Molecular composition of organic aerosols in central Amazonia: An ultra-high-re...
Kourtchev, Ivan N.; Godoi, Ricardo Henrique Moreton; Connors, Sarah; Levine, James G.; Archibald, Alexander Thomas; Godoi, Ana Flávia LocateliThe Amazon Basin plays key role in atmospheric chemistry, biodiversity and climate change. In this study we applied nanoelectrospray (nanoESI) ultra-high-resolution mass spectrometry (UHRMS) for the analysis of the organic fraction of PM2.5 aerosol samples collected during dry and wet seasons at a site in central Amazonia receiving background air masses, biomass burning and urban pollution. Comprehensive mass s...
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...
