Short summary

We address, on the molecular level, the potential for, and consequences of, surface property variations in aerosol particles in the atmosphere. Aerosol surface aging changes the interfacial chemistry, giving rise to marked variations in the ice nucleation ability of the surface. This study provides new insights into atmospheric processes, particularly cloud formation and aerosol aging in the atmosphere, with potential implications for the pharmaceutical and food industries.
