TL;DR: A unifying model framework describing the atmospheric evolution of OA that is constrained by high–time-resolution measurements of its composition, volatility, and oxidation state is presented, which can serve as a basis for improving parameterizations in regional and global models.

TL;DR: In this article, organic aerosol data acquired by the AMS in 37 field campaigns were deconvolved into hydrocarbon-like OA (HOA) and several types of oxygenated OA components.
Journal ArticleDOI
A New Time-of-Flight Aerosol Mass Spectrometer (TOF-AMS)—Instrument Description and First Field Deployment
Frank Drewnick,Silke S. Hings,Peter F. DeCarlo,John T. Jayne,Marc Gonin,Katrin Fuhrer,S. Weimer,Jose L. Jimenez,Kenneth L. Demerjian,Stephan Borrmann,Douglas R. Worsnop +10 more
TL;DR: In this article, the authors report the development and first field deployment of a new version of the AMS, which is capable of measuring non-refractory aerosol mass concentrations, chemically speciated mass distributions and single particle information.
Journal ArticleDOI
Chase Studies of Particulate Emissions from in-use New York City Vehicles
Manjula R. Canagaratna,John T. Jayne,David A. Ghertner,Scott C. Herndon,Q. Shi,Jose L. Jimenez,Philip J. Silva,Paul I. Williams,Thomas Lanni,Frank Drewnick,Kenneth L. Demerjian,Charles E. Kolb,Douglas R. Worsnop +12 more
TL;DR: In this article, the authors used an Aerodyne aerosol mass spectrometer (AMS) to provide size-resolved and chemically resolved characterization of the nonrefractory portion of the emitted PM; refractory materials such as elemental carbon were not measured in this study.
Journal ArticleDOI
Characterization of the sources and processes of organic and inorganic aerosols in New York city with a high-resolution time-of-flight aerosol mass apectrometer

TL;DR: In this paper, a high-resolution time-of-flight mass spectrometer was used to measure submicron aerosol particles (PM1) using a High-Resolution Time-offlight Aerosol Mass Spectrometer during the summer 2009 Field Intensive Study at Queens College in New York, NY Organic aerosol (OA) and sulfate are two dominant species, accounting for 54% and 24% of the total PM1 mass.
