Estimation of Direct Fire Emissions from Forests Burning in Siberia
Using a database on wildfires recorded by remote sensing for 1996–2020, we assessed the seasonal variation of direct carbon emissions from the burning in Siberian forests. We have implemented an approach that takes into account the combustion parameters and the changing intensity of the fire (in ter...

Using a database on wildfires recorded by remote sensing for 1996–2020, we assessed the seasonal variation of direct carbon emissions from the burning in Siberian forests.

For the last two decades, the range of direct carbon emissions from wildfires was 20–250 Тg С per year.
