Daily, seasonal and annual measurements of methane background variations were carried out in the northeast Moscow Region, both by active remote lidar operating at a wavelength ~ 1650 nm with powerful radiation source based on Raman amplifier, passive method, using solar as broadband light source. Observations urbanized areas near city, an environmentally friendly area low economic level activity. Over 4 years observations, concentration increased from 2.0 ppm to 2.24 ppm, 1.75 1.95 ppm. A...
A method for passive measurements of water vapor concentration in the atmosphere presence solar radiation has been proposed and tested. The location is northeast Moscow region. When processing results carried out on a single absorption line, coincidence experimental data obtained from direct meteorological with an error no more than ~7.5 % was revealed. It also found that line region 1653 nm, interfering factor nearby methane which introduces systematic measurement results, turn to be...
Using a prototype of remote lidar created in the laboratory for measuring methane concentration, study distribution along route ~ 2.25 km long was carried out order to localize gas emissions and control leaks unfavorable areas. The prototype, operating at wavelength 1653 nm, included powerful Raman amplifier made it possible measure distance reflection point with an accuracy no worse than 50 meters. scanned track, starting from short distances ending measurements entire measured track. near...
