Results of a closed numerical experiment on laser sensing of minor gas impurity concentrations in the tropospheric layer of the atmosphere based on new hybrid LIDAR-DOAS technique with a XeCl* excilamp used for a pulsed wideband radiation source are discussed. Quantitative estimates obtained using a new stochastic genetic search algorithm confirm that the suggested approach, expanding the possibilities of the classical Differential Optical Absorption Spectroscopy (DOAS) system to remote monitoring and localization of dangerous anthropogenic emissions of toxic gases up to the tropopause height, is promising. The necessity of estimating backscattered signals with high spectral resolution by solving the nonstationary radiative transfer equation calls for a significant modification of the statistical simulation algorithms. A combination of the Monte Carlo method with a genetic algorithm of solving inverse problems of reconstructing profiles of gaseous components in the troposphere enables exact quantitative prediction of the efficiency of new promising lidar systems of environmental monitoring to be provided.
