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: Aircraft measurements of NO3 and N2O5 show that the N2 O5 uptake coefficient on aerosol particles is highly variable and depends strongly on aerosoli composition, particularly sulfate content, and suggest a stronger interaction between anthropogenic sulfur and nitrogen oxide emissions than previously recognized.

TL;DR: It is found that ozone production occurs at lower NOx and much larger VOC concentrations than does its summertime urban counterpart, leading to carbonyl (oxygenated VOCs with a C = O moiety) photolysis as a dominant oxidant source.

TL;DR: In this paper, the yields of organic nitrates and of secondary organic aerosol (SOA) particle formation were measured for the reaction NO3+β-pinene under dry and humid conditions in the atmosphere simulation chamber SAPHIR at Research Center Julich.

TL;DR: In this article, the authors used airborne and ground-based measurements of organic aerosol (OA) in the Los Angeles (LA) Basin, California made during May and June 2010 to assess the amount of SOA formed from diesel emissions.
