青海地区基础太阳能资源分布图谱

该数据集为青海地区基础太阳能资源分布图谱，FY-4A SSI反演算法涉及的通道包括成像仪可见光、近红外和短波红外的6个通道，产品算法采用离散纵标法辐射传输软件包，在辐射传输计算的基础上，以AGRI短波范围多个反射通道的观测值作为输入及约束条件，反演得到瞬时地表太阳入射辐射值，时间分辨率逐小时，空间分辨率4km，利用中国气象局辐射观测站数据检验结果表明，数据集在青海地区相关系数可达0.7以上，适用于青海地区太阳能资源监测评估。

This dataset is a basic solar energy resource distribution atlas for the Qinghai region. The channels involved in the FY-4A SSI retrieval algorithm include 6 channels covering the imager's visible, near-infrared and short-wave infrared bands. The product algorithm adopts the discrete ordinate radiative transfer software package. Leveraging radiative transfer calculations, it retrieves the instantaneous surface solar incident radiation by using observations from multiple reflective channels in the short-wave range of AGRI as both input and constraints. This dataset has an hourly temporal resolution and a spatial resolution of 4 km. Validation using data from radiation observation stations of the China Meteorological Administration shows that its correlation coefficient in the Qinghai region exceeds 0.7, making it suitable for solar energy resource monitoring and assessment in the Qinghai region.
