Coupled Model Intercomparison Project

Definition

The Coupled Model Intercomparison Project (CMIP) is a framework for coordinated climate model experiments aimed at improving understanding of climate variability and change. It involves multiple climate models from different research groups around the world, allowing for comparison of their simulations of past, present, and future climate conditions. This collaboration helps identify strengths and weaknesses in models, contributing to enhanced predictive capabilities and informed policy decisions.
