Abstract

Lidar systems for the pollution molecules concentration remote measurements in the atmosphere can become a basis for the atmospheric air quality controlling systems and the emergency pollution emissions prediction in the atmosphere under the industrial enterprises. The Raman lidar potential possibilities estimation with the diode lasers for the hydrocarbons molecules sensing in atmosphere for such molecules concentration level detection in atmosphere over industrial region and above is the present paper goal. The Raman lidar equation computer simulation results show the possibility of the optimal laser radiation wavelength choosing for the hydrocarbon molecules sensing in atmosphere in the photon-counting regime and these molecules concentration level exceeding over the given level in the distance range from 10 m up to 1 km. The 405 nm diode laser radiation was the best result wavelength with the minimal detection time value of 180 ms for the pentane molecule at the ranging distance of 1 km in the photon-counting Raman lidar regime.
