GPM Ground Validation Precipitation Imaging Package (PIP) ICE POP V1

The GPM Ground Validation Precipitation Imaging Package (PIP) ICE POP dataset includes precipitation measurements and video images collected by the Precipitation Imaging Package (PIP) 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 the Global Precipitation Measurement mission Ground Validation (GPM GV) campaign efforts to improve satellite estimates of orographic winter precipitation. Data values obtained using PIP measurements include particle size distributions, fall velocity distributions, precipitation density estimates, and precipitation rates. The dataset files are available from June 18, 2017 through December 30, 2018 as generic data files (.dat) in ASCII-CSV format with browse imagery and video available in PNG and AVI format.

GPM 地面验证降水成像包（PIP）ICE POP 数据集包含了在韩国首尔举行的第24届冬季奥林匹克和残奥会（ICE-POP）国际协作实验期间，通过降水成像包（PIP）收集的降水测量数据和视频图像。ICE POP 的两大目标是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）活动作出了贡献，旨在改善对地形冬季降水的卫星估算。利用 PIP 测量获得的数据值包括颗粒尺寸分布、沉降速度分布、降水密度估计和降水速率。数据集文件自2017年6月18日至2018年12月30日提供，以 ASCII-CSV 格式的通用数据文件（.dat）形式，同时提供 PNG 和 AVI 格式的浏览图像和视频。
