This site now provides access to results from experiments that were part of the contribution of the Zero Emissions Commitment ModelIntercomparison Project (ZECMIP) to the Coupled Climate Carbon Cycle Model Intercomparison Project (C4MIP). Contacts for individual modelling groups can be found on the Participants page. See the Experiments page for a description of the experimental design. The data from this project is now freely available. Files, which contain model results, can be downloaded from the Results page. Links to papers or web sites which provide background or a synthesis of some of the key results from this project can also be found on the Documents page.

If you publish articles that use the results from this project, please acknowledge the "ZECMIP contributors" and reference one or both of the following papers:
