October 2025 (2025-10) – Expanded compute resource options by enabling Noaacloud environment support for data assimilation (DA) tasks in the TerrenceMcGuinness-NOAA/global-workflow repository. Implemented noaacloud as a valid machine ID for the ufsda case in load_modules.sh via a concise single-line case statement, enabling DA task execution on the noaacloud environment. This reduces resource contention and improves scalability for cloud-based DA workflows. No major bugs fixed this month; no regressions detected. Overall impact: increased flexibility and efficiency in DA task provisioning, supporting faster experimentation and deployment in cloud environments. Technologies and skills demonstrated: shell scripting (bash), environment orchestration, minimal-risk code changes, repository tooling, and cloud-enabled workflow integration.

September 2025 monthly summary for TerrenceMcGuinness-NOAA/global-workflow focused on cloud deployment and environment porting for tracker and genesis tasks. Delivered cloud-ready workflow components with direct WGRIB2 loading and syndat data staging, enabling scalable, reproducible runs in the noaacloud environment. Minor post-port testing issues were resolved promptly to ensure stability across cloud deployments.

August 2025 focused on stabilizing the UPP job environment and optimizing deployment configurations for the global-workflow. The UPP environment variable issue was fixed by adjusting the AWS env handling in the upp step, and the AWS deployment configuration enhancements were implemented to optimize resources for prep, fcst, anal, upp, and new enkfgdas, aligning with MPI cloud-best practices. These changes improve reliability, scalability, and cost efficiency across the workflow.

2025-07 monthly summary: Delivered cloud environment modernization for NOAA-EMC/GDASApp by upgrading Spack-Stack and refreshing dependencies. Aligned compiler environment with the newer stack to ensure compatibility, reproducibility, and access to updated software components for the GDAS application. These changes reduce build fragility in cloud environments and enable smoother CI/testing workflows.

June 2025 – TerrenceMcGuinness-NOAA/global-workflow: reliability and cost-efficiency enhancements for cloud workflows. Delivered a conditional chgrp rstprod execution fix and AWS runtime configurations for C96_atm3DVar to optimize resource usage. These changes reduce cloud run failures, lower compute costs, and improve throughput for analysis steps (anal, analcalc).

In May 2025, delivered cloud readiness for NOAA cloud in TerrenceMcGuinness-NOAA/global-workflow by updating AWS defaults for obs preprocessing on cloud, adjusting data paths, restricted-product handling, and NSST buffer creation to enable cloud-based processing. Also added Fit2Obs to NOAA cloud module environment by updating modulefiles/module_base.noaacloud.lua and adjusting module paths to ensure loadability. These changes enable scalable, cloud-native observation data processing, reduce cloud deployment setup time, and improve operational reliability for NOAA workflows.
