Google Earth Engine——气候危害组红外降水与站点数据（CHIRPS）是一个30年以上的全球降水数据集
Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) is a 30+ year quasi-global rainfall dataset. CHIRPS incorporates 0.05° resolution satellite imagery with in-situ station data to create gridded rainfall time series for trend analysis and seasonal drought monitoring.
气候危害组红外降水与站点数据（CHIRPS）是一个30年以上的准全球降水数据集。CHIRPS结合了0.05°分辨率的卫星图像和原位站数据，形成网格化的降雨时间序列，用于趋势分析和季节性干旱监测。
