AI Training Datasets
====================

The E3SM project and `Allen Institute for AI (Ai2) <https://allenai.org/>`_ work together to develop datasets for AI and machine learning applications. E3SMv2 and E3SMv3 have been processed by Ai2 to make them publicly accessible and easier to use for research purposes.

Dataset Details
***************

- **E3SMv2**: 73-year EAMv2 simulation (F2010, perpetual 2010 forcing, repeating annual SST cycle from 2005-2014 average). 6-hourly outputs: 42 years training, 10 years validation, 10 years test. More details see: `Duncan et al. 2024 <https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2024JH000136>`_

- **E3SMv3**: 51-year EAMv3 AMIP-style simulation (1970-2020, F2010 with AMIP SSTs, constant 2010 CO2). Includes multiple ENSO cycles and global warming trend. More details see: `Wu et al. 2025 <https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2025JH000774>`_

- **SCREAMv1**: Simple Cloud-Resolving E3SM Atmosphere Model version 1 training data (coming soon)
