This study focuses on seasonal and interannual variations of PM2.5, surface O3, and smog from 2003 to 2015 in six Ontarian cities, including Sarnia, Hamilton, and Toronto in the south, and North Bay, Sudbury, and Sault Ste. Marie in the north. All cities had the highest PM2.5 and smog events in summer and the highest O 3 in spring. PM2.5 and smog events were greater in the southern cities than in the northern ones; the pattern is the opposite for surface O3. For most cities, the annual PM2.5 decreased insignificantly while surface O3 increased significantly. The diurnal variation of surface O3 altered by rains in an Ontarian city, Mississauga, is also investigated for the warm seasons of 2014 and 2015. At daytimes, surface O3 during rain decreased by 7 ppb, resulting from less photochemical production. At night, O3 during rain increased by 6 ppb, attributing to the chemical reduction of NO.
