Abstract

The paper discusses various aspects of statistical modeling of transspectral processes used in laser sensing of the meteorological parameters of the atmosphere. The need in invoking the rigorous apparatus of the Monte Carlo methods arises if meteorological lidars are operated under the conditions of the cloudy atmosphere, when the role of the multiply scattered component of a lidar signal becomes significant. The particular attention is paid to construction of algorithms for modeling of radiative transfer processes. The importance of correct choice of the model of elastic and inelastic molecular scattering is demonstrated. In particular, in simulation of photon scattering angles in the process of Markovian wandering, the form of the scattering phase function should be taken adequate to the conditions of Raman excitation. The results of methodic calculations are presented and compared with the data of other authors. Based on the results obtained, some features of formation of the multiple-scattering background in Raman sensing channels are established.
