Abstract
In the report, we analyze the data of lidar measurements of optical characteristics of aerosol in the stratosphere over Tomsk; the analysis revealed the periods of elevated aerosol content after a series of explosive eruptions of volcanoes of the Pacific “Ring of Fire” and Iceland in 2006-2011. For these relatively weak eruptions (which injected to the stratosphere no more than 2 Mt of sulfur dioxide, serving the source for the sulfur acid aerosol formation), the periods of elevated aerosol content had been from a few months to half-year. Since 2012, a background state of aerosol loading had been established in the stratosphere over Tomsk. The regional empirical model of background stratospheric aerosol, developed by us for 2000-2008, was corrected to include data of measurements from 2012 to 2016.
