Leeds' air quality reflects its position at the heart of the West Yorkshire motorway network, with the M621 inner ring road and M1 and M62 corridors generating sustained NO₂ and PM2.5 across the metropolitan area. The surrounding Pennine hills to the west create a partial barrier to Atlantic ventilation on westerly days, while the Aire valley floor concentrates emissions under calm winter anticyclonic conditions.
