Short summary
Methanesulfonic acid (MSA) is important to the CCN in the MBL. The uptake of MSA on particles is lacking in knowledge. The characteristics of MSA uptake on different particles were studied in the Southern Ocean. The MSA uptake on different particles was associated with particle properties. Uptake of MSA on sea salt particles was favored, while acidic and hydrophobic particles suppressed the MSA uptake. The results extend the knowledge of MSA formation and behavior in the atmosphere.
