Abstract
An attempt has been made to use satellite radiation measurements for the determination of the temporal and spatial variability of two cloudiness parameters, which are closely related with the radiation budget of the Earth-atmosphere system. On the basis of two sets of experimentally determined values of the planetary albedo the monthly mean cloud amount distribution has been estimated in the latitudinal belt between 60°N and 60°S. For this purpose the realistic values of the ground albedo have been used, and the cloud albedo was assumed to be dependent only on the solar zenith angle. A harmonic analysis has been undertaken for the cloud amount distribution over the latitudinal belt from 30°N to 30°S. It has been shown that nine harmonics can be used for an adequate description of the temporal-spatial variability of cloudiness. The mean monthly zonal values of cloud top temperature and of the cloud top height over the tropical oceans have been estimated on the basis of the experimental values of outgoing longwave flux. For this task the monthly mean sea surface temperatures have been used. The transfer of longwave radiation has been described by means of the integral transmission functions for water vapour and carbon dioxide.
