The funding of collaborative research with the scientific campaign GOAmazon aims at promoting and strengthening cooperation in research on Amazonian tropical ecosystems, by researchers from the DoE and the State of São Paulo, and collaborations between researchers from DOE, the State of São Paulo and the State Amazon, Brazil. For that purpose, it gathers three programs of the U.S. Department of Energy (DoE) - Atmospheric Systems Research (ASR), Regional and Global Climate Modeling (RGCM) and Terrestrial Ecosystem Science (TES) -; of the São Paulo Research Foundation (FAPESP) Program Research on Global Climate Change (PFPMCG), and of the Amazonas Research Foundation (FAPEAM).
This proposed research aims to study the lifecycle of secondary aerosols in pristine and polluted conditions in the atmospheric boundary layer (ABL) of Amazonia. The investigation spans the biological and physical conditions influencing emissions and reactions of precursors (biogenic and anthropogenic volatile organic compounds, VOCs), formation, transport of aerosols out of the ABL and t…
Manaus, a city of nearly two rnillion people, represents an isolated urban area having a distinct urban pollution plume within the otherwise pristine Amazon Basin. The plume has high concentrations of oxides ofnitrogen and sulfur, carbon monoxide, particle concentrations, and soot, among other pollutants. Critically, the distinct plume in the setting ofthe surrounding tropical rain forest…
The Amazon currently plays a criticaI role in the terrestrial climate system, in terms of, e.g., regulating carbon stocks and supporting high biodiversity and endemism. Over the last decade, Amazonian forests have begun experiencing more frequent dry periods, including two extreme drought episodes in 2005 and 2010. However, the future of the Amazon as projected by current generation clima…
