Night Chemistry Reduces Ozone

Researchers have determined that chemical processes at night remove atmospheric nitrogen oxides (NOx) in the marine boundary layer off the New England coast, which has the effect of reducing ozone formation the next day. Nocturnal nitrate radical (NO₃) and dinitrogen pentoxide (N₂O₅) form nitric acid, which rapidly deposits on the surface, making these chemical species unavailable for ozone-forming the next day. Ozone forms in the presence of sunlight in reactions between hydrocarbons and nitrogen oxides. The results demonstrate the importance of including nighttime chemistry in air quality models.
