Urban pollution greatly enhances formation of natural aerosols over the Amazon ...
Shrivastava, Manish K.; Andreae, Meinrat O.; Artaxo, Paulo; Barbosa, H. M. J.; Berg, Larry K.; Brito, Joel F.; Ching, Joseph; Easter, Richard C.One of the least understood aspects in atmospheric chemistry is how urban emissions influence the formation of natural organic aerosols, which affect Earth’s energy budget. The Amazon rainforest, during its wet season, is one of the few remaining places on Earth where atmospheric chemistry transitions between preindustrial and urban-influenced conditions. Here, we integrate insights from several laboratory meas...
Observations of sesquiterpenes and their oxidation products in central Amazonia...
Yee, Lindsay D.; Isaacman-VanWertz, Gabriel A.; Wernis, Rebecca A.; Meng, Meng; Rivera, Ventura; Kreisberg, Nathan M.; Hering, Susanne V.<p>Biogenic volatile organic compounds (BVOCs) from the Amazon forest region represent the largest source of organic carbon emissions to the atmosphere globally. These BVOC emissions dominantly consist of volatile and intermediate-volatility terpenoid compounds that undergo chemical transformations in the atmosphere to form oxygenated condensable gases and secondary organic aerosol (SOA). We collected quartz fi...
