利用风云二号(FY-2D)和风云三号(FY-3A)气象卫星上搭载的可见光辐射自旋扫描分析仪和中分辨率光谱成像仪等传感器数据,基于大气辐射传输原理建立地面太阳直射与散射辐射反演模型,并用来对新疆地区每小时的直射和散射太阳辐射能进行估算;再用地面气象观测站点数据对反演结果进行精度评价。结果表明,所提出的方法能较好地估算新疆地区高时间分辨率的地表太阳辐射,为该区域太阳能资源的利用提供基础数据支撑。
Based on the sensor data of visible radiation scanning scanners and mid-resolution spectral imagers mounted on the FY-2D and FY-3A meteorological satellites, ground-based direct solar radiation And scattering radiation inversion model, and used to estimate the hourly direct and scattered solar radiation energy in Xinjiang. The accuracy of the inversion results was then evaluated using the meteorological observation site data. The results show that the proposed method can better estimate the temporal resolution of surface solar radiation in Xinjiang and provide basic data support for the utilization of solar energy resources in this region.
