ThousandWorlds: A benchmark for climate emulation of potentially habitable exoplanets

In three linesThousandWorlds is an ML benchmark for climate emulation of potentially habitable exoplanets. The dataset contains ~1800 simulations from 5 global climate models mapping 8 planetary parameters to 3D atmospheric fields. Three nested subsets and two evaluation protocols test 7 baselines; GP-based methods outperform standard deep learning.
