Monitoring hydrogen sulfide molecules in the atmospheric boundary layer by differential absorption and scattering lidar from space

The results of the numerical solution of the lidar equation for differential absorption and scattering are presented for probing hydrogen sulfide molecules in the atmosphere with a concentration level of 1011  cm−3 from a space platform at altitudes from hundreds of kilometers to geostationary orbit. It is shown that the measurement time for the level of such a concentration of the investigated hydrogen sulfide molecules at a laser wavelength of 3.83 μm and an altitude of 100 to 36,000 km lies in the range of 0.8 μs–10.5 s for a differential absorption and scattering lidar. Therefore, it is possible to measure the concentrations of the investigated hydrogen sulfide molecules at a level of 1011  cm−3 with such a lidar from a space platform.
