Abstract
Two photochemical models were applied to the area of Bologna (Italy). A
simple single cell variable volume flow reactor (PBM - Photochemical Box
Model) was employed to simulate the relationship between pollutant emission
and ambient air quality. The model represents the Bologna area as a single cell
20 km in both length and width, with variable height representing the changing
depth of the mixed layer.
Moreover, the photochemical Eulerian CALGR1D model was applied to
predict the hourly, three-dimensional concentration fields for ozone focusing on
the Bologna urban area.
The influence of a reduction in NOx emission was investigated.
