Aerosol properties have been measured simultaneously in the free troposphere and marine boundary layer of the northeast Atlantic during July 1994 and 1995, in order to survey and classify the properties of the various air masses advecting to the region which will serve as the base for the 1997 ACE-2 experiment. An overview is given of chemical composition, size distributions and radiative properties for both sites. European pollution is found to affect the aerosol properties in the marine boundary layer and the free troposphere of the studied area, leading to higher non-sea-salt sulfate concentration, higher scattering coefficient, higher light absorption and more numerous CCN.
