PROFILE
Heiko Klein
Contributed to the metno/pyaerocom repository by delivering targeted improvements in configuration management, data handling, and project governance over a four-month period. Addressed model-specific plot type configuration issues in Python, ensuring stable reporting outputs and reducing duplication across model versions. Enhanced ungridded data integrity by refining data appending and altitude handling logic, minimizing risks of data loss in downstream analysis. Led a development release version bump using TOML to align release metadata with new development cycles. Improved UI clarity by enabling EBAS station codes as display names and strengthened repository maintainability through the addition of CI/CD workflows, documentation updates, and standardized templates.
