TL;DR: In this article, the authors present a method for estimating cooking organic aerosol in ambient datasets based on the fractions of organic mass fragments at m/z 55 and 57: their data points fall into a V-shape in a scatter plot, with strongly influenced HOA data aligned to right arm and strongly influenced COA data points aligned to the left arm.

TL;DR: In this paper, the authors reviewed current knowledge of the emissions of these oxVOCs by plants and the factors that control them, and also provided an overview of sources, sinks, and concentrations found in the atmosphere.

TL;DR: It is found that never-before-identified low-volatility organic species, which are highly functionalized, explain a major fraction of the total particle nitrate mass measured by the traditional aerosol mass spectrometer, shows that these organic nitrates are likely derived from oxidation of biogenic hydrocarbons and persist in the particle phase for only a few hours.

TL;DR: Mean annual biomass burning contributions to the bulk particulate matter (PM(X)) load were quantified in a southern-European urban environment (Barcelona, Spain) with special attention to typical Mediterranean winter and summer conditions by means of the Multilinear Engine.

TL;DR: In this article, the authors present results from the international field campaign DAURE (Determination of the sources of atmospheric Aerosols in Urban and Rural Environments in the Western Mediterranean), with the objective of apportioning the source of fine carbonaceous aerosols.
