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
Field-Deployable, High-Resolution, Time-of-Flight Aerosol Mass Spectrometer

TL;DR: The development of a new high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS) is reported, which allows the direct separation of most ions from inorganic and organic species at the same nominal m/z, and the quantification of several types of organic fragments.
Journal ArticleDOI

TL;DR: A recently developed method to rapidly quantify the elemental composition of bulk organic aerosols (OA) using a high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS) is improved and applied to ambient measurements.
Journal ArticleDOI
