Short summary
Wildfires in the Amazon worsen air pollution and threaten public health, yet the role of droughts in amplifying these effects is poorly understood. Using satellite data and atmospheric modeling, we assessed how droughts intensified fire emissions and pollution in the Brazilian Amazon from 2010–2015. During drought years, fires contributed up to 76 % of harmful particles and raised premature deaths by up to 24 %. These results stress the need for fire management that accounts for drought risks.
