US CLIVAR Reports

US Climate Variability and Predictability (CLIVAR) is a national research program with a mission to foster understanding of the ocean's role in the climate system. Coordinating and progressing research on outstanding climate questions, this collection of reports and white papers have been headed by US CLIVAR and supported by programs within five federal agencies which include: the National Aeronautics and Space Administration (NASA), the National Oceanic and Atmospheric Administration (NOAA), the National Science Foundation (NSF), the Department of Energy (DOE), and the Office of Naval Research (ONR).
