GPM Ground Validation Validation Network (VN) V1

The GPM Ground Validation Validation Network (VN) dataset contains reflectivity, hydrometeor identification, rain rate, correlation coefficient, and quality control variables and estimates. This data product was created using the Validation Network (VN), which performs a direct match-up of the Global Precipitation Mission (GPM)’s space-based Dual-frequency Precipitation Radar (DPR) and Microwave Imager (GMI) data with ground radar data from NOAA Weather Surveillance Radar-1988 Doppler (WSR-88D) radars. These data are available from March 9, 2014 through July 31, 2021 in netCDF-3 format, though it should be noted that this dataset will be updated periodically.
