Coupled Model Intercomparison Project (CMIP)

Definition

The Coupled Model Intercomparison Project (CMIP) is a collaborative framework designed to facilitate the comparison of different climate models and their projections for future climate scenarios. By standardizing experimental protocols, CMIP enables scientists to assess model performance, understand climate forcings, and explore feedback mechanisms that influence climate change outcomes across various models.
