PROFILE
Carol Halliwell
Worked on the MetOffice/CSET repository to deliver robust backend features for scientific data processing and visualization. Developed grid-aware data extraction and power spectrum analysis workflows, implementing coordinate system selection and regridding for atmospheric datasets. Enhanced usability by introducing safer defaults and improving documentation, reducing misconfiguration risks and supporting developer onboarding. Refactored the power spectrum calculation API, adding stronger validation, debugging logs, and aligning the test suite for maintainability. Utilized Python, YAML, and Cylc to automate workflows, enforce data validation, and streamline testing. The work emphasized reliability, clear documentation, and test-driven development, enabling stable analytics and efficient downstream processing.

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.
