GPM Ground Validation Dual-frequency Dual-polarized Doppler Radar (D3R) ICE POP

The GPM Ground Validation Dual-frequency Dual-polarized Doppler Radar (D3R) ICE POP dataset includes reflectivity, differential reflectivity, copolar correlation coefficient, differential propagation phase, radial velocity, and spectrum width data collected by the Dual-frequency Dual-polarized Doppler Radar (D3R) during the International Collaborative Experiments for Pyeongchang 2018 Olympic and Paralympic Winter Games (ICE-POP) field campaign in South Korea. The two major objectives of ICE-POP were to study severe winter weather events in regions of complex terrain and improve the short-term forecasting of such events. These data contributed to Global Precipitation Measurement mission Ground Validation (GPM GV) campaign efforts to improve satellite estimates of orographic winter precipitation. The D3R was developed by a government-industry-academic consortium with funding from NASA's GPM Project. It operates at the ku (13.91 GHz ± 25 MHz) and ka (35.56 GHz ± 25 MHz) frequencies covering a fixed range from 450 m to 39.75 km. The D3R dataset files are available from November 1, 2017 through March 17, 2018 in netCDF-4 format.

GPM 地面验证双频双偏振多普勒雷达（D3R）ICE POP 数据集，收录了在韩国举行的国际协作实验——平昌2018年冬季奥运会和残奥会（ICE-POP）野外考察活动中，由双频双偏振多普勒雷达（D3R）收集的反射率、差分反射率、共极相关系数、差分传播相位、径向速度和谱宽数据。ICE-POP 的两大目标为研究复杂地形区域的极端冬季天气事件，并提升此类事件的短期预报精度。这些数据为全球降水测量任务地面验证（GPM GV）活动贡献力量，旨在优化卫星对地形冬季降水的估计。D3R 由政府、产业和学术界联合研发，并由美国国家航空航天局（NASA）的GPM项目资助。该雷达在ku（13.91 GHz ± 25 MHz）和ka（35.56 GHz ± 25 MHz）频段运行，覆盖固定距离范围450米至39.75公里。D3R 数据集文件以netCDF-4格式提供，可供下载的时间范围从2017年11月1日至2018年3月17日。
