The problem of determination of optical and microphysical parameters of aerosol in turbid atmosphere from data of multiwavelength lidar sensing including Raman signals from atmospheric nitrogen is discussed. Solution of lidar equations along with retrieval of aerosol parameters is performed by iteration scheme using integral relations obtained by means of Fernald transform. Algorithm of retrieval of optical parameters in the iteration scheme is based on a priori information on the aerosol particle size-distribution function.
