Abstract : The primary goals of this research were to address the following key questions regarding marine aerosol/ cloud interactions: (1) What factors control the abundance and vertical distribution of aerosol in the marine boundary layer? (2) How do these factors affect the formation and lifetime of marine clouds? These questions have been addressed through a combination of modeling and experimental approaches, as described below. The goal of the modeling component was to produce a model description of aerosol evolution and aerosol / cloud interaction that can be applied to a variety of marine boundary layer scenarios. The specific objective of this component was to develop a model for prediction of the effects of aerosol characteristics on cloud formation and evolution, and, in turn, the effects of cloud processes on the marine aerosol. The models built in this project can be used to study the role of aerosol in cloud modification, including ship tracks and indirect climate effects. The goals of the experimental component were to develop new measurement techniques aimed at elucidating some important aerosol / cloud interactions, and to adapt and use these techniques in field work involving characterization of marine aerosol. A particular objective was the development of techniques for determination of size dependent particle properties with high time resolution.
