Abstract

The integral solutions of the lidar equation (Klett, 1981) commonly in use suffer from the fact of a priori assumed boundary values and relationship between backscattering and extinction coefficients. The integral method of the multiposition lidar sounding of the atmospheric aerosols was developed to exclude traditional systematic errors. The method is based on sounding of investigated atmospheric volume by lidar system transmitting pulses from different points in space and receiving the backscattering signals. It gives possibility to find a posteriori relationship between measured coefficients and the unknown boundary values using Bernulli solutions of lidar equation for beampaths segments forming polygons with common points. The effectiveness of the method is analysed for the ruby lidar system (Yegorov, 1996).
