Worked on enhancing the GEOS-Chem model documentation within the ige-calcul/public-docs repository, focusing on improving clarity and accuracy for both internal teams and external users. Updated key documentation files using Markdown, specifically refining modeling-systems.md and geos-chem.md to better reflect current model functionality and clarify team responsibilities. Emphasized content management and documentation best practices to streamline onboarding and reduce support needs. No major feature deployments or bug fixes were introduced beyond these documentation improvements. The work prioritized maintainability and alignment with evolving project capabilities, ensuring that technical information remains accessible and up to date for all stakeholders interacting with the repository.
