Spacetime Distributions of Wildfire Areas and Emissions of Carbon-Containing Gases and Aerosols in Northern Eurasia according to Satellite-Monitoring Data

Abstract

Based on online wildfire satellite-monitoring data, distributions of burned-out areas, as well as emission volumes of carbon-containing gases (СО and СО2) and fine aerosols (РМ2.5), for different regions and months in 2005–2016 (across the territory of Russia) and in 2010–2016 (northern Eurasia) are analyzed. Distinctive features of the seasonal behavior of wildfires and emission volumes of carbon-containing gases and fine aerosols for different regions of northern Eurasia are determined. It is shown that between 2005 and 2016 the annual area of territories burned out during wildfires in Russia decreased by almost a factor of 2.6 owing to early detection and suppression of fire sources. It is determined that in 2014–2016 the relative size of burned-out areas in Ukraine increased 6–9-fold and volumes of СО, СО2, and РМ2.5 emissions by more than a factor of 6.5–7.5 times when compared to earlier years and these characteristics for other European countries.
