CMIP5 - Coupled Model Intercomparison Project Phase 5
The CMIP5 output from CCSM4 provided through the Earth System Grid represents the time-varying projections of the various simulations defined by the CMIP5 protocol. The output includes averages over a range of time scales, hours to a full year, of important physical, chemical, and biological values from the atmosphere, ocean, land, and sea-ice components of CCSM4.
The Community Earth System Model (CESM) is a fully-coupled, global climate model that provides state-of-the-art computer simulations of the Earth's past, present, and future climate states.
CESM is sponsored by the National Science Foundation (NSF) and the U.S. Department of Energy (DOE). Administration of the CESM is maintained by the Climate and Global Dynamics Laboratory (CGD) at the National Center for Atmospheric Research (NCAR).
