GPM GROUND VALIDATION KCXX NEXRAD GCPEX V1

The GPM Ground Validation KCXX NEXRAD GCPEx dataset was collected during January 9, 2012 to March 12, 2012 for the GPM Cold-season Precipitation Experiment (GCPEx). GCPEx addressed shortcomings in GPM snowfall retrieval algorithm by collecting microphysical properties, associated remote sensing observations, and coordinated model simulations of precipitating snow. These data sets were collected toward achieving the overarching goal of GCPEx which is to characterize the ability of multi-frequency active and passive microwave sensors to detect and estimate falling snow. The Next Generation Weather Radar system (NEXRAD) is comprised of 160 Weather Surveillance Radar-1988 Doppler (WSR-88D) sites throughout the United States and select overseas locations. The GPM Ground Validation NEXRAD GCPEx data files are available as level 2 binary files and level 3 compressed binary files.

GPM 地面验证 KCXX NEXRAD GCPEx 数据集于 2012 年 1 月 9 日至 3 月 12 日期间，为 GPM 冷季降水实验（GCPEx）而收集。GCPEx 通过收集微物理特性、相关的遥感观测数据以及降水雪的协调模型模拟，旨在解决 GPM 雪量检索算法的不足。这些数据集的收集旨在实现 GCPEx 的总体目标，即描述多频段主动和被动微波传感器检测和估计下雪能力。下一代天气雷达系统（NEXRAD）由遍布美国及海外选定位置的 160 个天气监视雷达-1988 多普勒（WSR-88D）站点组成。GPM 地面验证 NEXRAD GCPEx 数据文件以第 2 级二进制文件和第 3 级压缩二进制文件的形式提供。
