The Eighth Symposium on Aerosol–Cloud–Climate Interactions is organized by the AMS Committee on Atmospheric Chemistry and is sponsored by the American Meteorological Society. The theme for the 2016 AMS Annual Meeting, “Earth System Science in Service to Society”, weaves the many parts of AMS into a common core. Emphasizing the academic and research strength of AMS, the theme also connects that research to the benefits that society gains from our science.
