Davenport's air quality reflects the Mississippi River valley's flat terrain in the Quad Cities metropolitan area, with vehicle emissions from I-74 and I-80 and the surrounding agricultural processing and manufacturing industry contributing elevated PM2.5. The Mississippi River provides a natural ventilation corridor, while prevailing westerlies from the Iowa prairie generally keep readings at moderate Midwest levels and summer regional ozone from agricultural sources is the primary warm-season concern.
