Epoxide as a precursor to secondary organic aerosol formation from isoprene photooxidation in the presence of nitrogen oxides

TL;DR: Evidence is presented that in the presence of high levels of nitrogen oxides typical of urban atmospheres, 2-methyloxirane-2-carboxylic acid (methacrylic acid epoxide, MAE) is a precursor to known isoprene-derived SOA tracers, and ultimately to SOA, and it is proposed that MAE arises from decomposition of the OH adduct of methacryloyl peroxide (MPAN).
Journal ArticleDOI

Characterization of a real-time tracer for isoprene epoxydiols-derived secondary organic aerosol (IEPOX-SOA) from aerosol mass spectrometer measurements

TL;DR: In this article, the authors applied positive matrix factorization (PMF) to aerosol mass spectrometer (AMS) measurements to identify secondary organic aerosol (SOA) formed from isoprene epoxydiols (IEPOX).
Journal ArticleDOI

Real-time continuous characterization of secondary organic aerosol derived from isoprene epoxydiols in downtown Atlanta, Georgia, using the aerodyne aerosol chemical speciation monitor

TL;DR: Analysis of organic mass spectra measured by the ACSM suggest IEPOX as the source of this additional OOA factor, which has some correlation with aerosol acidity and sulfate mass loading, consistent with prior work showing that these two parameters promote heterogeneous chemistry of IEPOx to form SOA.
