Arnsberg's air quality reflects the Ruhr river valley in the southern Sauerland, with vehicle traffic on the A46 motorway and the legacy of steel and manufacturing industry in this Sauerland market town contributing local sources. The surrounding Sauerland highlands create significant topographic variation compared to the flat Ruhr plain, while the valley's partial enclosure concentrates emissions under calm conditions and Atlantic westerlies provide the primary ventilation pathway.
