Short summary
We have investigated the cloud condensation nuclei (CCN) properties in the trade wind marine boundary layer of the western North Atlantic during the dust season. Little is known about the CCN influencing cloud optical properties in that region. High mass concentrations of mineral dust were observed, but the number concentrations of mineral dust and sea salt were not high enough to influence CCN properties, and the CCN were likely to be dominated by a mixture of sulfates and organic species.
