Chihuahua's air quality reflects the flat Chihuahuan Desert plain at 1,423 metres, with vehicle traffic on surrounding roads and the maquiladora manufacturing, cattle, and agri-food corridor contributing local sources. Windblown Chihuahuan Desert dust contributes elevated PM10 during dry windy periods, while the elevated semi-arid plateau provides reasonable dispersal on most days and Chihuahua generally maintains moderate to good northern Mexican desert plateau metropolitan readings throughout most of the year.
