Abstract

Based both on substantianed criteria for the selection of absorption lines and on a proposed algorithm for the calculation of the atmospheric transmission, a technique to search for informative wavelengths is developed for lidar gas analysis by a differential absorption lidar (DIAL). This technique can be applied to any spectral region upon condition that data on a laser source are supplied. Results of the search for the informative probe light wavelengths in the mid-IR spectral region are presented. A possibility to use an overtone CO-laser for lidar sensing the trace atmospheric constituents has been examined. The calculation confirm that the application of the overtone CO-laser is promising for remote gas analysis of the atmosphere.
