Juazeiro do Norte's air quality benefits from its elevated position on the Chapada do Araripe plateau at 430 metres in the Ceará semi-arid interior, with generally good background dispersal characteristics. Vehicle emissions from the BR-116 and the growing pilgrimage city's road network are the primary sources, while drought conditions and dry season burning from surrounding semi-arid Caatinga landscape contribute seasonal PM10 episodes across the broader Crajubar metropolitan area.
