Short summary
Long-term observations at regionally representative sites can be used to challenge regional or global numerical models that underpin climate projections. Analysis of multi-decadal observations of aerosol microphysical properties in the remote marine boundary layer of the Southern Hemisphere characterises production and removal of marine aerosol on both short-term weather-related and underlying seasonal scales.
