Developed the Snow Presence Diagnostic feature for the MetOffice/CSET repository, introducing Winter Weather-aware diagnostics with spatial and temporal plotting capabilities. Leveraged Python and YAML to implement spatial plots, spatial difference plots, and domain-mean time series, while refining configuration management through updates to loader logic and .conf exchanges. Addressed reviewer feedback by updating diagnostic recipes and evolving the categorization from Daily Weather to Winter Weather, ensuring alignment with project requirements. Resolved merge conflicts between snow and fog diagnostics, enhancing code stability and maintainability. The work improved winter-condition visibility and enabled scalable, evidence-based analysis for climate science applications.
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.
