2018-2020年全球0.25度降水逐月数据

全球降水数据是依据FY-3D MWRI轨道观测数据及辅助数据生成瞬时地面降水率，继而通过等经纬度投影及月平均处理后得到的全球格点月平均降水率。数据集时间跨度为2018-2020，时间分辨率为月，空间分辨率为0.25o×0.25o，数据单位为mm/h。该数据是风云三号气象卫星首次发布的气候降水数据，对于理解全球水循环至关重要。

This global precipitation dataset is generated by first deriving instantaneous surface precipitation rates from FY-3D MWRI orbital observation data and auxiliary datasets, then conducting equirectangular projection and monthly averaging to produce global gridded monthly mean precipitation rates. The dataset spans the period from 2018 to 2020, featuring a monthly temporal resolution and a spatial resolution of 0.25° × 0.25°, with the data unit being mm/h. This is the first climatic precipitation dataset released by the Fengyun-3D meteorological satellite, which is critically important for advancing the understanding of the global water cycle.
