Modified technique for processing multiangle lidar data measured in clear and moderately polluted atmospheres

Abstract

We present a modified technique for processing multiangle lidar data that is applicable for relatively clear atmospheres, where the utilization of the conventional Kano-Hamilton method meets significant issues. Our retrieval algorithm allows computing the two-way transmission and the corresponding extinction-coefficient profile in any slope direction searched during scanning. These parameters are obtained from the backscatter term of the Kano-Hamilton solution and the corresponding squarerange- corrected signal; the second component of the solution, related with the vertical optical depth, is completely excluded from consideration. The inversion technique was used to process experimental data obtained with the Missoula Fire Sciences Laboratory lidar. Simulated and real experimental data are presented that illustrate the essentials of the data-processing technique and possible variants of the extinction-coefficient profile retrieval.
