Beyond megacities: tracking air pollution from urban areas and biomass burning in Brazil

Abstract Most of the world’s population lives in rural areas or small to medium-sized cities (totalling 68% of the world population), all of which are impacted by distant air pollution sources. In Brazil, primary pollutant emissions have decreased in urban centres because of government actions, whil...
