Abstract

A method of calculating the self-radiance of the sky based on LOWTRAN-4 computer code is described. The method is a significant improvement on that included as an option in LOWTRAN 4 itself as a result of two modifications: a) Our method, unlike the one included in LOWTRAN 4, takes into account the radiance scattered into the line of sight. b) The model of the atmosphere in the computer code must be divided into a certain number of layers each one having approximately uniform conditions. Our method uses a correct optimal division. Consequently, our method gives a better agreement with the experimental data, especially for long optical paths in the lower layers of the atmosphere.
