The influence of underlying surface on reflectivity of layer atmosphere

The authors have considered the radiation transfer in triple dispersion media with reflective surface. The analytic for determining the values of reflectance and transmission coefficient of atmosphere consisting of three plane layers limited by the reflective surface were obtained. It was shown that stratosphere and bottom atmospheric layers even at low value of optical density and its weak change impact considerably the reflectance of the Atriple dispersion media - reflective surfaceA at all magnitudes of substrate on reflectivity. It was ascertained that the increase of elongation degree phase function in a cloud layer results reflectivity of the whole dispersion media. This effect is similar to reduction of optical density of atmosphere cloud layer.
