Global secondary organic aerosol from isoprene oxidation

摘要: [1] Inclusion of isoprene as a source secondary organic aerosol (SOA) in global model increases the burden SOA from all sources by more than factor two. The substantially concentrations free troposphere, because isoprene, and, importantly, isoprene's oxidation products, have much greater at higher altitudes other biogenic precursors, highlighting importance semi-volatile organics for formation. These results are robust with respect to partitioning non-isoprene products and increased wet removal products. This additional enhances production parent hydrocarbons 17%, leads an overall distribution that differs enough previous predictions warrant reevaluation radiative effects carbon aerosol.
