Mecca's air quality reflects the Wadi Ibrahim valley's enclosed granite mountain position at 277 metres in the Hijaz, with vehicle traffic on surrounding expressways and the extraordinary Hajj and Umrah pilgrimage concentration generating periodic intense vehicle and crowd density. The Hijaz Desert's windblown sand contributes elevated PM10 during sandstorm events, while the valley's topographic enclosure concentrates pilgrim transport vehicle emissions and Mecca's unique cyclic pilgrimage traffic represents the world's most extraordinary periodic urban air quality challenge.
