Abstract

We present a statistical algorithm for calculating the mean intensity of reflected solar radiation in limb sensing geometry taking into account the effects of the stochastic geometry of liquid-water clouds. It is shown that the 3D cloud effects determine the main regularities of the formation of solar radiation brightness fields when changing a perigee height from the level of the underlying surface to the cloud top. A comparison of the intensities in the clear sky, overcast and broken clouds for different perigee heights and illumination conditions is carried out (visible range).
