Feb 1, 2025February 2025 monthly summary for metoppv/improver. Key feature delivered: Forecast data climatological anomalies computation, enabling conversion of forecast data into both unstandardized and standardized climatological anomalies. The implementation includes robust input validation for units, spatial coordinates, and time compatibility, and applies correct metadata (standard names, units, reference epochs, and cell methods) to the output cubes. This work strengthens climatology analysis capabilities, improves data quality, and supports more reliable downstream analytics.

Dec 1, 2024December 2024 — metoppv/improver: Delivered two targeted improvements to weather hazard calculations and strengthened test baselines. Key features: added a time-sum cell method along the time coordinate to correctly accumulate non-instantaneous data for freezing rain probability. Major bug fix: completed the LightningFromCapePrecip bug by adding the missing CellMethod, with acceptance tests and baseline updates. Impact: higher reliability and usefulness of freezing rain and lightning forecasts, supporting safer and more informed decision-making. Technologies/skills: Python data processing, coordinate-based accumulation, test/CI hygiene, contribution workflow (tests, checksums, CONTRIBUTING.md/.mailmap).
