Several satellite products are currently used for thelatter, among them, the distributions of active fires (AF) and of burnt areas (BA). Though progress has beenachieved by individual groups using these new satellite-based products, there still are substantial differencesin the results obtained and methods used. In this context, BBSO1 and BBSO2 workshops were jointlyorganized in Toulouse, France in 2005 and 2009 between users and producers of burnt biomass estimateswithin the ACCENT network and the GEIA/AIMES/IGBP project, with an intercomparison exercise focusedon CO emission estimates for 2003. In this talk, results for this exercise will be shown, dealing with theorigin of differences between emission estimates by regions, land cover types... Three datasets using abottom-up approach (Seiler and Crutzen 1980) and satellite-based biomass burned estimates (VGT, ASTRand MODIS) were compared and one dataset derived from a top-down approach from satellite (NASA-MOPITT) concentration data. This work will also be compared to FRP-based emission inventory (Kaiser etal., 2010) and GFED inventories. Results confirm the high variability of spatial and temporal patterns of COemissions, with the greatest discrepancies occurring in the forest classes of the Northern Hemisphere, whileAfrica shows the best agreement among inventories, both in terms of total annual amounts and seasonality.Finally these results, discussed in the BBSO2 workshop allowed to yield regional recommendations for usersin terms of satellite product uses and also to focus on the need of international works, both experimental andalgorithmic.P-Sources.11 ID:4458 15:35Results from a large, multi-platform study of trace gas and particle emissions from biomass burningIan Burling 1 , Robert Yokelson 1 , Sheryl Akagi 1 , Shawn Urbanski 2 , Carsten Warneke 3 , Patrick Veres 3 ,James Roberts 4 , Jessica Gilman 3 , William Kuster 4 , David Griffith 5 , Timothy Johnson 6 , David Weise 71 Department of Chemistry, University of Montana2 USDA Forest Service, Rocky Mountain Research Station3 CIRES at the University of Colorado; NOAA ESRL4 NOAA ESRL5 Department of Chemistry, University of Wollongong6 Pacific Northwest National Laboratory7 USDA Forest Service, Pacific Southwest Research StationContact: ian.burling@umontana.eduWe report preliminary results from a large, multicomponent study focused on North American biomassburning that measured both initial emissions and post-emission processing.
