In the upcoming era of the James Webb Space Telescope, it becomes timely to focus community effort on benchmarking, comparing, and validating the performance of exoplanet models, both with respect to other models and to observations (when available).

This is the objective of the Climates Using Interactive Suites of Intercomparisons Nested for Exoplanet Studies (CUISINES) NExSS Science Working Group. The first intercomparison that happened within CUISINES is the TRAPPIST-1 Habitable Atmosphere Intercomparison (THAI). THAI compares the ExoCAM, LMD-G, ROCKE-3D and UM Global Climate Models (GCMs) on simulating TRAPPIST-1e. NExSS has hosted a successful THAI virtual workshop in September 2020 that brought together a community of 125 people and led to a peer-reviewed workshop report ( THAI data are still currently evaluated and about a dozen of papers are our are about to be published on these results.

With CUISINES we expect to expand THAI beyond only GCMs and rocky planets,  to perform intercomparison on any exoplanet model, from 3-dimensional general circulation models (GCMs) with or without interactive chemistry, Energy Balance Models (EBMs), 1D climate models, analytical models, and radiative transfer models from rocky to gas giant planets.

This project will identify and – where appropriate – smooth out differences between model predictions within the same model category (i.e. GCM vs GCM) or between categories (e.g. GCM vs. 1D climate models). It will also evaluate the model performances with comparisons to data (when available), as well as their computational efficiency. CUISINES data, multi-model outputs and scripts will all be made publicly available in a standardized format to guarantee easy reproducibility of the results.

This CUISINES webpage (under construction) will contain a link toward each intercomparison data via their logos.

New CUISINES intercomparisons are planned to be discussed at our second CUISINES workshop that will virtually happen in September 2021. You can read more details about it here:

This is the logo for the Sellers Exoplanet Environments Collaboration, which focuses on Earth Science, Heliophysics, Planetary, and Astrophysics multidisciplinary work. The logo is egg-shaped with a bold red outline. The interior shows the curve of Earth on the bottom of the image, with the sun peeking out beyond the curve. Above the sun, one red planet and one blue planet float. At the very top there is a hazy purple blob representing a nebula. The background is black with stars.

CUISINES is funded by SEEC, a NExSS team led by Avi Mandell (PI) and Ravi Kopparapu. You can find more information about SEEC here.
