The recent explosive population growth in Phoenix, Arizona is forcing policy-makers to develop an increased understanding of air quality meteorology in the desert setting. In this investigation, the long-term smoke/haze data base from Phoenix is analyzed to determine the magnitude of temporal changes in smoke/haze frequencies and durations. The results reveal no changes in smoke/haze frequency and intensity, but significant increases in the duration of these events. The findings appear to be related to the impact of the growing urban heat island on the structure of local inversion layers. The results suggest a link between urban-induced temperature and wind changes and air quality levels within a growing metropolitan area.
