Calculation of Single Scattering Parameters in Vector Radiative Transfer Equation
Based on Mie theory, the single scattering characteristics of a cluster of polydisperse spherical aerosols are calculated. The size distribution of particles is Gamma distribution and effective radii are 5.56, 7, 11 μm, respectively. The average extinction coefficients, average scattering coefficients, single scattering albedos, asymmetry parameters and elements of single scattering phase matrix in the spectral range of 0.4~100 μm are analyzed. The numerical results show that the single scattering properties of aerosols are seldom affected by particle effective radius in visual light waveband, but greater at higher waveband. The single scattering albedo approximately equals 1 at visual light waveband and the characteristics of single scattering albedo are opposite to the imagery part of refraction index. The polarization ratios of single scattering phase matrix are more sensitive to particle size than phase functions.
