Abstract

NO, NO₂ and O₃ measurements from the Ground-based Cloud Experiment (GCE) campaign 1989 in the Po Valley in fog and fog free situations are presented. Extremely high concentrations of NO up to 9700 nmole m^-3 (217 ppbv) are shown. From the observations the fluxes are calculated using a flux-gradient-method. A detailed observation of the evolution of gas concentrations and fluxes during one observational day supports the significance of the oxidation of NO by O₃. The results strongly indicate that the soil is the main source of nitrogen oxides at this place.
