Characteristics of atmospheric volume scattering intensity in visible and infrared band
可见光和红外波段大气体散射强度特性

Different size distributions of aerosol, fog and rain collected. Atmospheric volume scattering intensity characteristics were calculated and analyzed according to Mie scattering theory. The results show that the energy of atmospheric volume scatter concentrated mainly in a narrow area of forward scatter angle. The distributions of volume scattering phase relied on particle size distributions, wavelength and complex refraction index, and was diverse for different type of particles. The atmospheric single scattering albedo was influenced by the wavelength and the imaginary of complex refractive index, and varied in a wide value range. The single scattering albedo of urban aerosols was less than that of fogs in the same wavelength. The single scattering albedo of urban aerosols and fogs were inversely proportional to the wavelength.
