Ciudad Obregón's air quality reflects the flat Sonoran Desert Yaqui River valley at 38 metres, with vehicle traffic on surrounding roads and the agricultural processing — Ciudad Obregón being Mexico's wheat capital — and manufacturing corridor contributing local sources. Windblown Sonoran Desert dust contributes elevated PM10, while the flat desert plain allows reasonable dispersal and Ciudad Obregón generally maintains moderate northwestern Mexican desert agricultural plain readings throughout most of the year.
