Paper Abstract

The method of differential absorption with scattering (DAS) for atmosphere probing by means of NH3-CO2 laser system on the two wavelengths of infrared region far separated from each other is reviewed. The most perspective scheme of remote probing of atmosphere by such method is determined. The efficiency of NH3-CO2 lidar in region 9 - 13 μm is shown. There was found, that using of passive synchronization of longitudinal modes does not require corrections, taking into account the differences in the generation pulses shape of NH3 and CO2 lasers, if the analysis of a registered signal will be fulfilled on the front of a scattered radiation. The calculations of the probing sensitivity and remoteness on some components of atmosphere polluting, such as CCI4, NH3 and CFCl3 there carried out with lidar equation helping.
