青海卫星订正太阳能资源分布图谱（2021-2024）

该数据为青海地区太阳能资源分布图谱。该数据基于风云卫星太阳辐射产品，借助国家气象辐射观测站辐射观测数据对其进行订正，并利用地形数据进行空间降尺度，形成空间分辨率1km,时间分辨率为逐小时的太阳辐射数据。数据集中包含总辐射、直接辐射、散射辐射。经全国164个地面辐射站检验，平均误差为-2.37 W/m2，均方根误差为129.71 W/m2，数据质量可靠，具有较好的时空连续性，可用于青海地区太阳能资源精细化评估。

This dataset is a solar resource distribution atlas for the Qinghai region. Developed based on solar radiation products from Fengyun (FY) satellites, this dataset was calibrated using radiation observation data collected at national meteorological radiation observation stations, and underwent spatial downscaling with terrain data to produce solar radiation data with a spatial resolution of 1 km and an hourly temporal resolution.
The dataset includes total radiation, direct radiation, and diffuse radiation.
Validated against 164 national ground-based radiation observation stations across China, the dataset has a mean error of -2.37 W/m² and a root mean square error (RMSE) of 129.71 W/m². It features reliable data quality and good spatiotemporal continuity, and is applicable for fine-grained assessment of solar resources in the Qinghai region.
