Short summary

The source, formation, transformation mechanisms and mixing state of particulate matter (PM) in high episodic events under different meteorological conditions in Hong Kong remain unclear. With high-resolution time-of-flight aerosol mass spectrometric measurement, we successfully demonstrated the dynamic and complex nature of PM transformation during high-PM episodes. This study revealed that not only regional transport but also local secondary formation is the culprit for high PM levels.
