(273i) New Findings Based on Airborne Measurements of Aerosol Particles and Stratocumulus Clouds off the California Coast

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.
