The WIP is a Working Group on Climate Modelling (WGCM) subcommittee charged with coordinating infrastructure support for CMIP (see “Terms of Reference“). It works with projects funded to develop software and supporting infrastructure that facilitates access to and analysis of the CMIP model output. It defines specifications and standards that ensure model output is written in a common structure and format, and that it is archived and made accessible worldwide in a common way. More generally, the WIP provides guidance and oversees infrastructure development so that it will be fit for its purpose and meet the scientific needs of CMIP and other MIP projects.
The WIP works closely with the WGCM CMIP Panel, which oversees the evolving design of the CMIP experiments and coordinates the various activities contributing to the science of CMIP.
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.
The WIP maintains a website, which can be found at wcrp-cmip.github.io/WCGM_Infrastructure_Panel.
