TL;DR: Several of the organosulfates of isoprene and of the monoterpenes characterized in this study are ambient tracer compounds for the occurrence of biogenic SOA formation under acidic conditions and reveal a viable mechanism for the formation of previously identified nitrooxy organosolfates found in ambient nighttime aerosol samples.
Journal ArticleDOI

TL;DR: Sulfate esters are found to account for a larger fraction of the SOA mass when the acidity of seed aerosol is increased, a result consistent with aerosol acidity increasing SOA formation.
Journal ArticleDOI
Estimates of the contributions of biogenic and anthropogenic hydrocarbons to secondary organic aerosol at a southeastern US location

TL;DR: In this paper, an organic tracer-based method containing laboratory and field study components was used to estimate the secondary organic aerosol (SOA) contributions of biogenic and anthropogenic hydrocarbons to ambient organic carbon (OC) concentrations in PM2.5 during 2003 in Research Triangle Park, NC.

TL;DR: Aerosol mass concentrations for the 2-methyltetrols, as well as the newly identified sulfate esters, both of which serve as tracers for isoprene SOA in ambient aerosols, increased significantly with enhanced aerosol acidity.
Journal ArticleDOI
Formation of 2-methyl tetrols and 2-methylglyceric acid in secondary organic aerosol from laboratory irradiated isoprene/NOX/SO2/air mixtures and their detection in ambient PM2.5 samples collected in the eastern United States

TL;DR: In this article, an isoprene/NO X /air mixture was irradiated in a flow reactor smog chamber in both the absence and presence of SO 2 to measure the SOA yield and to establish whether the two 2-methyl tetrols and 2methyl glyceric acid are present in isoprane SOA and could serve as SOA indicator compounds.
