Congress. House. Committee on Science, Space, and Technology. A major part of the modernization of the National Weather Service (NWS) in the s was the installation of a national network of Next Generation Radar [NEXRAD; Weather Surveillance Radar Doppler (WSRD)] weather radars.

1 The radars use a Doppler-pulse signal and were adapted for weather applications through a cooperative effort by the Cited by: The National Weather Service was so impressed by the warning potential of these Doppler velocity signatures, that it joined with the Federal Aviation Administration, the Air Force’s Air Weather Service, and National Severe Storms Laboratory in the Joint Doppler Operational Project,to test the radar's ability to improve tornado warnings.

Weather radar furnishes essential observations of the atmosphere used in providing weather forecasts and issuing weather warnings to the public.

The primary weather surveillance radar system operated by U.S. agencies is the WSRD (NEXRAD) system, which consists of about nearly identical radars. Eight year national plan for the modernization and restructuring of the National Weather Service is announced. The massive $ billion overhaul of the agency from will last a decade and change the way the agency operates, resulting in improved capabilities to protect lives and livelihoods.

The impact of the installation of Weather Surveillance Radar Doppler (WSRD) radars in the s on the quality of tornado warnings and occurrence of tornado casualties is examined. Weather radar is a vital instrument for observing the atmosphere to help provide weather forecasts and issue weather warnings to the public.

The current Next Generation Weather Radar (NEXRAD) system provides Doppler radar coverage to most regions of. The National Weather Service got deeper into IDSS and Social media. From a technology perspective, the implementation of GOES into operations was a and National Weather modernization book project in the timeframe.

NEXRAD is a network of high-resolution Doppler weather radars operated by the NOAA National Weather Service (NWS), the Federal Aviation Administration (FAA). NEXRAD stations use the Weather Surveillance Radar -Doppler (WSRD) system. This is a 10 cm wavelength (S-Band) radar that operates at a frequency between 2, and 3, MHz.

The radar system operates in two basic modes: a slow-scanning Clear Air Mode (Mode B) for analyzing air movements when there is little or no precipitation Publish Year:   Upgraded radar could allow the National Weather Service to detect tornadoes more quickly and get the warning out sooner.

(July 6, )). The current Next Generation Weather Radar (NEXRAD) system provides Doppler radar coverage to most regions of the United States (NRC, ).
