NEXRAD is a network of 160 high-resolution Doppler weather radars operated by the NOAA National Weather Service (NWS), the Federal Aviation Administration (FAA), and the U.S. Air Force (USAF). Doppler radars detect atmospheric precipitation and winds, which allow scientists to track and anticipate weather events, such as rain, ice pellets, snow, hail, and tornadoes, as well as some non-weather objects like birds and insects. NEXRAD stations use the Weather Surveillance Radar - 1988, Doppler (WSR-88D) system. This is a 10 cm wavelength (S-Band) radar that operates at a frequency between 2,700 and 3,000 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 activity in the area, and a Precipitation Mode (Mode A) with a faster scan for tracking active weather. The two modes employ nine Volume Coverage Patterns (VCPs) to adequately sample the atmosphere based on weather conditions. A VCP is a series of 360 degree sweeps of the antenna at pre-determined elevation angles and pulse repetition frequencies completed in a specified period of time. The radar scan times 4.5, 5, 6 or 10 minutes depending on the selected VCP. During 2008, the WSR-88D radars were upgraded to produce increased spatial resolution data, called Super Resolution. The earlier Legacy Resolution data provides radar reflectivity at 1.0 degree azimuthal by 1 km range gate resolution to a range of 460 km, and Doppler velocity and spectrum width at 1.0 degree azimuthal by 250 m range gate resolution to a range of 230 km. The upgraded Super Resolution data provides radar reflectivity at 0.5 degree azimuthal by 250 m range gate resolution to a range of 460 km, and Doppler velocity and spectrum width at 0.5 degree azimuthal by 250 m range gate resolution to a range of 300 km. Super resolution makes a compromise of slightly decreased noise reduction for a large gain in resolution. In 2010, the deployment of the Dual Polarization (Dual Pol) capability to NEXRAD sites began with the first operational Dual Pol radar in May 2011. Dual Pol radar capability adds vertical polarization to the previous horizontal radar waves, in order to more accurately discern the return signal. This allows the radar to better distinguish between types of precipitation (e.g., rain, hail and snow), improves rainfall estimates, improves data retrieval in mountainous terrain, and aids in removal of non-weather artifacts. The NEXRAD products are divided in two data processing levels. The lower Level II data are base products at original resolution. Level II data are recorded at all NWS and most USAF and FAA WSR-88D sites. From the Level II quantities, computer processing generates numerous meteorological analysis Level III products. The Level III data consists of reduced resolution, low-bandwidth, base products as well as many derived, post-processed products. Level III products are recorded at most U.S. sites, though non-US sites do not have Level III products. There are over 40 Level III products available from the NCDC. General products for Level III include the base and composite reflectivity, storm relative velocity, vertical integrated liquid, echo tops and VAD wind profile. Precipitation products for Level III include estimated ground accumulated rainfall amounts for one and three hour periods, storm totals, and digital arrays. Estimates are based on reflectivity to rainfall rate (Z-R) relationships. Overlay products for Level III are alphanumeric data that give detailed information on certain parameters for an identified storm cell. These include storm structure, hail index, mesocyclone identification, tornadic vortex signature, and storm tracking information. Radar messages for Level III are sent by the radar site to users in order to know more about the radar status and special product data. NEXRAD data are provided to the NOAA National Climatic Data Center for archiving and dissemination to users. Data coverage varies by station and ranges from May 1992 to 1 day from present. Most stations began observing in the mid-1990s, and most period of records are continuous.\r\n \r\n \r\n NEXRAD Level III products are used to remotely detect atmospheric features, such as precipitation, precipitation-type, storms, turbulence and wind, for operational forecasting and data research analysis.