Jennifer Brooke developed the Snow Presence Diagnostic for the MetOffice/CSET repository, delivering a Winter Weather-aware diagnostic tool with spatial and temporal plotting capabilities. She implemented Python-based data analysis pipelines and refined configuration management using YAML and .conf files, enabling more reliable deployment and clearer configuration structures. Her work included updating categorization schemes, integrating reviewer feedback, and resolving merge conflicts between snow and fog diagnostics to improve code stability. By enhancing plotting recipes and domain-mean time series analysis, Jennifer provided scalable, evidence-based insights into winter conditions, demonstrating depth in climate science, configuration management, and Python development within a focused project scope.

October 2025 delivered the Snow Presence Diagnostic for MetOffice/CSET, introducing Winter Weather-aware diagnostics with plotting capabilities (spatial plot, spatial difference plot, and domain-mean time series) and refined categorization. Config updates included sorting keys, loader/config refinements, and integration with .conf exchanges. Responded to reviewer feedback by updating recipes and evolving from Daily Weather to Winter Weather. Resolved merge conflicts between the snow and fog diagnostics, improving stability and maintainability.
