DisclaimerThe Reduced Complexity Model Intercomparison Project (RCMIP) is about reduced-complexity, simple climate models and emulators. It focusses on evaluating these models by e.g. comparing them with observations of our climate system or examining their ability to emulate a range of CMIP6 coupled models. RCMIP is hence not one of the standard "MIPs" that are part of the Sixth Coupled Model Intercomparison Project's (CMIP6) (see CMIP6 protocols by the World Climate Research Programme here).
