West Des Moines' air quality benefits from the flat Iowa prairie providing excellent wind dispersal, with vehicle emissions from I-235 and the surrounding financial services and technology campus corridor contributing relatively modest local sources. Agricultural ammonia from surrounding Polk County farming contributes secondary particulate formation, while summer regional ozone from Midwest agricultural and industrial sources is the primary warm-season concern and the flat Iowa terrain maintains moderate conditions.
