TL;DR: Comparison of these findings to model predictions based on aerosol and precipitation composition data from long-term monitoring networks suggests nitryl chloride production in the contiguous USA alone is at a level similar to previous global estimates for coastal and marine regions and that a significant fraction of tropospheric chlorine atoms may arise directly from anthropogenic pollutants.

TL;DR: In this paper, a new chemical removal method was used to measure hydroxyl (OH) in a California forest environment using laser-induced fluorescence in low pressure detection chambers (called Fluorescence Assay with Gas Expansion (FAGE)) using the Penn State Ground-based Tropospheric Hydrogen Oxides Sensor (GTHOS).

TL;DR: The chemically speciated fluxes presented here comprise a unique and novel dataset that quantifies the dry deposition velocities for a variety of trace gases in a typical forested ecosystem, and suggests that dry deposition is the dominant daytime sink for small, saturated oxygenates.

TL;DR: In this paper, an extensive set of emission factors (EFs) for over 80 gases and 5 components of submicron particulate matter (PM_1) from three wildfires in the western U.S. were measured from aircraft during the Studies of Emissions and Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys (SEAC^4RS) and the Biomass Burning Observation Project (BBOP).

TL;DR: In this article, the authors studied the effect of varying levels of surfactant on gas-aerosol reaction rates and found that the presence of 3.5wt% SDS in the aerosol, which corresponds to a monolayer surface coverage of 2×1014 molecules cm-2, suppresses the N2O5 reaction probability by approximately a factor of ten, independent of relative humidity.
