CHSSDR-High Resolution (10km) Daily Surface Solar Diffuse Radiation Dataset in China during 1950-2020

This dataset of China's surface solar diffuse radiation is constructed by using the integrated model (generalized additive model, GAM). The reanalysis data deried from the ERA5 (European Center for medium range weather forecasts reanalysis) and the MERRA-2 (the modern era retrospective analysis for research and applications version 2) are used as the input parameters for the integrated model. This dataset has a daily average temporal resolution and a spatial resolution of 10km (0.1 degree), covering the whole area of China. The accuracy has been verified by using the surface diffuse solar radiation observation data at 17 stations of the China Meteorological Administration. Considering the large volume of this dataset, we only uploaded the CHSSDR data during 2010/1-2010/12. For complete data series during 1951-2020, please contact us via email ([e-mail]).

本数据集为中国地表太阳散射辐射数据集，采用集成模型——广义可加模型（generalized additive model, GAM）构建。模型输入参数取自ERA5 (European Center for medium range weather forecasts reanalysis)与MERRA-2 (the modern era retrospective analysis for research and applications version 2)的再分析资料。该数据集的时间分辨率为日平均，空间分辨率为10km（0.1°），覆盖中国全境。其精度已通过中国气象局17个站点的地表太阳散射辐射观测数据完成验证。鉴于本数据集体量较大，本次仅上传2010年1月至2010年12月的CHSSDR数据。如需获取1951-2020年的完整数据序列，请通过邮箱[e-mail]联系我们。
