Nîmes' air quality benefits from the Languedoc plain's position between the Cévennes to the northwest and the Rhône delta to the east, with periodic Mistral wind events providing powerful clean air from the north and the Rhône-Gard corridor. Vehicle traffic on the A9 and A54 motorways and summer tourist traffic are the primary local sources, while calm Mediterranean anticyclonic conditions allow ozone to accumulate from vehicle and agricultural emissions, and the flat Languedoc plain generally allows reasonable dispersal on most wind days.
