PROFILE
Katjaweigel
Over a three-month period, Weigel contributed to the ESMValGroup/ESMValTool repository by developing regional climate data analysis features and enhancing data export capabilities. He implemented new analysis recipes and YAML configurations for regional historical climate assessments, enabling robust cross-model comparisons aligned with IPCC regions. Using Python, NetCDF, and Seaborn, he added CF-compliant NetCDF export functionality for seaborn diagnostic plots, allowing underlying data to be saved for further analysis and sharing. Weigel also addressed a critical bug in benchmark metric identification, improving result reliability. His work demonstrated depth in climate data processing, configuration management, and reproducible scientific workflows.

Jul 1, 2025Month: 2025-07 – Delivered new regional climate data analysis capabilities in ESMValTool, enabling robust regional assessments for historical climate data. Implemented regional historical analysis recipes and configurations focused on annual cycles, time series, and linear trends; enhanced cross-model comparisons with reference datasets across defined IPCC regions; added YAML configuration files and updated documentation to improve usability and reproducibility. This work strengthens regional decision-support, accelerates reproducible analysis, and aligns with IPCC regional assessment needs. The changes are associated with REF updates (commit 3865eda97c47f113953e6e04080dbffcfd80acf6).
