Coupled Model Intercomparison Project

In climatology, the Coupled Model Intercomparison Project (CMIP) is a collaborative framework designed to improve knowledge of climate change. It was organized in 1995 by the Working Group on Coupled Modelling (WGCM) of the World Climate Research Programme (WCRP). It is developed in phases to foster the climate model improvements but also to support national and international assessments of climate change. A related project is the Atmospheric Model Intercomparison Project (AMIP) for global coupled ocean-atmosphere general circulation models (GCMs).

Coupled models are computer-based models of the Earth's climate, in which models of different subsystems (such as the atmosphere, oceans, land, ice) are "coupled" together, and interact in simulations.
