| Sea salt aerosol, generated by wave action of seawater, is one of the major sources of naturally produced airborne particles that play an important role in tropospheric chemistry and atmospheric environment. During transport, these marine particles can interact with anthropogenic pollutants and thus change their physicochemical properties including the composition, mixing state, and internal structure. Here we perform chemical imaging analysis of individual authentic particles collected during a cruise over South China Sea in May, 2016. We will present the physicochemical properties of individual particles and field evidence of possible chemical reactions in these particles, which may lead to chloride depletion. |
