Radar data and derived products are available at no cost through the National Climatic Data Center (NCDC). The system from which these data are collected is the Weather Surveillance Radar-1988 Doppler network (WSR-88D Radar) which began operation at a few sites in 1991 and now comprises numerous Weather Surveillance Radar sites throughout the United States and select overseas locations.
Level II data are the three meteorological base data quantities: reflectivity, mean radial velocity, and spectrum width. From these quantities, computer processing generates numerous meteorological analysis products known as Level III data. Level II data are recorded at all NWS and several select CONUS DOD WSR-88D sites. Level III products are recorded at most NEXRAD sites. The data are sent to the National Climatic Data Center (NCDC) for archiving and dissemination. Detailed information can be found at the NEXRAD Radar Operations Center. Radar details
