How to access global and regional burnt biomass from satellite observations to derive gases and particle emission inventories?
Calculating biomass burning emissions requires a knowledge of appropriate emission factors together with spatial and temporal distributions of burnt biomass. Several satellite products are currently used for the latter, among them, the distributions of active fires (AF) and of burnt areas (BA). Though progress has been achieved by individual groups using these new satellite-based products, there still are substantial differences in the results obtained and methods used. In this context, BBSO1 and BBSO2 workshops were jointly organized in Toulouse, France in 2005 and 2009 between users and producers of burnt biomass estimates within the ACCENT network and the GEIA/AIMES/IGBP project, with an intercomparison exercise focused on CO emission estimates for 2003. In this talk, results for this exercise will be shown, dealing with the origin of differences between emission estimates by regions, land cover types… Three datasets using a bottom-up approach (Seiler and Crutzen 1980) and satelli
