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

TL;DR: A detailed discussion of the strengths and limitations of the AMS measurement approach is presented and how the measurements are used to characterize particle properties are reviewed to highlight the different applications of this instrument.
Journal ArticleDOI
Budget of organic carbon in a polluted atmosphere: Results from the New England Air Quality Study in 2002

TL;DR: In this article, an extensive set of volatile organic compounds (VOCs) and particulate organic matter (POM) was measured in polluted air during the New England Air Quality Study in 2002.
Journal ArticleDOI
Evaluation of Composition-Dependent Collection Efficiencies for the Aerodyne Aerosol Mass Spectrometer using Field Data
TL;DR: In this article, the authors evaluated the AMS collection efficiency using independent measurements of fine particle volume or particle-into-liquid sampler (PILS) ion chromatography measurements for three field campaigns with different dominant aerosol mixtures: acidic sulfate particles, ammonium nitrate, and biomass burning emissions.
