Abstract
Relations and calculation results are presented for determining the effective thickness of the deposited water vapor layer and the effective optical path length adjusted by the absorption capacity of carbon dioxide to the surface layer, taking into account the sphericity of the earth's surface for the operation of infrared optoelectronic systems on slant paths at elevation angles of less than 20°.
