Abstract:

The ultimate goal of this study, as originally conceived, is the determination of aerosol hygroscopicity and its impact on physical e.g., size and optical e.g., scattering coefficient properties of marine aerosols on large spatial scales. In the course of our analysis, it has further become clear that relating aerosol hygroscopicity to chemical composition, particularly organic composition, is an integral component of this research. Additionally, associated with the renewal of funding in 2002, goals concerning the interaction of marine aerosols with marine boundary layer MBL clouds have been added. These new goals include 1 assessment of the relative impacts of purely meteorological and aerosol factors on cloud albedo, 2 determination of the impact of very large CCN on cloud albedo, 3 assessment of the impact of cloud processing on aerosol light scattering, and 4 explore, observationally, the impact of organics on CCN activation in MBL clouds.
