Joe Stassi contributed to the GEOS-ESM/GEOSgcm_App and GEOS-ESM/GEOSadas repositories by building and refining configuration and job scheduling systems for atmospheric modeling workflows. He introduced dynamic LDAS increment configuration through template parameterization, enabling runtime tuning and reducing manual intervention. In GEOSadas, Joe enhanced deployment portability and reliability by propagating NODEFLG settings, adding resource constraint directives, and improving script compatibility with SLES-15. He addressed file handling bugs affecting LFO LDAS output, ensuring workflow stability and maintainability. His work demonstrated depth in Perl and shell scripting, configuration management, and system administration, with careful attention to integration and code clarity.

June 2025 monthly summary for GEOSadas focused on stabilizing LFO LDAS output through targeted bug fixes and maintenance work. The work preserved output integrity, reduced risk of tag breakages, and improved maintainability of file handling and related scripts.

March 2025 delivered targeted improvements to GEOSadas focused on configurability, reliability, and portability of deployment and monthly processing workflows. Notable features and bug fixes include: (1) FVDAS NODEFLG support across the FVDAS Run Config, integration into monthly job constraints, and related SLES-15 brace issue fixes to improve configurability and reliability of FVDAS runs; (2) addition of a constraint directive to the monthly_means job script template to allow explicit resource specification for monthly processing; (3) portable scripting enhancements with dynamic ESMABIN path derivation and a direct checkinput invocation from runjob.pl to increase usability and resilience; (4) Perl brace fixes across scripts for SLES-15 compatibility (including testsuites/checkinput.pl and write_monthly_rc_arc.pl) with updated usage/docs for multiple input files where applicable.

February 2025: Focused on delivering configurability improvements for the AGCM LDAS component within GEOSgcm_App. Implemented a dynamic LDAS increment configuration by introducing the @LDAS_INCR parameter and wiring it to a template variable, enabling runtime tuning of LDAS increments.
