ClimSim: A large multi-scale dataset for hybrid physics-ML climate emulation
Published in NeurIPS 2023 Datasets and Benchmarks Track, 2023
This paper establishes a comprehensive set of datasets and benchmarks for machine learned subgrid parameterizations of convection and radiation in E3SM-MMF. It received the Outstanding Paper award for the Datasets and Benchmarks track at NeurIPS 2023.

Stress-testing the coupled behavior of hybrid physics-machine learning climate simulations on an unseen, warmer climate
Published in NeurIPS 2023 Climate Change AI Workshop, 2023
This paper samples the coupled behavior of neural network convective parameterizations at scale on an unseen, warmer climate to see if design decisions conducive to better online performance in-distribution do the same out-of-distribution.

Stable Machine-Learning Parameterization of Subgrid Processes in a Comprehensive Atmospheric Model Learned From Embedded Convection-Permitting Simulations
Published in Journal of Advances in Modeling Earth Systems (JAMES), 2025
Building off ClimSim, this paper is the first to yield a stable and accurate machine-learning parameterization of subgrid processes (including explicit cloud condensate coupling) in a comprehensive atmospheric model learned from embedded convection-permitting simulations.

Crowdsourcing the Frontier: Advancing Hybrid Physics-ML Climate Simulation via a $50,000 Kaggle Competition
Published in Journal of Advances in Modeling Earth Systems (JAMES) (in review), 2025
This paper takes ideas from the winning teams of the 2024 LEAP ClimSim Kaggle competition and systematically tests them offline and online to reveal SOTA performance, universal failure modes, and architecture-dependent idiosyncracies.
