CUISINES of the worlds


Thomas Fauchez


Research Scientist at NASA's Planetary Systems Lab



Model intercomparison projects (MIPs) have been widely used for decades by the Earth science community. They are crucial to improve models? reliability, mitigate model dependencies, track down bugs and to provide benchmarks for new models. Additionally, they provide the community a way to assess and report the degree of consensus that exists between the models, and the associated uncertainties and origins of uncertainty that exist with respect to the conclusions drawn from the use of such models. Leveraging the results of the TRAPPIST-1 Habitable Atmosphere Intercomparison (THAI), we developed the Climates Using Interactive Suites of Intercomparisons Nested for Exoplanet Studies (CUISINES) to respond to the need within the exoplanet modeling community to have a structure to run and host intercomparisons like the Earth science community currently does. Such intercomparisons are especially vital in the (relatively) data-poor realm of exoplanet science. CUISINES kicked off in September 2021 at the BUFFET virtual workshop and a variety new MIPs have been proposed and are already running. CUISINES data, multi-model outputs and scripts will all be made publicly available in a standardized format to guarantee easy reproducibility of the results. As with THAI, each CUISINES intercomparison has a gastronomy-related acronym: GCMs for pre-industrial Earth: Comparison of Reference Exoplanet Models of Earth (CREME) GCMs for Mini Neptunes: Comparing Atmospheric Models of Extrasolar Mini-neptunes Building and Envisioning Retrievals and Transits (CAMEMBERT) GCMs for Hot Jupiters: MOdeling the Circulation of Hot exoplanets Atmospheres (MOCHA) GCMs for Earth-like exoplanets in a large parameter space with quasi Monte Carlo: Sparse Atmospheric MOdel Sampling Analysis (SAMOSA) EBM: Functionality of Ice Line Latitudinal EBM Tenacity (FILLET) 1D models: Photochemical model Intercomparison for Exoplanets (PIE) RT tools: Modeling Atmospheric Lines By the Exoplanet Community (MALBEC) In this presentation we will demonstrate why model intercomparisons are crucial for the exoplanet community and will discuss the first results.
