Abstract

In the Osaka area, high concentrations of NO2 are observed in spring. To understand the relative roles and amounts of transported background ozone, photochemical ozone, transported NO2, and primary emitted NO2 in controlling NO2 formation in the Osaka area, a three-dimensional photochemical air pollution simulation model was applied based on the actual meteorological and emission conditions. Simulated results reveal that photochemical reactions play an important role in the formation of the springtime high concentrations of NO2 in Osaka.
