5 February @ 19:00 – 22:00 GMT
Context and workshop objectives
An ongoing challenge for climate data users is the time taken between the global climate simulations and the provision of data relevant to end users. CMIP, together with colleagues in CORDEX, ISIMIP, ISMIP7, GlacierMIP and others, have identified the need for a collaborative effort to streamline this process. There are opportunities for progress through sharing of best practice, investigating the potential of shared selection criteria, improved communication and data infrastructures, and the development of community tools.
To progress towards this shared goal, the aims of this collaborative workshop are:
- Identifying the issues/challenges in the current framework, both scientific and technical.
- Developing shared understanding of model selection techniques/approaches used across the communities.
- Determining if shared criteria for model selection is required and possible.
- Establishing tangible structures to support improved communication between modelling centres and downstream activities.
- Accelerate the process from the creation of global simulations to regional downscaling and impact modelling and finally, the provision of data to end users.
- Determining the needs for and identifying pathways to developing and funding the scientific and technical frameworks required to deliver to users.
- Realistically assessing whether achieving this within CMIP7 is feasible, or the focus should be on laying groundwork for a longer term plan.

Time (UTC) | Topic |
---|---|
19:00-19:05 | Welcome and housekeeping (CMIP IPO) |
19:05-19:20 | Meeting objectives (Christian Steger, DWD) |
19:20-19:35 | Setting the context An example of challenges faced by users in the current framework (Sven Kotlarski, Meteo Swiss) |
19:35-20:05 | Sharing examples of current best practice EURO-CORDEX for CMIP6 (Stefan Sobolowski, University of Bergen) CORDEX-Australasia CMIP6 for Australian national projections (Michael Grose, CSIRO) Model selection for RCM downscaling in ISMIP6 (Céline Agosta, LSCE/IPSL) The ISIMIP approach (Lisa Novak, PIK Potsdam) |
20:05-20:35 | BREAKOUT GROUPS: Scientific challenges BOG 1 & 2: Ensemble sub-selection: is a common criteria/minimum set of evaluation metrics/framework to serve all communities possible or desired? BOG 3: What do model development innovations mean for model selection e.g., the CMIP7 focus on CO2 emission-driven simulation, increasing resolution and AI/ML? BOG 4: Understanding, quantifying and communicating uncertainty |
20:35-20:45 | BREAK: Time for a drink and stretch! |
20:45-21:15 | BREAKOUT GROUPS: Other challenges BOG 5: Constraints on the availability of the required GCM/ESM model data – timing, provision of all required data, including temporal frequencies and extensions BOG 6: Sustained and supported infrastructure to store, deliver and provide user friendly platforms for analysis, framework for coordinated exchange between communities. BOG 7: Speeding up the process from creation of the global simulations until data/information reaches the end user including potential role of community developed tools to support model evaluation and selection BOG 8: Balancing competing needs – funding, politics and ensuring equity, and supporting training and capacity building in a global community effort |
21:15-21:40 | Feedback from breakout groups |
21:40-21:55 | What have we learned during the workshop and what are next steps? Immediate actions required Follow up workshop (virtual/in person) Format of outcomes – commentary paper, whitepaper etc. |
21:55-22:00 | Final comments and meeting close |
