（2）数据构建过程中的算法说明
模型发展：基于辐射传输理论，并通过考虑太阳光到达地表过程的各种衰减因子，发展了适合于卫星遥感的纯物理参数化反演方案。
模型输入：融合全球静止卫星和极轨卫星各种产品，如云光学参数、大气含水量、臭氧含量、高程、气溶胶光学厚度、反照率等模型输入格点数据。
模型输出：将制备好的输入数据带入反演模型，估算出总辐射和散射辐射，并根据经纬度和时间排序，形成纬度*经度（1800*3600）的数组，即地表太阳辐射数据集。
数据应用：地表过程模拟和太阳能工程应用的最基础的输入数据。

This dataset can be used for photovoltaic (PV) and concentrated solar power (CSP) generation potential simulation in the solar energy domain, as well as for other solar engineering applications, hydrological modeling, surface modeling, and other related scenarios.
1) Data Usage and Algorithm Instructions:
The dataset stores both global horizontal total solar radiation and diffuse solar radiation data. Each file is a netCDF (.nc) file containing a 3600×1800 array, which can be read using scientific computing software such as MATLAB or Python. The two dimensions correspond to longitude and latitude, respectively. Each file corresponds to a specific time (year, month, day, and hour), with the time information embedded in the filename. The longitude range of the dataset is 0° to 360°, with an interval of 0.1° (approximately 10 km), resulting in 3600 longitude grid points. The latitude range spans from 90°N to 90°S, with an interval of 0.1° (approximately 10 km), totaling 1800 latitude grid points. There are 365×24 or 366×24 files per year, all following the 3600×1800 array structure.
2) Algorithm Description for Data Construction:
Model Development: A purely physical parametric inversion scheme suitable for satellite remote sensing was developed based on radiative transfer theory, by considering various attenuation factors during the propagation of sunlight to the Earth's surface.
Model Inputs: Grid-point input data for the model are fused from various products of global geostationary and polar-orbiting satellites, including cloud optical parameters, atmospheric water vapor content, ozone content, elevation, aerosol optical depth (AOD), albedo, and other relevant parameters.
Model Outputs: The prepared input data are fed into the inversion model to estimate total solar radiation and diffuse solar radiation, which are then sorted by latitude, longitude, and time to form a latitude×longitude (1800×3600) array, constituting the surface solar radiation dataset.
Data Application: This dataset serves as the most fundamental input data for surface process simulation and solar energy engineering applications.
