AGCM developed jointly by the Center for Cli-mate System Research (CCSR) of the University of Tokyo and the
Japanese National Institute for Environmental Sci-ences (NIES). The particular version of the CCSR/NIES AGCM
has been used for several international modeling ef-forts, including future projections for the Intergovernmental
Panel for Climate Change (IPCC, SRES) and the Atmos-pheric Model Intercomparison Project (AMIP).
