The results of numerical solution of the lidar equation for the Raman scattering on the molecules of a gas mixture of hydrogen sulfide and methane in the 180° direction when probing the molecules of hydrogen sulfide and methane in the atmospheric boundary layer with concentrations in the range of 10¹⁰–10¹⁶ cm^–3 from a flying platform at altitudes of up to 500 m in the synchronous photon counting mode are presented. It is shown that concentrations of the studied hydrogen sulfide and methane molecules below the level of the maximum permissible concentration (MPC) for such a version of the Raman scattering lidar can be recorded within a measurement time of 10 s when probing at a laser radiation wavelength of 405 nm and a platform flight height in the range of up to 500 m.

从飞行平台对大气中的硫化氢和甲烷分子的混合物进行激光雷达探测

探测大气边界层中硫化氢和甲烷的分子的浓度范围为时，激光硫化物和甲烷的气体混合物分子在180°方向上的拉曼散射的激光雷达方程数值解的结果。 10 ¹⁰ –10 ¹⁶厘米^–3提出了在同步光子计数模式下从高达500 m的飞行平台上飞行的信号。结果表明，当在激光辐射波长下探测时，可以在10 s的测量时间内记录所研究的硫化氢和甲烷分子的浓度低于此类拉曼散射激光雷达的最大允许浓度（MPC）的水平。 405 nm的高度，平台飞行高度可达500 m。
