We present an aerosol cloud condensation nuclei (CCN) closure study over the north-east Atlantic Ocean using six approximating methods. The CCN number concentrations (N-CCN) were measured at four discrete supersaturations (SSs; 0.25 %, 0.5 %, 0.75% and 1.0 %). Concurrently, aerosol number size distr...
