TL;DR: In this article, the authors focus on the identification of the main organic aerosol sources and define a standardized methodology to perform source apportionment using positive matrix factorization (PMF) with the multilinear engine (ME-2) on Aerodyne aerosol mass spectrometer (AMS) data.

TL;DR: In this article, particle phase measurements performed at a suburban site in the Netherlands showed that organic nitrates contribute substantially to particulate nitrate and organic mass, implying a substantial potential of PM reduction by NOx emission control.
Journal ArticleDOI
Global transformation and fate of SOA: Implications of low-volatility SOA and gas-phase fragmentation reactions
Manish Shrivastava,Richard C. Easter,Xiaohong Liu,Alla Zelenyuk,Balwinder Singh,Kai Zhang,Po-Lun Ma,Duli Chand,Steven J. Ghan,Jose L. Jimenez,Qi Zhang,Jerome D. Fast,Philip J. Rasch,Petri Tiitta,Petri Tiitta +14 more
TL;DR: In this paper, the authors have implemented three new detailed SOA treatments within the Community Atmosphere Model version 5 (CAM5) that allow them to compare the semivolatile versus nonvolatile SOA treatment (based on some of the latest experimental findings) and investigate the effects of gas phase fragmentation reactions.
