A non-intrusive machine learning framework for debiasing long-time coarse resolution climate simulations and quantifying rare events statistics

no code implementations28 Feb 2024 Benedikt Barthel Sorensen, Alexis Charalampopoulos, Shixuan Zhang, Bryce Harrop, Ruby Leung, Themistoklis Sapsis

To overcome this challenge, we introduce a dynamical systems approach where the correction operator is trained using reference data and a coarse model simulation nudged towards that reference.

Learning bias corrections for climate models using deep neural operators

no code implementations7 Feb 2023 Aniruddha Bora, Khemraj Shukla, Shixuan Zhang, Bryce Harrop, Ruby Leung, George Em Karniadakis

In this study, we replace the bias correction process with a surrogate model based on the Deep Operator Network (DeepONet).

Quantifying and attributing time step sensitivities in present-day climate simulations conducted with EAMv1

no code implementations15 Oct 2020 Hui Wan, Shixuan Zhang, Philip J. Rasch, Vincent E. Larson, Xubin Zeng, Huiping Yan

This study assesses the relative importance of time integration error in present-day climate simulations conducted with the atmosphere component of the Energy Exascale Earth System Model version 1 (EAMv1) at 1-degree horizontal resolution.
