Regularizing Algorithm and Processing Software for Raman Lidar-Sensing Data

An algorithm and software suite for computing profiles of atmospheric aerosol optical parameters using Raman lidar-sensing data were presented. A two-step procedure for statistical regularization of the solution was carried out within the algorithm. Initially, the lidar ratio in the aerosol layer was considered to be constant and its value was calculated. Then, the profile of the aerosol lidar ratio was corrected with additional restrictions on the smoothness of the solution and the deviation from the mean. A program module executing the proposed algorithm was described and represented a part of an integrated LIRIC software suite for processing complex lidar and radiometric data from atmospheric aerosol sensing.
