Nancy's air quality reflects the Meurthe river valley at the Lorraine-Alsace border, with vehicle traffic on the A31 motorway and the surrounding industrial and logistics corridor contributing local sources in this major Lorraine university city. The Moselle valley provides ventilation on westerly winds, while the Vosges hills to the east create modest topographic variation and cross-border emissions from the Luxembourg and Saarland corridors influence the regional background throughout the year.
