Recent aircraft field experiments with the Center for Interdisciplinary Remotely Piloted Aircraft Studies (CIRPAS) Twin Otter have yielded a rich set of data that have been analyzed to explore various aspects of aerosol-cloud interactions. These campaigns, based out of Marina, California in the July-August time frame, include the Eastern Pacific Emitted Aerosol Cloud Experiment (E-PEACE, 2011), Nucleation in California Experiment (NiCE, 2013), and the Biological Ocean Atmospheric Study (BOAS, 2015). This presentation will discuss the following: (i) differences between cloud chemical composition between coupled and decoupled marine stratocumulus clouds for dissolved non-water substances; and (ii) differences between cloud and aerosol composition during periods with and without wildfire influence.
