Coupled Model Intercomparison Project (CMIP)

Definition

The Coupled Model Intercomparison Project (CMIP) is an international effort that aims to improve climate model simulations and projections by facilitating the comparison of different climate models. CMIP provides a standardized framework for climate modeling groups around the world to share their results, which helps in understanding the strengths and weaknesses of various models, thereby advancing climate science as a whole.
