Short summary
Seasonal changes in chemical compositions, sources, and evolution for submicron aerosols in the megacity Beijing were investigated based on high-resolution AMS measurements. Carbonaceous fraction (OA+BC) constituted over 50 % of PM1 in autumn due to primary emissions, while SNA contributed 60 % to PM1 in other seasons. Secondary components (OOA+SNA) contributed ~ 60–80 % to PM1, suggesting that secondary formation played an important role in PM pollution. OA was in a relatively high oxidation state.
