Short summary
A potential aerosol mass (PAM) reactor expedites slow atmospheric oxidation reactions and enables the observation of chemical aging processes and the determination of the aerosol-forming power of an air mass. A PAM reactor was deployed at Baengnyeong Island in the Yellow Sea. Experimental results confirm the key role of SO2 in generating secondary aerosols in northeast Asia, and the contribution of organics to secondary aerosols is more variable during transport in the atmosphere.
