We report in situ measurements of N<sub>2</sub>O<sub>5</sub>, NO<sub>2</sub>, and O<sub>3</sub> in Contra Costa County, California during January 2004. Mixing ratios of N<sub>2</sub>O<sub>5</sub>, an intermediate compound in the atmosphere's nocturnal cleansing process, ranged up to 200pmol/mol at night. The highest N<sub>2</sub>O<sub>5</sub> concentrations were correlated with low O<sub>3</sub> and high NO<sub>2</sub> concentrations. The calculated steady state lifetime for N<sub>2</sub>O<sub>5</sub> ranged from 5 to 30min. The total HNO<sub>3</sub> produced by N<sub>2</sub>O<sub>5</sub> hydrolysis over a 14h night was comparable to ambient NO<sub>2</sub> concentrations, and is estimated to be a factor of nine bigger than the HNO<sub>3</sub> produced during the day. |
