Seventeen days of detailed measurements of atmospheric concentrations of NO, NO/sub 2/, O/sub 3/, and HNO/sub 3/ and the frequency of NO/sub 2/ photolysis led researchers to agree that a balance must exist between formation and loss processes under conditions when the rate of change of NO concentration is small. In the classical photostationary state, this balance is between NO/sub 2/ photolysis and the reaction with ozone. Test results show that the reaction with ozone is inadequate to balance the formation step; a significant contribution is required from another NO oxidation process, possibly preoxy radical oxidation. If so, the inferred concentration of peroxy radicals shows a diurnal variation, peaking around solar noon.
