摘要
利用1994年6月、7月上海和北京地区08—17时地面观测资料及同期GMS卫星红外、可见光数字云图资料,用统计的方法讨论了地表净辐射与卫星测值之间的关系,建立了用卫星资料计算08—17时各时刻地表净辐射和08—17时总地表净辐射的估算模式,并分别以1994年7月1日14时的云图和济南地区为例作了检验。结果表明用卫星数字云图资料估算地面08—17时各时刻地表净辐射和08-17时总地表净辐射是可行的。
In this paper,the relationship between surface net radiation and satellite data is statistically discussed by use of the surface radiation observations and the Visible.Infrared data set from GMS4 at the same time over Shanghai and Beijing area in June and July 1994,and the regression prediction equations are developed for estimating 0800—1700 hourly surface net radiation and 0800—1700 total surface net radiation.And the two models are tested for 1400 1st July 1994 and Jinan area respectively.The result shows that it is feasible to estimate the surface net radiation by use of the satellite cloud picture.
