Application of series of exponents in calculations of radiation transfer in spatially inhomogeneous aerosol and gaseous media by the Monte-Carlo method
A method for consideration of the molecular absorption when solving the radiation transfer equation in spatially inhomogeneous aerosol and gaseous media by the Monte-Carlo method is considered. The method is based on the expansion of the broadband transmission function in a series of exponents. The applicability of series of exponents to the spatially inhomogeneous atmosphere is analyzed both theoretically and numerically. The results of numerical modeling have demonstrated a high efficiency of the given method: the computational time decreased more than 102 times compared to the line-by-line method, and the discrepancy of the results obtained was less than 0.2%.
