Apr 1, 2025April 2025: Delivered a comprehensive STOFS-3D v7.2 pre-processing toolkit overhaul for schism, focusing on reliability, performance, and maintainability. Consolidated and upgraded sources/sinks tooling with bathymetry editing and file generation; refactored and modularized the ATL driver; added a sample usage workflow; strengthened input validation, subset workflow, UTF-8 handling, and robust error handling for source relocation and duplicates; performed codebase cleanup and updated the data processing flow. Added a new sample workflow for subsetting sources/sinks, improved gen_sourcesink_nwm integration (hgrid_fname input and returning the newly generated cache path), removed an outdated script, and completed targeted cleanup to reduce maintenance burden. Overall, these changes improve deployment readiness for v7.2 and reduce runtime risk. Note: No major bugs fixed this period; focus was on feature delivery and robustness.
