In order to assess the role of aerosols in changing Artic climate and cloud properties, our objectives in this research cruise were to make surface based measurements of marine aerosol composition and cloud properties, and to conduct bubble tank experiments. Such aerosols may be produced locally (by sea spray or oxidation of gas-phase species) or transported from sources elsewhere. CCN (Cloud Condensation Nucleus) measurements made as function of aerosol size and super-saturation and will be used as input in cloud microphysical models to investigate their influence on aerosol-cloud feedback sensitivity. Bubble tank results will be used to provide a primary multicomponent sea-spray aerosol flux parameterisation for direct incorporation into the global aerosol modelling.
