Potential of Pulsed Excilamps for Remote Sounding of Polluted Atmosphere

摘要

The results are discussed of a closed numerical experiment on lidar sounding of the concentration of small gas impurities in the tropospheric layer of the atmosphere based on a new LIDAR-DOAS hybrid technology that uses a XeCl~(*) excilamp as a source of pulsed broadband radiation. Quantitative estimates confirm the promise of the approach, which expands the potential of the classical scheme of differential optical absorption spectroscopy (DOAS) with respect to the remote monitoring and localization of hazardous anthropogenic emissions of toxic gases. Combining the Monte Carlo method with the genetic algorithm for solving the inverse problem of reconstructing the profiles of sought gas constituents of the troposphere makes it possible to strictly quantitatively predict the efficiency of new promising lidar systems for monitoring the environment.
