January 2026 (2026-01) — NOAA-EMC/GDASApp: Implemented SMAP Soil Moisture Data Configuration for the JEDI Land Offline System. This work adds configuration files to enable SMAP soil moisture data integration into the JEDI land offline workflow, improving soil moisture assimilation accuracy and repeatability in offline experiments. The change is tracked in commit 5fa85ef27d16ccc3e42adce7b54fb52387b05944 with message 'Add smap soil moisture config files to jcb-gdas (#2011)'.

December 2025: NOAA-EMC/jcb-gdas delivered a new SMAP Soil Moisture Data Configuration to strengthen the JEDI workflow. Implemented configuration files specifying soil moisture variables and their handling in the model, enabling improved soil moisture analysis and forecasting within the data assimilation pipeline. This work was anchored by commit 1878e5d847026f5e1db25408fcebc25682cab352 ('Add smap soil moisture config files (#218)'). No major bugs reported this month. Overall impact includes higher forecasting reliability for soil moisture applications, reduced manual configuration overhead, and better reproducibility of the JEDI workflow. Technologies demonstrated include data assimilation workflows, configuration management, SMAP data handling, and Git versioning.

November 2025 monthly summary for TerrenceMcGuinness-NOAA/global-workflow: Delivered integration of soil data assimilation (DA) increments into the Gaussian surface analysis with land Incremental Analysis Updates (IAU) enabled. Updated configuration and scripts to re-grid soil increments on the FV3 grid, resolved file naming conflicts, and ensured proper archiving of soil increments. These changes improve the accuracy and consistency of surface analysis variables across cycles and lay the groundwork for more reliable DA-driven initial conditions.

Month 2025-09 - Key engineering work focused on data integrity for snow increment calculations and CI efficiency improvements across two NOAA-relevant repos. Delivered targeted fixes and CI optimizations that enhance data consistency, reduce feedback loops, and improve overall validation throughput.

Monthly summary for 2025-08: Implemented a critical bug fix in TerrenceMcGuinness-NOAA/global-workflow to improve warm-start soil increment archiving and staging. The changes correct configuration flag usage to accurately identify and archive the proper soil increment files, adds staging of increment files for cycled warm starts, and introduces a CI test case that covers warm-start scenarios to prevent regressions. This work strengthens data integrity, reliability, and reproducibility of warm-start runs, reducing end-to-end failures in production pipelines. Technologies demonstrated include config management, CI/test automation, and robust archiving pipelines.

July 2025: Focused on extending the archive workflow to include GSI Soil DA increments in TerrenceMcGuinness-NOAA/global-workflow. Delivered a feature that archives GSI Soil DA increment files by updating YAML archive_tars lists and adding a new Python configuration variable to enable/position these files in the archive. No major bugs fixed this month; the work improves data provenance, archival completeness, and reproducibility, enabling reliable downstream analytics. This aligns with business goals of data integrity and operational efficiency. Key technologies demonstrated include YAML configuration, Python scripting, and robust change-tracking via Git commits.

June 2025 monthly summary for TerrenceMcGuinness-NOAA/global-workflow. Focused on delivering scalable processing improvements and higher temporal fidelity in GDAS snow analysis and NOAHMP land data assimilation. No explicit bug fixes recorded this month; work centered on feature delivery and configuration enhancements to enable larger HPC runs and more timely analyses.

May 2025 performance summary for NOAA-EMC/GDASApp focusing on delivering key features, fixing critical issues, and driving overall impact. Highlights include enhanced land-jediincr namelist configuration with support for variable ensemble sizing and deterministic vs ensemble snow increments, along with a critical GFSv17 compatibility fix that corrected submodule URL handling and ensured proper frac_grid namelist configuration when the GFSv17 flag is enabled. Tests were updated to cover new parameters and configurations, improving reliability and maintainability of the snow increment workflow.
