Chongqing's air quality reflects the Sichuan Basin's near-complete topographic enclosure between the Daba and Wuling mountain ranges at 244 metres, with vehicle traffic on the Inner Ring Expressway and the extraordinary manufacturing, chemical, and automotive corridor contributing local sources. The basin's persistent cloudiness and calm conditions create extended pollution trapping, while the Yangtze and Jialing river valley humidity compounds the challenge and Chongqing maintains among China's more topographically challenged inland metropolitan environments.
