Оценка погрешности лидарных измерений концентрации сероводорода в атмосфере

Abstract

The measurement error estimation of the hydrogen sulfide molecules concentration in the range of 10¹⁰-10¹⁴ cm^-3 in the atmosphere by Raman lidar and the differential absorption and scattering lidar at the range distances up to 2 km has been fulfilled. It was shown that the Raman lidar can during measurement time of 100 s record such a concentration of the studied molecules in the atmosphere with the relative error no more than 20 % for all range of distances and the differential absorption and scattering lidar at the 3,83 µm wavelength measurement relative error lies in the range of 20-26 %.
