Grand Rapids' air quality is generally good for a Midwest US city, benefiting from Lake Michigan's consistent westerly winds providing clean maritime air from the west. Vehicle emissions from the I-96 and I-196 corridors are the primary local source, while industrial emissions from West Michigan's manufacturing base contribute moderate PM2.5. The flat western Michigan terrain generally allows good wind dispersal throughout the year.
