The purpose of ACCESS is to bring together young researchers in atmospheric chemistry and representatives of the principal federal government agencies that fund atmospheric chemistry research to engage in scientific discussion and interaction. The meetings will forge future professional relationships, and the entire atmospheric science community will benefit by becoming more aware of innovations in atmospheric chemistry through presentations by ACCESS participants and through these interactions. Participation in ACCESS and the GRC is jointly sponsored by the U.S. Department of Energy (DOE), the National Aeronautics and Space Administration (NASA), the National Oceanographic and Atmospheric Administration (NOAA), the National Science Foundation (NSF), and the U.S. Environmental Protection Agency (EPA).
