Abstract

In the report, we present and summarize the results of lidar measurements of stratospheric aerosol layer at the Siberian Lidar Station (Tomsk: 56.5°N; 85.0°E) in 2017. Measurement technique with the help of multichannel stationary lidar complex at Institute of Atmospheric Optics, Siberian Branch, Russian Academy of Sciences, Tomsk, is described. The measurements showed that in August – October there were aerosol layers in the altitude range from 14 to 19 km, with R(H) value at maximum having been from 1.3 to 5.8. The trajectory analysis of air mass transport in the atmosphere on the basis of the NOAA HYSPLIT models allowed us to determine that the observed aerosol layers could possibly be due to atmospheric transport of forest fire products from the region of lake Athabasca (Saskatchewan and Alberta provinces, Canada) to the atmosphere.
