Short summary
Molecular acids in the atmosphere have implications for human health and air quality. Measurements of various acidic molecules were performed in the Colorado Front Range. Atmospheric concentrations of many acids increased during the day, indicative of sunlight-related production sources. A surface-level source of many acids persisting throughout day and night was observed. Traffic and agricultural activity were important anthropogenic sources of several acids near the measurement site.
