Calculation of Thermal Emission from Aerosols Using the Doubling Technique.

Abstract

The doubling approach to numerically solving the equation of radiative transfer in a plane-parallel atmosphere is reviewed and extended to include thermal emissions from an ambient medium. The matrix method used is that of Barkstrom and Querfeld and employs the familiar S and T operators to construct a thermal emission operator, E. This new operator is not internally dependent upon the temperature of the layer under consideration, thereby providing a computationally fast method for producing atmospheric models in which thermal emission effects are included. The method is further extended to include the effects of the clear air layer below a cloud base and also the effects of emission from the planetary surface. A computer program using this method is described and results of studies of clouds and smoke are given. (Author)
