Description
Summary:The frequency of forest fires has recently increased. Combustion aerosol can enter the stratosphere, which can have noticeable consequences for the climate. In this work, we examine the transport of combustion aerosol into the stratosphere in summer 2019, when numerous wildfires occurred in Siberia, Canada, and Alaska. According to lidar observations at the stratospheric lidar station of the V.E. Zuev Institute of Atmospheric Optics, Siberian Branch, Russian Academy of Sciences, in Tomsk in August 2019, layers of aerosol scattering were pronounced in the lower stratosphere. The analysis of back air mass trajectories calculated on the basis of satellite radiometric information about fires in the Northern Hemisphere and CALIPSO lidar data allows a conclusion that the aerosol layers observed result from transfer of the combustion products of Siberian wildfires into the stratosphere.
