中国逐月太阳辐射数据集v1.0（1970-2010年）

数据集为1970-2010年中国逐月太阳辐射数据，空间分辨率为1km，数据单位为MJ/m2。该数据集以中国716个气象站太阳辐射日均值数据集为基础，选取逐月降水量、气温、日照时数及DEM数据作为自变量，采用随机森林算法建模生成，验证结果可信。数据集地理空间范围是中国主要陆地（不含南海岛礁等区域）。数据为.tif格式，可直接用ArcMAP等空间分析软件打开与处理。该数据集可支撑全国及区域尺度的气候变化影响研究，为解析气候变化对陆地生态系统功能的作用机制及气候资源评估提供核心数据支撑。

This dataset provides monthly solar radiation data for China spanning 1970 to 2010, with a spatial resolution of 1 km and a data unit of MJ/m². It was developed based on the daily average solar radiation dataset from 716 meteorological stations across China, using monthly precipitation, air temperature, sunshine duration and DEM data as independent variables, and generated through the Random Forest algorithm, with reliable validation results. The geographic coverage of this dataset includes the main terrestrial areas of China (excluding regions such as the South China Sea islands and reefs). The data is stored in .tif format, and can be directly opened and processed using spatial analysis software such as ArcMap. This dataset can support climate change impact research at both national and regional scales, and offers core data support for analyzing the mechanisms through which climate change affects terrestrial ecosystem functions, as well as for climate resource assessment.
