Reconstruction of microstructure and aerosol optical characteristics from the data of lidar multifrequency sensing: methods and experimental results

摘要

Abstract: It is known that the use of lidar systems for investigation of the atmospheric aerosol makes it possible to obtain the optical characteristics and, with some definite assumptions, the scattering particles concentration. To have information about the aerosol microstructure, and especially about its space-time variations, it is necessary to enlarge the measuring information volume. With the monostatic pulse scheme of sounding, such an enlargement can be realized in the lidar using several lasers with different wavelengths. These optical systems are complicated technically and need automatization of the measuring complex. In order for the multifrequency laser sounding to be an effective method for remote measurements of the aerosol characteristics, it is necessary to develop mathematical methods of the algorithms for solution of the corresponding inverse problems taking into account their mathematical incorrectness. The results of these investigations, and their practical application, are described in detail in the papers. !7
