Debriefing the First Year of the Climates Using Interactive Suites of Intercomparisons Nested for Exoplanet Studies (CUISINES).
Abstract
Model intercomparison projects (MIPs) have been widely used for decades by the Earth science community. For instance, the Coupled Model Intercomparison Project (CMIP) initiated in 1995 and currently in its version 6 and focuses on the differences in global climate model (GCM) responses to forcings for anthropogenic climate change. Model intercomparisons 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), our objective with CUISINES is 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 has already led to two successful virtual workshops, starting with BUFFET in September 2021 and following up with BUFFET-2 in October 2022. 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 Neptune: Comparing Atmospheric Models of Extrasolar Mini-neptunes Building and Envisioning Retrievals and Transits (CAMEMBERT) GCMs for Hot Jupiter: 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 that presentation, we propose an overview of the first findings of these various MIPs, both in term of science results and on the best recipes for building successful exoplanet model intercomparisons.- Publication:
