Bauru's air quality reflects its position in the western São Paulo state plateau at 640 metres, with vehicle emissions from the SP-225 and surrounding highways the primary local source in this mid-sized interior Brazilian city. The elevated plateau position aids background dispersal compared to lowland areas, while dry season burning from surrounding São Paulo state agricultural land contributes seasonal PM2.5 variation between June and September.
