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
Plan on Climate Change annual target for Amazonia C emission
reductions from deforestation.",
