Ten years later, data gathered in Brazil have proven highly influential across atmospheric science: GoAmazon
However, the Amazon is not totally isolated. More than just forest, it contains numerous human settlements, such as the city of Manaus. With a population just over 2 million, Manaus is the largest city in the Amazon region. It acts as the sole source of human-driven emissions for a swath of the Amazon, generating a pollution plume that can be monitored.
While GoAmazon produced many types of data, many of the significant scientific conclusions from the campaign center on aerosols—their formation, behavior, and interactions with other atmospheric processes., an atmospheric chemist at PNNL. “ARM’s GoAmazon field site was perfectly positioned to allow us to observe both natural aerosol processes and the influence of human emissions on aerosols. We could study not only how the particles form, but also how they grow.
Beyond understanding the natural processes of forests, the location of the GoAmazon study site directly in the path of pollution from Manaus provided an opportunity to examine how human activities affect natural atmospheric behavior.the pollution plume interacts with the organic molecules released from the trees. The small background particles grow much larger than during periods when the plume is absent.
The massive aerosol increase occurs from interactions between the natural organic molecules and nitrogen oxides. The nitrogen oxides can react with the natural emissions, changing the chemical makeup of molecules in the atmosphere and affecting what types of further chemical reactions can occur. “Results from GoAmazon fundamentally changed how we understand human influences on aerosol and climate,” says Jiwen Fan, who performed this work at PNNL before becoming the deputy division director for environmental science at Argonne National Laboratory. “Previously, conventional thought was that ultrafine particles, like what we observed in GoAmazon, were too small to affect cloud formation.
