The WCRP Coupled Model Intercomparison Project, Phase 5 (CMIP5), was a global climate model intercomparison project, coordinated by PCMDI (Program For Climate Model Diagnosis and Intercomparison) on behalf of the World Climate Research Program (WCRP) and provided input for the Intergovernmental Panel on Climate Change (IPCC) 5th Assessment Report (AR5).

The CMIP5 archive is managed via the Earth System Grid Federation, a globally distributed archive, with various "gateways" with advanced faceted search capabilities provided by a number of participating organisations. Full details are available from the PCMDI CMIP5 pages (see linked documentation on this record).

CEDA provides access to the UK Met Office contribution to the CMIP5 archive to UK researchers within the full distributed archive infrastructure and additionally holds a copy of the CMIP5 archive within its infrastructure to aid local use.
