Guadalajara's air quality reflects Mexico's second city in the Atemajac Valley's partial topographic enclosure at 1,566 metres, with vehicle traffic on the Periferico and the surrounding manufacturing, electronics, and automotive corridor contributing local sources. The valley's topographic enclosure concentrates emissions under inversions, while the elevated altitude worsens ozone formation and Guadalajara's combination of vehicle density and valley topography makes it one of Mexico's more challenging provincial metropolitan air quality environments throughout the year.
