Radiative Transfer in Homogeneous Nongray Gases With Nonisotropic Particle Scattering

A perturbation technique is presented to treat the problem of radiative transfer in homogeneous, plane parallel, nongray gases with nonisotropic particle scattering. The technique allows use of nongray narrow-band or wide-band models as well as Mie and Rayleigh scattering coefficients and asymmetry factors. Results are obtained in the form of monochromatic transmittance, reflectance, and absorptance of water clouds typical of those in the earth’s atmosphere.
