In this paper we present a method for using multiple-view-angle imagery to retieve atmospheric aerosol optical properties. Once determined, these optical properties would be used in a surface reflectance retrieval algorithm designed to correct for atmospheric effects. The method makes use of the presence of spatial contrasts within the imagery, and compares the Fourier transforms of the multi-angle images at zero and nonzero spatial frequencies. An initial guess for the aerosol properties is made and corrections for atmospheric effects at zero and nonzero frequenceis are performed. The results are then analyzed to establishe whether the initial guess was correct. Other than the need to define a relationship between the angular variation of teh Fourier transform fo the intrinsic surface angular reflectance at the zero and nonzero frequencies, the method asumes no a priori knowledge about the aerosols or surface characteristics. Sensitivities to various parameters are discussed.
