Davis' air quality reflects the Sacramento Valley's temperature inversion problem, with vehicle emissions from I-80 and the UC Davis campus and surrounding agricultural research operations contributing local sources. Winter tule fog inversions trap vehicle emissions, while summer ozone from the Sacramento Valley agricultural corridor is the primary warm-season concern and the surrounding Yolo County rice and tomato farming adds agricultural PM2.5 during the autumn harvest season.
