  • Beschreibung: <jats:title>Abstract</jats:title><jats:p>Nitryl chloride (ClNO<jats:sub>2</jats:sub>) acts as a source of highly reactive chlorine atoms as well as an important NO<jats:sub><jats:italic>x</jats:italic></jats:sub> reservoir. Measurements of ClNO<jats:sub>2</jats:sub> at an operational U.K. landfill site are reported here for the first time. A peak concentration of 4 ppb of ClNO<jats:sub>2</jats:sub> was found with a peak mean nighttime maximum of 0.9 ppb. Using models based upon the photolysis of observed ClNO<jats:sub>2</jats:sub> and atmospheric chlorine chemistry, chlorine atom concentrations reaching in excess of 1.20 × 10<jats:sup>5</jats:sup> molecules/cm<jats:sup>3</jats:sup> in the early morning following sunrise are calculated. These concentrations are approximately 10 times higher than previously reported in the United Kingdom, suggesting a significant impact on the oxidizing capacity around such sites. Given the ubiquity of landfill sites regionally and globally, and the large abundances of Cl atoms from the photolysis of ClNO<jats:sub>2</jats:sub>, chlorine chemistry has a significant impact on ozone formation and volatile organic compounds oxidation as shown by WRF‐Chem modeling.</jats:p>
