Maps, below, show existing radar locations and full volumetric coverage for all operation NEXRAD WSR-88D and TDWR sites. Beam heights were calculated using a standard atmospheric refractive index of 1.21 and the Half-Power Beamwidth.

Check out hundreds of maps and share custom maps! In 1988, the NEXRAD Agencies established the WSR-88D (Weather Surveillance Radar - 1988 Doppler) Radar Operations Center (ROC) in Norman, Oklahoma. The ROC employees come from the National Weather Service, Air Force, Navy, FAA, and support contractors.

NEXRAD (Next Generation Radar) stations obtain weather information (precipitation and wind) based upon returned energy. The radar emits a burst, or pulse, of energy. If the energy strikes an object (raindrop, snowflake, bug, bird, etc), the energy is scattered in all directions.

The NWS Radar site displays the radar on a map along with forecast and alerts. The radar products are also available as OGC compliant services to use in your application. Enhanced Radar Standard Radar (Low-Bandwidth)

Level-II and Level-III NEXRAD data include three meteorological base data quantities: reflectivity, mean radial velocity, and spectrum width as well as 40+ products generated using computer algorithms.
