The primary goal of the World Climate Research Programme’s (WCRP) Coupled Model Intercomparison Project (CMIP) is to better understand past, present, and future climate changes arising from natural, unforced variability or in response to changes in forcing in a multi-model context. Successive generations of CMIP have seen the project grow in scope, with increasing process-specific Model Intercomparison Projects (MIPs) developed to address new and focused scientific questions, while continuing to play a critical role in the IPCC Assessment Reports. The latest phase, CMIP6, was the biggest yet with 131 participating models from 48 institutions, representing 26 countries across the globe and nearly 25 PB of CMIP6 data available across the 30 plus Earth System Grid Federation data nodes.

Under the guidance and direction of the Working Group on Coupled Modelling (WGCM), all CMIP activities are overseen by a coordinated pair of subcommittees: the CMIP Panel and the WGCM Infrastructure Panel (WIP). The WGCM, CMIP Panel and WIP are currently working hard in preparation for the next phases of CMIP, in particular CMIP7. In 2022 the results of the CMIP Community Survey provided in-depth, insightful, and honest feedback that will help support the development of future phases of CMIP. Based on these outcomes the CMIP Panel has sought to identify ways to increase the project’s scientific and societal relevance, improve accessibility, widen participation and reduce its own carbon footprint within the limits of available financial and human resources. This can only be achieved if a broad and diverse community, bridging traditional divides, is involved in the planning, definition, and co-creation of future CMIP phases. Therefore, the CMIP panel and WIP have established a number of CMIP7 Task Teams to support the design, scope, and definition of the next phase of CMIP and evolution of CMIP infrastructure and future operationalisation.

This Townhall will be an opportunity for representatives from the CMIP Panel, WIP and the CMIP7 Task Team leads to give an update on their activities, highlight engagement opportunities and seek feedback from the EGU23 attendee community representing both CMIP data producers and users from the increasingly wide and diverse range of CMIP downstream users. The discussion and outputs of this session will feed directly into the CMIP7 task teams’ ongoing work and the wider CMIP7 planning and experimental design process.
