When forests burn those fires produce a lot of smoke. And that smoke usually contains soot, also called “black carbon”. Black carbon particles are aerosols that absorb radiation and as such can warm the Earth’s atmosphere and climate. But we still have much to learn about aerosols, their properties, and distribution in the atmosphere. One of those things is the question of how black carbon emitted from biomass burning in Africa (i.e. forests, grasslands, savannas etc.) is transported across the Atlantic and into the Amazon basin, and what role it plays there. Bruna Holanda and her co-authors tackled this by combining data from the northeastern Amazon collected with the HALO research aircraft during the ACRIDICON-CHUVA campaign in September 2014, with long-term data from ATTO.
Aerosols play an important role in various atmospheric processes, and in particular in cloud formation. Therefore it is important to know how they are produced.
