NOAA Next Generation Radar (NEXRAD) Level III Products
Entry ID: gov.noaa.ncdc.C00708

Abstract: This dataset consists of Level III weather radar products collected from Next-Generation Radar (NEXRAD) stations located in the contiguous United States, Alaska, Hawaii, U.S. territories and at military base sites. 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 ...

Purpose: Level-II NEXRAD data include three meteorological base data quantities: reflectivity, mean radial velocity, and spectrum width. With the advent of dual polarization beginning in 2011, additional base products of differential reflectivity, correlation coefficient and differential phase are available. 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.
