P00001 AEROSOL EFFECTS ON CLOUD MICROPHYSICAL PROCESSES PLAY A CRITICAL ROLE IN DETERMINING CLOUD RADIATIVE PROPERTIES AND PRECIPITATION FORMATION. IN THIS PROJECT, WE PROPOSE TO EXPLORE AEROSOL EFFECTS ON CLOUD RADIATIVE PROPERTIES USING AN EXPERIMENTAL APPROACH IN A CONTROLLED LABORATORY ENVIRONMENT. THE AEROSOL EFFECTS WILL BE STUDIED BY CREATING A TURBULENT MIXING CLOUD USING THE PI-CHAMBER FACILITY AND VARYING THE AEROSOL INJECTION RATE TO GET DIFFERENT CLOUD MICROPHYSICAL CONDITIONS. THE MEASURED, STEADY-STATE CLOUD DROPLET SIZE DISTRIBUTIONS WILL BE SUBSEQUENTLY USED TO QUANTIFY THE OPTICAL PROPERTIES OF CLOUDS AND WILL BE FURTHER UTILIZED FOR DEVELOPMENT OF PARAMETERIZATIONS FOR EFFECTIVE RADIUS. AEROSOL-CLOUD INTERACTIONS ARE A SIGNIFICANT CONTRIBUTOR TO THE UNCERTAINTIES OF EARTH S RADIATION BUDGET. THEREFORE, EXAMINING THE AEROSOL INDIRECT EFFECTS ARE CRUCIAL FOR NASA'S OBJECTIVE OF UNDERSTANDING EARTH SYSTEM AND CLIMATE CHANGE; FURTHERMORE, IT IS A NEEDED COMPONENT FOR RELIABLE AND PHYSICALLY-BASED SATELLITE DATA RETRIEVAL. THIS PROJECT WILL HELP TO UNDERSTAND THE PROCESSES DETERMINING CLOUD SIZE DISTRIBUTION SHAPE AND RELATED PARAMETERS SUCH AS DROPLET SIZE DISPERSION AND THE RATIO OF EFFECTIVE RADIUS AND MEAN VOLUME RADIUS, AND WILL THEREFORE LEAD TO IMPROVED PARAMETERIZATION OF CLOUD OPTICAL PROPERTIES FOR SATELLITE DATA RETRIEVAL AND CLIMATE CHANGE STUDIES.
