Rio Claro's air quality reflects its position in the São Paulo state interior plateau at 637 metres, with vehicle emissions from the SP-127 and the surrounding orange, sugarcane, and ceramic tile manufacturing industry contributing local sources. The elevated plateau position aids background dispersal, while dry season burning from surrounding São Paulo state agricultural land contributes seasonal PM2.5 variation, and the sugarcane belt's processing operations add localised organic emissions during the harvest season.
