Abstract
A statistical method for retrieving the clear radiance from several adjacent fields of view of HIRS/2 which are partially contaminated by clouds is developed using the digital picture data of AVHRR on TIROS-N satellites. The accuracy of this method is compared with that of McMillin's method by simulation study. The error of the present method is about 2/5 that of McMillin's method.The two methods are also applied to the actual data of radiances observed by satellite and the conclusions obtained in the simulation study are again confirmed.
