Indianapolis' air quality reflects the flat Indiana Midwest terrain that allows reasonable wind dispersal, with vehicle emissions from the I-465 beltway and the surrounding interstate network the primary local source. Regional ozone from agricultural and industrial sources across the broader Ohio Valley can elevate summer readings, while the flat landscape prevents the topographic trapping seen in hillier US cities.
