PROFILE
Erin Thomas
Ethan Thomas contributed to the E3SM-Project/E3SM repository by developing and refining features for climate and ocean modeling, focusing on robust configuration and model coupling. He implemented conditional wave-ocean coupling and standardized user-facing configuration, reducing unnecessary data transfers and improving simulation reliability. Using Fortran, Python, and shell scripting, Ethan enhanced code maintainability through systematic refactoring, code cleanup, and test infrastructure improvements. He addressed critical bugs, such as correcting Langmuir mixing logic under icy conditions, and improved build system configuration. Ethan’s work demonstrated depth in scientific computing and high-performance environments, resulting in more stable, reproducible, and maintainable simulation workflows.

Feb 1, 2025February 2025 monthly summary for E3SM: Implemented Coupling Mode Naming Standardization to unify user-facing configuration and improve simulation reliability. Commit fbfba72651b9de7e1b7c925fd891b01c038413b8 redefines wav_ocn_coup as 'oneway' or 'twoway'. This standardization reduces configuration errors and strengthens reproducibility across simulations. No major bugs recorded this period; efforts concentrated on naming standardization, refactoring, and configuration governance. Overall impact includes smoother user experience, improved automation, and a stronger foundation for CI testing. Technologies/skills demonstrated include Git version control, code refactoring for naming conventions, and cross-team collaboration.

Oct 1, 2024Month 2024-10: Delivered a critical bug fix and code-quality improvements to Langmuir mixing logic in the LandIce component under icy conditions. The work gated Langmuir computations by land-ice mask and ice fraction thresholds, and refined model selection based on configuration flags to prevent erroneous calculations. Resulting in more accurate and stable LandIce simulations in cold scenarios, with clear traceability to the commit below.
