The CMIP Panel is a Working Group on Climate Modelling (WGCM) subcommittee charged with overseeing the evolving design of the CMIP experiments and with coordinating the various activities contributing to the science of CMIP. It works with the scientific leaders of specialized model intercomparisons that contribute to CMIP, and it has traditionally been responsible for identifying experts to develop the forcing datasets needed for some of the experiments.
The CMIP Panel works closely with the WGCM Infrastructure Panel (WIP), which coordinates infrastructure support for CMIP across a broad contributor community during the project delivery phase, and is responsible for many of the technical specifications for model output.
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.
