Tucson's University of Arizona Mall air quality reflects the historic campus core, with vehicle traffic on the surrounding University Boulevard and the concentrated student pedestrian and transit character contributing local sources. The campus's extensive tree canopy provides natural filtration, while the Sonoran Desert basin creates periodic inversions and the walkable academic character reduces per-capita vehicle emissions, generally maintaining moderate Tucson metropolitan readings throughout most of the year.
