Description :
The aim of this research was to reveal evidence of the complete diurnal process by which high concentrations of lower-atmospheric ozone are typically transported across the Phoenix (Arizona) Valley. The spatial and temporal patterns of diurnal concentrations and the associated atmospheric flow patterns were examined on three spatial scales for a two-month period during summer 1998. The synoptic-scale weather pattern provided a calm, clear background atmosphere. Taken together, the upslope and downslope transports of ozone produced a sloshing of the aerosol along the eastern side of the valley basin, affecting the eastern metropolitan population twice daily.
