2018-2020年东亚0.1度高时空分辨率逐时降水数据

2018-2020年东亚高时空分辨率降水数据集通过风云二号静止卫星红外资料和多极轨卫星微波降水的融合，生成了覆盖风云二号全圆盘范围的降水资料，进一步利用我国的加密雨量计站观测提高了我国陆面范围的雨量估计精度，形成了时空分辨率和精度都较高的综合的定量降水估计产品。

The 2018–2020 East Asian high-spatiotemporal-resolution precipitation dataset was developed by fusing infrared data from Fengyun-2 (FY-2) geostationary satellites and microwave precipitation retrievals from multiple polar-orbiting satellites, producing precipitation datasets covering the full disk of FY-2 satellites. Furthermore, dense national rain gauge observations were utilized to enhance the accuracy of rainfall estimation over China’s terrestrial areas, ultimately yielding a comprehensive quantitative precipitation estimation (QPE) product with excellent spatiotemporal resolution and accuracy.
