Abstract
Seventeen days of detailed measurements of NO, NO2, O3, HNO3 and the frequency of NO2 photolysis—j(NO2)—were carried out in Claremont, CA, in September 1980. Under conditions when the rate of change of NO concentration is small, there must be a balance between formation and loss processes. In the classical photostationary state this balance is between NO2 photolysis: NO2 + hv → NO + O and reaction with ozone: NO + O3 → NO2 + O2. The results show that the latter reaction with ozone is inadequate to balance the formation step; a significant contribution is required from another NO oxidation process, possibly peroxy radical oxidation. If so, the inferred concentration of peroxy radicals shows a diurnal variation, peaking around solar noon.Keywords
