Bellevue's air quality in Nebraska reflects the flat Missouri River valley position adjacent to Offutt Air Force Base, with vehicle emissions from US-75 and the surrounding military and suburban character contributing local sources. The flat Great Plains terrain provides good wind dispersal, while SAC-Offutt's military aviation operations contribute localised aviation NOₓ and the broader Omaha metropolitan regional ozone from vehicle and agricultural sources is the primary warm-season concern throughout the year.
