts (FA) for the continental U.S.
The next longer wavelengths are C-band (6,000 MHz, 5 cm), which were historically used for "storm warning radars" and are now used by TDWR (Terminal Doppler Weather Radar
) and TV station radars.
Accordingly, it is expected to construct Puttalam and Pottuvil Radar Tower Buildings to establish a Doppler Weather Radar
Network including C - band Pulse Compression Solid State Dual Polarization Doppler Meteorological Radar Systems, Meteorological Radar Central Processing System, Meteorological Radar Data Display Systems and Meteorological Data Communication Systems.
The velocity and range ambiguity  is still one of the major limitations for Doppler weather radar
According to the company, it had previously supplied HKIA with a Terminal Doppler Weather Radar
(TDWR), which detects wind shear and turbulence during precipitation by using microwave signals to measure the movement of rain drops in the atmosphere.
Takuo Kachiwa, department general manager at Furuno Electric, described a weather-radar system able to provide an advance warning to the onset of severe "gorilla thunderstorms." His team designed two compact X-band Doppler weather radar
systems, one of which weighs only 28 kg while offering a 30-km range and operating on less than 300 W of power.
KFOR-TV eventually became the first station in the country to introduce color Doppler weather radar
and in the 1990s, becoming the first television station to broadcast pictures and video of severe weather via cell phones.
Fabregas, "Analysis of wind turbines blockage on doppler weather radar
beams," IEEE Antennas Wireless Propagat.
has a long-established Doppler weather radar
system whose data is readily available through electronic distribution and two companies--WxWorx and WSI--further message the data into sophisticated products.
Under the contract Vaisala will deliver weather radar signal processors and software for the FAA Terminal Doppler Weather Radar
(TDWR) network, operating at major airports in the US.
Reports are generated by expert meteorologists using damage surveys and NEXRAD Doppler Weather Radar
