Grand Forks' air quality benefits from the flat Red River Valley of the North providing excellent wind dispersal, with prevailing northwesterly winds from the Canadian prairies generally keeping readings at low to moderate levels. Vehicle emissions from US-2 and the University of North Dakota campus traffic are the primary local sources, while agricultural ammonia from surrounding North Dakota and Minnesota farming and summer regional ozone are the primary warm-season concerns throughout the year.
