Assessing the impact of anthropogenic pollution on isoprene-derived secondary organic aerosol formation in PM2.5 collected from the Birmingham, Alabama, ground site during the 2013 Southern Oxidant and Aerosol Study

Autor: W. Rattanavaraha, K. Chu, S. H. Budisulistiorini, M. Riva, Y.-H. Lin, E. S. Edgerton, K. Baumann, S. L. Shaw, H. Guo, L. King, R. J. Weber, M. E. Neff, E. A. Stone, J. H. Offenberg, Z. Zhang, A. Gold, J. D. Surratt

Publikováno v: Atmospheric Chemistry and Physics, Vol 16, Pp 4897-4914 (2016)

In the southeastern US, substantial emissions of isoprene from deciduous trees undergo atmospheric oxidation to form secondary organic aerosol (SOA) that contributes to fine particulate matter (PM2.5). Laboratory studies have revealed that anthrop
