Solar Radiation Scattering by Aerosol Axially Symmetric Objects

We have obtained analytical expressions for the scattering coefficient and the angular distribution of radiation for the aerosol train (tail) modeled by a homogeneous cylinder with given scattering coefficient and phase function of the elementary volume. The analytical formulas for the angular distribution of scattered radiation have been obtained in the single-scattering approximation. Using the Monte Carlo method, we have calculated the directional scattering coefficients of a homogeneous monodisperse tail consisting of spherical water particles with a mean radius of 1 μm for various diametrical optical thicknesses of the tail. The relations obtained can be used for passive remote sensing of aerosol air pollutions. __________ Translated from Zhurnal Prikladnoi Spektroskopii, Vol. 72, No. 5, pp. 604–610, September–October, 2005.
