NO/NO2/O3 photostationary state in Claremont, California
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 yields NO + O and reaction with ozone: NO + O3 yields 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.
