Sacramento's air quality is shaped by the Central Valley's notorious temperature inversion problem, with the surrounding Sierra Nevada and Coast Range mountains trapping vehicle and agricultural emissions under persistent winter tule fog. Summer ozone from vehicle and agricultural emissions is the primary warm-season concern across the greater Sacramento metropolitan area.
