             abstract = "In less than 15 years, the Amazon region experienced three major 
                         droughts. Links between droughts and fires have been demonstrated 
                         for the 1997/1998, 2005, and 2010 droughts. In 2010, emissions of 
                         510  120 Tg C were associated to fire alone in Amazonia. Existing 
                         approaches have, however, not yet disentangled the proportional 
                         contribution of multiple land cover sources to this total. We 
                         develop a novel integration of multisensor and multitemporal 
                         satellite-derived data on land cover, active fires, and burned 
                         area and an empirical model of fire-induced biomass loss to 
                         quantify the extent of burned areas and resulting biomass loss for 
                         multiple land covers in Mato Grosso (MT) state, southern Amazonia 
                         - the 2010 drought most impacted region. We show that 10.77% 
                         (96,855 km2) of MT burned. We estimated a gross carbon emission of 
                         56.21  22.5 Tg C from direct combustion of biomass, with an 
                         additional 29.4  10 Tg C committed to be emitted in the following 
                         years due to dead wood decay. It is estimated that old-growth 
                         forest fires in the whole Brazilian Legal Amazon (BLA) have 
                         contributed to 14.81 Tg of C (11.75 Tg C to 17.87 Tg C) emissions 
                         to the atmosphere during the 2010 fire season, with an affected 
                         area of 27,555 km2. Total C loss from the 2010 fires in MT state 
                         and old-growth forest fires in the BLA represent, respectively, 
                         77% (47% to 107%) and 86% (68.2% to 103%) of Brazil's National
