ThousandWorlds: Exoplanet Climate Simulations Across 1,760 Scenarios

AstroAutomata's ThousandWorlds benchmark contains 1,760 simulated exoplanet climates generated across 5 different General Circulation Models (GCMs). The dataset includes eight continuous planet parameters as inputs and outputs time-averaged climate fields on a 32 x 64 latitude-longitude grid. It was last updated on June 23, 2026, and features three nested benchmark subsets and eight released baseline methods for evaluation.

Use Cases

• Benchmarking climate emulation models based on the eight continuous planet parameters and GCM labels.
• Training surrogate models to predict climate fields from planetary parameters based on the 1,760 simulation scenarios.
• Evaluating model performance on nested subsets using the two provided evaluation protocols.
• Analyzing the sensitivity of climate outcomes to variations in the eight specified planetary characteristics.

Strengths

• Contains 1,760 distinct climate simulations, providing a substantial corpus for model training and evaluation.
• Simulations span 5 different General Circulation Models (GCMs), allowing for model intercomparison.
• Outputs are provided on a structured 32 x 64 latitude-longitude grid, facilitating spatial analysis.
• Includes three nested benchmark subsets and two evaluation protocols for standardized testing.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
• Description metadata is limited; actual data quality and file formats require manual inspection after download.
