Over ten months, Hannes Humpenöder enhanced the pik-piam/piamInterfaces repository by developing and refining data mappings, scenario configurations, and reporting pipelines for land use, emissions, and agricultural datasets. He applied R and YAML to implement granular data models, improve version control, and align metadata across releases, ensuring traceable and reproducible analytics. His work included expanding support for peatland and wetland emissions, introducing new product categories, and standardizing unit mappings to improve data integrity. By focusing on configuration management, data modeling, and CI/CD practices, Hannes delivered robust, maintainable solutions that improved downstream analytics, reporting accuracy, and governance across the project.

2025-03 monthly summary: Delivered targeted improvements in emissions accounting and configuration management, enhancing data quality for policy analysis and expanding modeling flexibility while maintaining release discipline across two core repos. In pik-piam/piamInterfaces, accuracy of CO2 emissions reporting was improved by adding a residual emissions category and refining land-use change reporting, alongside standardizing emissions data naming and aligning package versioning for consistency. In remindmodel/remind, ScenarioMIP configuration was expanded to support multiple SSP scenarios, NDC targets, and new food scenario parameters, with additional updates to MAgPIE settings; a revert was performed to restore baseline stability for an NDC-related configuration. These efforts collectively improve decision-support analytics, reduce maintenance risk, and streamline release readiness.

February 2025 monthly summary: Deliverables across two repositories. In pik-piam/piamInterfaces, enhanced CO2/AFOLU carbon accounting mappings and land-use data categorization, including timber storage in harvested wood products, refined entries for carbon removal and gross emissions, expanded agricultural and livestock representations, and improved granularity of CO2 emissions reporting. In remindmodel/remind, updated MAgPIE scenario configuration to reflect revised plantation and NPi modeling assumptions. Release engineering: v0.44.3 metadata and versioning updates across build and docs, including a fix related to missing build. Major bugs fixed: none reported; minor build metadata issue resolved as part of the release. Overall impact: more accurate emissions accounting, better decision-ready reporting, and smoother release processes. Technologies/skills demonstrated: data modeling and mappings, configuration management, release engineering, and cross-repo collaboration.
