Abstract

The problem of calculating the brightness coefficient of sunlight reflected from the atmosphere in the presence of spatially local horizontal inhomogeneities (property discontinuity surfaces) of a medium (where one-dimensional mathematical models, traditionally used in such calculations, cannot be applied) is considered. A two-dimensional mathematical model, which makes it possible to obtain the detailed spatial distribution of the brightness coefficient in the vicinity of an inhomogeneity, has been proposed and used to obtain the characteristic distributions in a model problem. It has been proposed to use a quasione-dimensional model to effectively estimate the extension of a subregion including an inhomogeneity, outside of which multidimensional effects in the brightness coefficient can be neglected, and this model has been numerically tested.
