Ahlen's air quality reflects the flat Westphalian plain in the Rhine-Ruhr eastern zone, with vehicle traffic on the A2 motorway and surrounding manufacturing legacy industry contributing local sources. The flat North Rhine-Westphalian plain provides reasonable dispersal on most days, while the broader Ruhr industrial background elevates baseline PM2.5 and consistent Atlantic westerlies provide the primary ventilation throughout the year.
