PROFILE
Carol Halliwell
Carol Halliwell contributed to the MetOffice/CSET repository by developing and refining backend workflows for atmospheric data analysis. Over four months, she implemented grid-aware data extraction, enhanced power spectrum calculation and visualization, and improved usability in regridding workflows. Her work involved restructuring Python code for maintainability, introducing robust coordinate system handling, and expanding unit test coverage to ensure reliability. Carol also addressed technical debt by deprecating legacy features and updating documentation for clarity. Using Python, YAML, and Cylc, she focused on data validation, workflow automation, and scientific computing, delivering solutions that improved data provenance, reduced misconfiguration risk, and supported downstream analytics.

3 Commits • 1 Features
Nov 1, 2025November 2025 (MetOffice/CSET): Delivered a significant API-driven refactor of the power spectrum calculation, including function restructuring, stronger cube-dimension validation, debugging logs, and updated documentation. The test suite was aligned with the new API, with test updates to reflect _DCT_ps and _create_alpha_matrix. Commit history shows targeted responses to code-review feedback and clean test-name migrations. Overall, this work improves reliability and maintainability for downstream analytics, enabling faster iteration and clearer failure modes. Technologies demonstrated include Python, pytest, logging, and documentation tooling.
