Abstract. The results of calculating the atmospheric transmission spectrum and modeling lidar signals in the informative range of greenhouse gases (CO2, H2O) sounding on horizontal tropospheric paths using the 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 CO2 and H2O. In this range, the level of lidar signals lies in the range of 10–6–10–10 W and exceeds the equivalent power photodetector noise. Based on the results of the calculations, the technical appearance of the developed two-channel infrared lidar system was determined.

Key words: lidar, atmosphere, greenhouse gases, infrared region.

Financing: The study was supported by the Russian Science Foundation grant No. 22-79-10203, https://rscf.ru/en/project/22-79-10203/
