TL;DR: In this paper, the authors identify specific compounds that are likely to contribute to the water-soluble fraction by juxtaposing observations regarding the extraction characteristics and the molecular composition of atmospheric particulate organics with compound-specific solubility and condensibility for a wide variety of organics.

TL;DR: A review of the current state of organic aerosol sampling, analysis, and simulation, examines the limitations of current technology, and presents prospects for the future is provided in this article, where the emphasis is on distilling findings from recent atmospheric, smog chamber, and theoretical studies to provide a coherent picture of what has been accomplished, especially during the last five years.

TL;DR: In this paper, the authors analyzed concurrent observations of particle chemical composition and water content from a continental nonurban (Grand Canyon) and an urban (Los Angeles) location to determine whether the water content of atmospheric particles is influenced by the presence of organics.

TL;DR: In this paper, a rigorous and computationally efficient thermodynamic model that estimates the state and composition of atmospheric inorganic species between the gas and aerosol phases is presented, and the estimation of important thermodynamic properties, equilibrium constants, ionic activity coefficients, water activity, and deliquescence points is described.

TL;DR: In this article, the authors evaluated the sensitivity of thermodynamic calculations of aerosol composition to common approximations and the choice of activity coefficient estimation method, and provided recommendations for treating weak electrolytes and for selecting an activity coefficient estimator in atmospheric gas-aerosol equilibrium calculations.
