CLIVAR CMIP7 Climate Model Hackathon
- Organization: CLIVAR (World Climate Research Programme)
- Type: Workshop
- Location: Global
- Deadline: October 24, 2026
- Funding: No Funding
CLIVAR, the World Climate Research Programme's project on climate and ocean variability, is bringing researchers together for three days to test how well the new CMIP7 generation of climate models reproduces historical climate trends and multidecadal variability. It runs in person at the same time at NSF NCAR in Boulder, National Taiwan University in Taipei and the University of Tokyo, with some lectures and tutorials on analysing CMIP data and most of the time spent on collaborative projects aimed at papers ahead of the IPCC Seventh Assessment Report deadline. **What you get:** - Three days in person, 6 to 8 January 2027, at one of three hubs: NSF NCAR's Mesa Laboratory in Boulder, the Department of Atmospheric Sciences at National Taiwan University in Taipei, or RCAST at the University of Tokyo - Lectures and tutorials on how to use and analyse CMIP climate model data - Collaborative projects with climate scientists, aimed at publications ahead of the IPCC AR7 deadline of 15 March 2027 - A chance at limited travel support for flights or hotel, with priority for early-career researchers within 10 years of their PhD. It is confirmed for Boulder, funded by Spark Climate Solutions and the CMIP International Project Office; the Taipei form offers hotel support only **What you'll do:** - Analyse CMIP7 simulations of the historical period, comparing the models' trends and multidecadal variability with observations - Work out the relative roles of forced change and natural internal variability in historical trends, and the physical processes behind them - Spend most of the three days hacking on collaborative projects with other participants **Key dates:** - Applications close 24 October 2026 (no closing time is given) - Notifications by 31 October 2026, according to the application forms (the website says late October or early November) - Hackathon runs 6 to 8 January 2027 at all three hubs - 15 March 2027: the IPCC AR7 deadline the hackathon's papers are aimed at **More information:** - Each hub has its own application form, linked from the hackathon website - Venue details for the Taipei and Tokyo hubs are still to be announced, and the schedule is still being developed - The Boulder form says participants already attending the AMS Annual Meeting in Denver are expected to cover their own flights - The French climate modelling community is running a separate, coordinated Climathon on the French centres' CMIP7 Fast Track simulations
