Abstract:

A numerical solution of the lidar equation was obtained for the Raman scattering of light by hydrogen-sulfide molecules in the 180° direction under daylight probing conditions to select the wavelength of laser radiation and lidar parameters as well as to determine the maximum power of Raman scattering or minimum possible time for the measurement of the concentration of hydrogen-sulfide molecules. For our Raman lidar, the optimal wavelength of laser radiation is 266 nm, which enables the detection of a concentration of 10¹³ cm⁻³ within a duration of the order of 100 s.

Keywords:

lidar equation, Raman scattering of light, hydrogen-sulfide molecules, atmosphere, wavelength of laser radiation, time for measurement
