Jul 1, 2026Month: 2026-07 — Delivered the Air Density Calculation feature for metoppv/improver, enabling density computations with support for both pressure and height levels. The work included a new notebook, extensive unit tests, and comprehensive documentation, achieving 100% test coverage. Implemented level-agnostic code changes, added calculation for specific humidity, and performed a series of maintenance improvements (ruff-linting, tidy-ups, and a refactor). Addressed test stability by fixing air density tests and updating condensate handling; performed coordinate-name fixes and removed an obsolete test notebook. Coordinated across teams with co-authored contributions from Mo-DavidJohnJohnston and Katherine Tomkins. Business value: improves accuracy and reliability of atmospheric analyses, reduces downstream modeling errors, and enhances developer productivity through robust tests and clear documentation.
