“…For this reason, the problem of monitoring greenhouse gas concentrations using methods and means of remote sensing is relevant today. Among the methods of gas analysis, one can distinguish the method of differential absorption lidar technique (DIAL) [1][2][3][4] and differential optical absorption spectroscopy (DOAS) [5]. The aim of this work is to develop an IR lidar system for the simultaneous reconstruction of spatially resolved profiles and concentrations of the studied greenhouse gases (CO 2 , H 2 O) averaged along the horizontal sounding path using the DIAL and DOAS registration channels.…”

The results of the calculation of atmospheric transmission spectra and modeling of lidar signals in the informative range of greenhouse gases sounding (CO 2 , H 2 O) on horizontal tropospheric paths by using a two-channel infrared lidar system under development are presented. It is shown that the spectral range of operation of the lidar system 4878-4894 cm -1 (2043-2050 nm) is preferable for simultaneous probing of CO 2 and H 2 O, in which the level of lidar signals is in the range of 10 -6 -10 -10 W and exceeds the equivalent noise power photodetector. Several configurations of the lidar system with the generation of nanosecond radiation pulses in the selected informative range of sounding the trace gases under study are proposed.

“…Therefore, monitoring of atmospheric methane is a topical problem. An important scientific task is the detection of the methane concentrations in the atmosphere with the use of spectroscopic techniques and sounding instruments [1][2][3][4]. This is to advance fundamental knowledge about the impact of anthropogenic (coal mining, landfills, biomass combustion, oil and gas industry, rice fields, ruminant animals) and natural (bogs) factors of the global increase in the total content of greenhouse gases and their contribution to the climate change.…”

Methane (CH 4 ) is a greenhouse gas which directly influences climate changes on the planet. One of the sources of methane emissions in the atmosphere during human agricultural activities is the decay of animal manure and organic components of agricultural effluents. Therefore, remote control and measurement of the concentrations of agricultural products (mainly methane), which are essentially an anthropogenic factor of the impact on the atmosphere, is important. Here, we consider a possibility of creating a mobile laser absorption complex for methane monitoring at cites with agricultural effluents.

“…Laser detection and measurement of the concentrations of atmospheric gases (greenhouse gases in particular) in the IR spectral region is based on the principle of laser absorption spectroscopy (LAS). Among LAS gas analysis methods, the differential absorption technique (differential absorption lidar (DIAL) and integral-path differential absorption (IPDA)) [1][2][3][4][5][6][7] and diode laser absorption spectroscopy (DLAS) [8][9][10][11][12] should be noted.…”
