CCN activity and organic hygroscopicity of aerosols downwind of an urban region...
Thalman, Ryan M.; Sá, Suzane S. de; Palm, Brett B.; Barbosa, H. M. J.; Pöhlker, Mira L.; Alexander, Michael Lizabeth; Brito, Joel F.; Carbone, SamaraDuring the Observations and Modeling of the Green Ocean Amazon (GoAmazon2014/5) campaign, size-resolved cloud condensation nuclei (CCN) spectra were characterized at a research site (T3) 60 km downwind of the city of Manaus, Brazil, in central Amazonia for 1 year (12 March 2014 to 3 March 2015). Particle hygroscopicity (κCCN) and mixing state were derived from the size-resolved CCN spectra, and the hygroscopici...
Urban influence on the concentration and composition of submicron particulate m...
Sá, Suzane S. de; Palm, Brett B.; Campuzano-Jost, Pedro; Day, Douglas A.; Hu, Weiwei; Isaacman-VanWertz, Gabriel A.; Yee, Lindsay D.; Brito, Joel F.An understanding of how anthropogenic emissions affect the concentrations and composition of airborne particulate matter (PM) is fundamental to quantifying the influence of human activities on climate and air quality. The central Amazon Basin, especially around the city of Manaus, Brazil, has experienced rapid changes in the past decades due to ongoing urbanization. Herein, changes in the concentration and comp...
