Lyon's air quality faces the Rhône-Alpes basin's challenging topography, with the surrounding Alps and the Massif Central partially enclosing the Rhône and Saône river confluence and trapping vehicle and industrial emissions under winter temperature inversions. The Mistral wind periodically delivers powerful clean air from the north, while calm summer periods drive ozone formation from vehicle and industrial NOₓ and VOC emissions across the metropolitan area.
