The Sounding of Hydrogen Sulfide Molecules by the Raman Light Scattering Lidar Installed on a Flying Platform

详细

The lidar equation is solved numerically for the Raman backscattering by hydrogen sulfide molecules in the atmosphere and water with concentrations about 10¹¹–10¹⁵ cm^–3 from a flying platform at heights up to 500 m in the synchronous photon counting mode. It is shown that, with this level of concentration of examined molecules at a depth down to 100 m, laser radiation wavelength of 532 nm, and height of the platform up to 500 m, the time of measuring this parameter does not exceed 34 min. The development of new lidar techniques provides additional opportunities for remote sounding of low concentrations of hydrogen sulfide molecules in the ocean water.
