A method for simultaneous estimation of aerosol size distribution and refractive index from observation of the direct, diffuse, aureole radiance and polarization on the ground was proposed. In the method, a polarization computation based on the successive orders of scattering by separating the molecular and aerosol phase functions to the parallel and perpendicular polarization components in the first order scattering (single scattering) is introduced. Through a comparison between the proposed method and the Volume Spectral Analysis soft (Skyrad.pack) developed by Nakajima et al, it is found that the proposed method is superior to the Skyrad.pack method as aerosol optical depth is thin.
