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.
Journal ArticleDOI

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 generalised method for the extraction of chemically resolved mass spectra from aerodyne aerosol mass spectrometer data
James Allan,A. E. Delia,Hugh Coe,Keith Bower,M. Rami Alfarra,Jose L. Jimenez,Ann M. Middlebrook,Frank Drewnick,Timothy B. Onasch,Manjula R. Canagaratna,John T. Jayne,Douglas R. Worsnop +11 more
TL;DR: A generalised method for deconvolution of mass spectral data from the aerodyne aerosol mass spectrometer (AMS) is presented in this paper, which is designed to arithmetically separate the raw data into partial mass spectra for distinct chemical species.
Journal ArticleDOI
Quantitative sampling using an Aerodyne aerosol mass spectrometer 1. Techniques of data interpretation and error analysis
James Allan,Jose L. Jimenez,Jose L. Jimenez,Paul I. Williams,M. Rami Alfarra,Keith Bower,John T. Jayne,Hugh Coe,Douglas R. Worsnop +8 more
TL;DR: In this paper, the authors used the quadrupole mass spectrometer (AMS) during the mass spectrum (MS) mode of operation to estimate the chemical composition and size of volatile and semivolatile fine airborne particulate matter.
Journal ArticleDOI
Characterization of urban and rural organic particulate in the Lower Fraser Valley using two Aerodyne Aerosol Mass Spectrometers
M. Rami Alfarra,Hugh Coe,James Allan,Keith Bower,Hacene Boudries,Manjula R. Canagaratna,Jose L. Jimenez,John T. Jayne,Arthur Garforth,Shao-Meng Li,Douglas R. Worsnop +10 more
TL;DR: In this paper, the variability of the organic particulate composition and size distribution as a function of location and photochemical activity with a particular emphasis on the urban and rural areas was studied.
