摘　　要：风云四号(FY-4A)可提供高时空和光谱分辨率的观测数据,在太阳能资源评估领域具有巨大潜力。本文利用FY-4A可见光通道观测数据和半经验模型建立了分辨率为4 km和15 min的水平面总辐射(FY-GHI)数据集。结果显示,逐时FY-GHI的相关系数(R)、均方根误差(RMSE)、平均偏差(MBE)分别为0.90、118.8 W/m^(2)和2.2 W/m^(2)。太阳能资源空间分布结果表明,青藏高原、中国北部和西北地区具备充沛的太阳能资源,中国西南地区和东北地区的太阳能资源相对匮乏。Fengyun-4(FY-4A)can provide high spatial-temporal and spectral resolution observa-tion data,and has great potential in the field of solar energy resource assessment.In this paper,a total horizontal radiation(FY-GHI)dataset with a resolution of 4 km and 15 minutes is established by using FY-4A visible light channel observation data and semi empirical model.The results show that the correlation coefficient(R),root mean square error(RMSE)and mean deviation(MBE)of hourly FY-GHI were 0.90,118.8 W/m^(2) and 2.2 W/m^(2),respectively.The results of spatial distri-bution of solar energy resources show that the Qinghai Tibet Plateau,northern and northwestern China have abundant solar energy resources,while the southwest and northeast China are relatively scarce.
