Arden-Arcade's air quality reflects the Sacramento Valley's temperature inversion problem, with vehicle emissions from US-50 and the surrounding mixed commercial and residential character of this unincorporated Sacramento County community contributing local sources. Winter tule fog inversions trap vehicle emissions, while summer ozone from the Sacramento Valley agricultural and metropolitan traffic corridor is the primary warm-season concern throughout the year.
