Estimating of fire emissions in Boreal Siberia by satellite data sets

1 Introduction Boreal forest represents around 37% of the total terrestrial carbon pool,and the region is extremely important with regard to the Earths carbon cycle. About two thirds of earths closed boreal forest lies in Russian Federation,and this Russian forest represents around 25% of global terrestrial biomass. Conard et al.,2002; Myneni,et al.,2001 Biomass burning can produce large amounts of trace gases and mixtures of aerosol particles,which can be transferred across regions,or even globally. In our study,we used higher-reliable satellite data set for deriving burned area, estimated the combustion factor both temporally and spatially,and illustrated the impact of fire emissions on regional air quality. In this paper,we estimated fire emissions of CO,CO2,CH4, nonmethane hydrocarbons (NMHC),and black carbon (BC) in Boreal Siberia (including Siberia and the Russian Far East) from 2000 to 2008,based on several satellite data sets. And also,we calculated monthly emissions of BC and satellite-based aerosol optical depth (AOD) in the sub-region of Baikal (51N-56N,111E-116E) from 2002 to 2008,in order to exanimate impacts of fire emissions on air quality.
