Developed a dynamic GSI Info File Generator for the TerrenceMcGuinness-NOAA/global-workflow repository, focusing on workflow automation and data assimilation reproducibility. Leveraged bash scripting and environment configuration to enable per-analysis-date generation of satellite, ozone, and conventional observation info files, introducing three new scripts for this purpose. The solution decoupled operational and reanalysis input data paths, allowing flexible, environment-controlled builds while maintaining conservative defaults. By updating configuration files and documentation, the work improved traceability, reduced manual intervention, and clarified data-path governance. This approach streamlined data processing workflows, enhanced maintainability, and supported more reliable, automated builds for both operational and reanalysis contexts.
