Alfie focused on developing thick fog presence diagnostics for the MetOffice/CSET repository, delivering a feature that detects and reports fog events where visibility is less than or equal to 100 meters. He implemented new configuration files and diagnostic recipes using Python, YAML, and Shell, enabling domain mean time series analysis, spatial plotting, and spatial difference calculations. Alfie updated Rose workflow metadata and documentation to standardize fog reporting and support operational readiness. His work emphasized configuration management and data analysis, resulting in a robust, repeatable process for winter fog diagnostics that enhances forecast decision support and improves reporting quality.

Month: 2025-10 – Focused on delivering Thick Fog Presence diagnostics for MetOffice/CSET, establishing a robust capability to detect fog events and visualize/report them. The feature defines thick fog as visibility <= 100 m and includes configuration updates for domain_mean_time_series, spatial plots, and spatial differences, along with updated documentation to standardize fog reporting. No major bugs fixed this period; maintenance concentrated on diagnostics metadata and recipes to support repeatable winter fog reporting and operational readiness. This work enhances forecast decision support and reporting quality for fog-related events.
