Abstract
The subject of this paper is an estimation of possibility of gas analysis by differential absorption lidars (DIAL) based on gas lasers of the middle IR spectrum range. The potential of lidar systems based on CO2 laser with radiation frequency converter for ground and onboard sensing of atmospheric water vapor and carbonic oxide concentration profiles is analyzed. Possibilities of NO and NO2 emission detection in ground atmospheric layers using converted frequencies of CO and CO2 laser radiation in onboard DIAL are discussed. Absorption lines for methane and ammonia sensing by lidar system based on tunable TEA CO2 laser with frequency converter has chosen. The results of an estimation of methane leakage detection from pipelines by onboard lidar are submitted. Applicability of the DF laser in onboard DIAL for control of atmospheric gases is reported.
