Over four months, Schreyer enhanced the pik-piam/piamInterfaces and pik-piam/mrremind repositories by developing and refining data pipelines for climate and energy modeling. He improved carbon accounting and emissions mapping, integrating new variables and aligning data structures to support more granular scenario analysis. Using R, YAML, and dplyr, Schreyer engineered robust data ingestion and transformation workflows, addressed mapping inconsistencies, and implemented version control practices to ensure release readiness. His work included code refactoring for maintainability, documentation updates, and configuration management, resulting in higher data fidelity, improved reproducibility, and more reliable outputs for downstream climate policy and energy system analyses.

January 2025 performance summary for pik-piam/piamInterfaces: Focused on elevating data fidelity and consistency of carbon accounting mappings across ScenarioMIP and ARIADNE interfaces. Delivered targeted feature work to enhance waste-emissions mapping, introduced renaming rules for CDR and synthetic fuels, and aligned mappings with feedstock variables. Updated and stabilized the PIAM Interfaces library to ensure compatibility and accurate metadata. These efforts improve CO2 accounting accuracy for waste-related processes, enable more reliable scenario analysis, and support regulatory reporting.
