Abstract:

The long-term goal of this project is to predict the radiative properties of the marine atmosphere based on aerosol and cloud properties. The objective of the project is to improve our understanding of the role of aerosols in the Marine Boundary Layer and our ability to simulate marine stratocumulus clouds as a function of aerosol properties and the large-scale meteorology. The proposed research consists of laboratory, aircraft experiment, and modeling studies that address the hygroscopic properties of aerosols and aerosol-cloud relationships in marine stratocumulus MSc clouds. A CIRPAS Twin Otter field experiment took place in July-August 2011 over the eastern Pacific Ocean off the coast of Monterey, CA. That experiment addressed the response of MSc to aerosol perturbations, in collaboration with Professors Bruce Albrecht of the University of Miami, Armin Sorooshian of the University of Arizona, and Lynn Russell of UCSD. We designated this experiment as the Eastern Pacific Emitted Aerosol Cloud Experiment, E-PEACE. Evaluation of the E-PEACE data is continuing.
