Airborne measurements of ozone concentrations in background air and power plant plumes
Ozone plays an important role in the physicochemical interactions between plumes and background air. During two field programs conducted at Cordemais in fall 1984 and at Le Havre in fall 1985, concentration measurements were performed in background air and in the plumes of fossil-fuel fired power plants. In background air, the daily average ozone concentration varied between 15 and 60 ppb depending on solar irradiation, pollution level and atmospheric stability. Maximum values of 100 ppb were observed in industrial area plumes. In the power plant plume, consumption of atmospheric ozone by emitted NO is important during the first 5 km downwind of the power plant but does not totally explain some important formation of NO2 identified at short distances downwind of the power plant.
