Short summary

ClNO₂ and Cl₂ can be photolyzed by sunlight to produce a highly reactive Cl atom which affects air quality and climate. We observed high ClNO₂ and Cl₂ concentrations during a recent field study in east China. We analyzed the data and proposed a new hypothesis on the Cl₂ production mechanism. Yields of ClNO₂ and Cl₂ from N₂O₂ uptake were parameterized using observational constraints, and they can be used in air quality models to improve simulations of atmospheric photochemistry and air quality.
