Campina Grande's air quality benefits from its elevated position on the Borborema Plateau at 550 metres in the Paraíba semi-arid interior, with the altitude generally aiding background dispersal compared to lowland Brazilian cities. Vehicle emissions from the growing metropolitan area are the primary source, while drought conditions and dry season agricultural burning from the surrounding semi-arid Caatinga landscape contribute seasonal PM10 and PM2.5 episodes.
