摘　　要：对晴空和有云情况进行了研究,用辐射理论导出了这两种情况下卫星测值和地表太阳总辐射、净辐射的关系,将卫星测值与地面辐射观测站的实测值进行拟合,建立了几种利用卫星测值估算地面太阳总辐射和净辐射的模式,经研究比较选出几种最佳模式。据此利用卫星资料估算晴空和有云情况下的太阳总辐射和净辐射,以弥补我国辐射测站稀少,资料短缺的不足。Clouds have important effect on the EarthAir system radiation budget.This paper investigates the relationship of satellite measurements with global radiation and net radiation in clear and cloudy skies by using radiation theory.We develop some models estimating global radiation and net radiation by using satellite data,and seperal best models of them are selscted.These models can be used to estimat the global and net radiation in clear sky and cloudy sky,thus remedying the stortage of radiation data.

关 键 词：云 卫星测值 太阳总辐射 净辐射
