Satellite Monitoring of Wildfires and Emissions into the Atmosphere of Combustion Products in Russia: Relation to Atmospheric Blockings

Using satellite and reanalysis data, estimates of the significant relationship between the wildfire areas and associated pyrogenic emissions of combustion products with atmospheric blocking events in Russia for the period from 2001 to 2019 were found. It has been established that the contribution to the variance of interannual changes of the wildfire areas and emissions of combustion products into the atmosphere associated with atmospheric blocking can reach and even exceed 40%. The tendency toward an increase in the density of emissions of combustion products into the atmosphere, including carbon dioxide and carbon monoxide, as well as fine aerosol, against the background of a general decrease in the areas of natural fires in the first 20 years of the 21st century, is revealed. At the same time, a decrease in the ratio of pyrogenic emissions of carbon monoxide and fine aerosol was found.
