A THEORETICAL STUDY OF MULTI-WAVELENGTH LIDAR EXPLORATION OF OPTICAL PROPERTIES OF ATMOSPHERIC AEROSOLS
摘    要:Feasibility is investigated of multi-wavelength lidar exploration of size distribution patterns (SDP) and -complex refractive indices (CRI) of aerosols in different layers of a stratified atmosphere, and an improved observational scheme is worked out for the optical parameters (extinction coefficients, angular scattering coefficients and their ratios) of the substance in layers homogeneous horizontally in optical depth obtained by a bi-static lidar system. Variations are examined of these parameters versus CRI (whose real part is 1.33-1.63 and imaginary 0.00-0.1) and working wavelengths (0.3472, 0.53, 0.6943 and 1.06 μm) in such SDP as Junge-3, 4 and 5. The Deirmendjian Haze M and L. A method is thereupon developed for retrieval of aerosols' SDP and CRI from these parameters and tested by suitable numerical experiments.
