CMIP and other experiments

CMIP and CORDEX

Climate projections are elaborated by international collaborations between research organisations that are referred to as projects or experiments. The major ones are:

• CMIP6, the sixth phase of the Coupled Model Intercomparison Project, which is the basis of the IPCC’s sixth assessment report (AR6, 2021–2023).
• CMIP5, which stands for Coupled Model Intercomparison Project 5, on which the fifth assessment report of the IPCC report relies upon.
• CORDEX for Coordinated Regional Climate Downscaling Experiment. In short, CORDEX is a high resolution version of the CMIP5 limited to some specific regions.
