Abstract:

The Climates Using Interactive Suites of Intercomparisons Nested for Exoplanet Studies (CUISINES) is a Working Group of the NASA’s Nexus for Exoplanet Systems Science (NExSS). It is a community intercomparison meta-framework for exoplanet climate, chemistry, and observables—built to turn model predictions into benchmarked, reproducible, mission-ready products. It began in 2017, when exoplanet GCM teams recognized that, as in Earth science (CMIP/PMIP), rigorous model intercomparison is the only credible way to reduce model dependence for habitable-zone rocky planets. Led from NASA GSFC, we launched THAI for TRAPPIST-1e and showed that cloud-physics differences alone can change JWST observing time for atmospheric detections by >50%, directly impacting how we plan and interpret. THAI’s open datasets and Python tools have made it a global reference (348 citations), now used to validate GCMs as well as 2D and 1D models worldwide. Beyond the scientific findings, THAI’s success also came from its strong commitment to accessibility: all outputs are publicly hosted on our website and supported by user-friendly Python tools on Github for extraction, visualization, and analysis. This combination—high-impact intercomparison science paired with truly open, reusable infrastructure—served as the pilot and guiding model for the broader CUISINES framework. CUISINES supports a systematic approach to evaluating the performance of exoplanet models and provides a framework for conducting community-organized exoMIPs. It adapts Earth climate community practices specifically for the needs of the exoplanet researchers, encompassing a range of model types, planetary targets, and parameter space studies.
 
In this presentation, we will review the objectives of the 11 CUISINES exoMIP dishes and will discuss how to strengthen the Japanese community contribution to the project. Plenty of CUISINES stickers will be distributed!
