Short summary
We propose electrospray-surface enhanced Raman spectroscopy (ES-SERS) for measuring the surface chemical compositions of atmospherically relevant particles. The observations of surface aqueous sulfate and adsorbed water demonstrate a possible role of the water in facilitating the dissolution of sulfate from the bulk phase into its water layers. ES-SERS of submicron ambient aerosol particles collected in Hong Kong indicated an enrichment of sulfate and organic matter on the particle surface.
