North Little Rock's air quality reflects the Arkansas River valley's flat terrain adjacent to Little Rock, with vehicle emissions from I-40 and the surrounding manufacturing and logistics industry contributing local sources. The Arkansas River corridor channels prevailing westerly winds through the metropolitan area, while summer ozone from regional vehicle and agricultural sources across the broader Arkansas Valley airshed is the primary warm-season concern throughout the year.
