São Carlos' air quality reflects its position in the São Paulo state interior plateau at 856 metres, with vehicle emissions from the SP-310 Washington Luis highway and the university research and technology park character of this major Brazilian science city contributing relatively modest local emissions compared to neighbouring industrial São Paulo state cities. The elevated plateau position aids background dispersal, while dry season agricultural burning contributes seasonal PM2.5 variation across the broader interior.
