Estimation of the Error of Lidar Measurements of the Concentration of Hydrogen Sulfide in the Atmosphere

Аннотация

The error of measurement of hydrogen sulfide concentration ranging from 10¹⁰–10¹⁴ cm^–3 in the atmosphere by Raman lidar as well as differential absorption and scattering lidar at distances up to 2 km was estimated. It was shown that Raman lidar over measurement time of 100 sec can record such concentration of the studied molecules in atmosphere with a relative error of no more than 20% for the entire range of distances, and for differential absorption and scattering lidar at the wavelength of 3.83 μm the relative measurement error lies in the range of 20–26%.