\r\n \r\n \r\n \r\n \r\n \r\n NOAA National Centers for Environmental Information\r\n \r\n \r\n Customer Engagement Branch\r\n \r\n \r\n \r\n \r\n \r\n \r\n 1-828-271-4800\r\n \r\n \r\n 1-828-271-4876\r\n \r\n \r\n \r\n \r\n \r\n \r\n 151 Patton Avenue\r\n \r\n \r\n Veach-Baley Federal Building, Room 468\r\n \r\n \r\n Asheville\r\n \r\n \r\n NC\r\n \r\n \r\n 28801-5001\r\n \r\n \r\n USA\r\n \r\n \r\n ncei.orders@noaa.gov\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://www.ncei.noaa.gov\r\n \r\n \r\n HTTPS\r\n \r\n \r\n Web Browser\r\n \r\n \r\n NOAA National Centers for Environmental Information (NCEI)\r\n \r\n \r\n NCEI home page with information, data access and contact information.\r\n \r\n \r\n information\r\n \r\n \r\n \r\n \r\n 8:00 - 6:00 Eastern\r\n \r\n \r\n \r\n \r\n pointOfContact\r\n \r\n \r\n \r\n \r\n \r\n \r\n continual\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://www.ncei.noaa.gov/pub/data/metadata/images/C00708_fdr_baserefl.jpg\r\n \r\n \r\n NEXRAD reflectivity image\r\n \r\n \r\n JPEG\r\n \r\n \r\n \r\n \r\n \r\n \r\n Earth Science > Spectral/Engineering > Radar > Doppler Velocity\r\n \r\n \r\n Earth Science > Spectral/Engineering > Radar > Radar Cross-Section\r\n \r\n \r\n Earth Science > Spectral/Engineering > Radar > Radar Reflectivity\r\n \r\n \r\n Earth Science > Spectral/Engineering > Radar > Spectrum Width\r\n \r\n \r\n Earth Science > Spectral/Engineering > Sensor Characteristics > Viewing Geometry\r\n \r\n \r\n Earth Science > Human Dimensions > Natural Hazards > Tropical Cyclones > Typhoons\r\n \r\n \r\n Earth Science > Atmosphere > Weather Events > Tropical Cyclones\r\n \r\n \r\n Earth Science > Atmosphere > Weather Events > Hurricanes\r\n \r\n \r\n Earth Science > Atmosphere > Weather Events > Rain Storms\r\n \r\n \r\n Earth Science > Atmosphere > Weather Events > Tornados\r\n \r\n \r\n Earth Science > Atmosphere > Atmospheric Winds > Upper Level Winds > Boundary Layer Winds\r\n \r\n \r\n Earth Science > Atmosphere > Atmospheric Winds > Upper Level Winds > Wind Speed\r\n \r\n \r\n Earth Science > Atmosphere > Atmospheric Winds > Upper Level Winds > Wind Direction\r\n \r\n \r\n Earth Science > Atmosphere > Atmospheric Winds > Wind Profiles\r\n \r\n \r\n Earth Science > Atmosphere > Atmospheric Winds > Wind Dynamics > Vertical Wind Velocity/Speed\r\n \r\n \r\n Earth Science > Atmosphere > Atmospheric Winds > Wind Dynamics > Wind Shear\r\n \r\n \r\n Earth Science > Atmosphere > Atmospheric Winds > Wind Dynamics > Convection\r\n \r\n \r\n Earth Science > Atmosphere > Clouds > Cloud Microphysics > Cloud Liquid Water/Ice\r\n \r\n \r\n Earth Science > Atmosphere > Clouds > Convective Clouds/Systems (observed/Analyzed) > Mesoscale Convective Complex\r\n \r\n \r\n Earth Science > Atmosphere > Precipitation > Precipitation Amount\r\n \r\n \r\n Earth Science > Atmosphere > Precipitation > Precipitation Rate\r\n \r\n \r\n Earth Science > Atmosphere > Precipitation > Liquid Precipitation > Rain\r\n \r\n \r\n Earth Science > Atmosphere > Precipitation > Solid Precipitation > Snow\r\n \r\n \r\n Earth Science > Atmosphere > Precipitation > Solid Precipitation > Hail\r\n \r\n \r\n Earth Science Services > Environmental Advisories > Hydrological Advisories > Floods\r\n \r\n \r\n Earth Science Services > Environmental Advisories > Weather/Climate Advisories > Severe Weather\r\n \r\n \r\n theme\r\n \r\n \r\n \r\n \r\n Global Change Master Directory (GCMD) Science Keywords\r\n \r\n \r\n \r\n \r\n 2018\r\n \r\n \r\n revision\r\n \r\n \r\n \r\n \r\n Version 8.6\r\n \r\n \r\n \r\n \r\n Global Change Data Center, Science and Exploration Directorate, Goddard Space Flight Center (GSFC) National Aeronautics and Space Administration (NASA)\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://earthdata.nasa.gov/about/gcmd/global-change-master-directory-gcmd-keywords\r\n \r\n \r\n HTTPS\r\n \r\n \r\n Web Browser\r\n \r\n \r\n Global Change Master Directory (GCMD) Keywords\r\n \r\n \r\n The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.

From these Level II data, computer processors generate numerous meteorological analysis Level III products based on the Level III product algorithms. Level II data are recorded at all NWS and several select CONUS DOD WSR-88D sites. Level III products are recorded at all U.S. sites.
