The World Climate Research Programme (WCRP) coordinates research on some of the worlds’ most pressing science questions. CMIP is a project of the WCRP, providing climate projections to understand past, present, and future climate changes. It is part of the WCRP Earth System Modelling and Observations (ESMO) Core Project which was formed to coordinate all modelling, data, and observations activities across WCRP and its key partners.
Under the guidance and at the direction of the WGCM, all CMIP activities are overseen by a coordinated pair of subcommittees: the CMIP Panel and the WGCM Infrastructure Panel (WIP). The CMIP Panel works with those organising various focused model intercomparisons to integrate them with the set of standard CMIP experiments to forge a synergistic experiment design for each new phase of CMIP. The WIP promotes coordinated development of infrastructure needed to support CMIP, most notably the archiving and serving of CMIP data.
A joint decision log for the CMIP Panel and WIP is publicly available by following this link. The decision log lists proposals which have been brought to the Panel and/or the WIP, the meeting in which the proposal was discussed, and whether the proposal was accepted or rejected. This log has been made publicly available to increase the transparency of the CMIP decision process and keep the community up-to-date on the planning of future CMIP phases.
In March 2022 the CMIP International Project Office was opened up to help coordinate and facilitate the design and application of future CMIP phases.
