Little Rock's air quality reflects the Arkansas River valley's position in the south-central US, with vehicle emissions from I-30 and I-40 the primary local source in this mid-sized state capital. The surrounding Ouachita and Ozark foothills create modest topographic variation, while summer ozone from regional vehicle and agricultural sources and the flat Arkansas river plain provide the primary warm-season air quality influences.
