The existing models for forecasting hourly total solar irradiance are unsatisfactory in forecast errors and the generalization capability. 现有的地面太阳逐时总辐射预测模型的预测精度及泛化能力尚不能令人满意。
In contrast, high-altitude organic haze absorbs incoming sunlight and reradiates it back into space, thereby reducing the total amount of radiation that reaches the surface. 相对之下，高纬度区的有机霾吸收入射的日光，并将其再辐射回太空中，使地表接受的总辐射量因而降低。
Total radiation instruments employ some broad spectral band sensors. 全辐射仪器要使用某些宽频带传感器。
