Emissions of Trace Gases from Experimental Fires in Central Siberia, Russia
Abstract
Although the boreal forest in Siberia, Russia contains approximately one-fourth of the world's terrestrial biomass, emissions data from biomass burning in Siberia is scarce. Five experimental fires of varying intensity were conducted in Central Siberia in 2000 and 2001. The vegetation type is Scotch pine forest with a lichen, feather moss, and vaccinium understory. Smoke samples were taken from the ground and by helicopter, as part of the FIREBEAR project. We analyzed concentrations of CO2, CO, H2, CH4, C2H4, C2H6, C3H6 and C3H8 in stainless steel canisters that were collected by helicopter. Emitted hydrogen concentrations were highly linearly correlated with CO concentrations for the 3 fires sampled in 2001. Emitted CO2 and CH4 also showed a high degree of correlation with CO emissions for most fires. Emissions were sampled at ground level into glass bottles. CO2, CH4, ethylene, and propane were linearly correlated with CO. No significant differences were found in the emission ratios of different trace gases to CO for different fire intensities or vegetation. We will also present emission factors of CO2, CO, CH4, ethylene, ethane, propylene, and propane for different fire intensities in Central Siberia.
