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.

GPM 地面验证验证网络（VN）数据集包含了反射率、水汽粒子识别、降雨速率、相关系数以及质量控制变量和估计值。该数据产品通过验证网络（VN）创建，该网络直接匹配全球降水任务（GPM）的基于空间的双频降水雷达（DPR）和微波成像仪（GMI）数据与国家海洋和大气管理局（NOAA）天气监视雷达-1988多普勒（WSR-88D）雷达的地面雷达数据。这些数据以 netCDF-3 格式从2014年3月9日到2021年7月31日可用，尽管应指出，该数据集将定期更新。
