Abstract

The paper presents the results of assessing pyrogenic emissions of carbon compounds in Russian forests for 2020 using remote monitoring methods. The area of forests damaged by fires was 6.5 mln ha, whereas the amount of carbon emissions was 36.5 MtC. Although the total area of damage is higher than the average annual values, the amount of pyrogenic carbon emissions is lower than the average annual ones. In absolute terms, the year corresponds to 2016. We registered an increase in annual carbon emissions from fires since the abnormal 2012. A preliminary analysis of the entire observation period for fires suggests that 2021 may be the next abnormal year after the years of 2003 and 2012 in terms of forest fires and direct pyrogenic carbon emissions into the atmosphere.

Highlights

The paper presents the results of assessing pyrogenic emissions of carbon compounds in Russian forests for 2020 using remote monitoring methods
Many current approaches use the results of the analysis of burned forested areas and data on the pre-fire stock volume of forest fuel load (FFL) biomass for modelling of pyrogenic carbon emissions (Kasischke, Bruhwiler, 2002; Isaev et al, 2002; Rinsland et al, 2007; Junpen et al, 2011; Dolman et al, 2012; Zamolodchikov et al, 2017)
The method developed at the CEPF RAS and modified by the authors in different years provides for the calculation of the stock volume of the main burn conductors of FFL before the fire (Sochilova et al, 2009)
