Joe Stassi contributed to the GEOS-ESM/GEOSgcm_App and GEOS-ESM/GEOSadas repositories by building and refining configuration management and job scheduling features. He implemented dynamic LDAS increment configuration using Jinja templating and Shell scripting, enabling runtime tuning and reducing manual intervention. In GEOSadas, Joe enhanced workflow reliability by propagating NODEFLG parameters, adding resource constraint directives, and improving script portability with Perl and Shell. He also addressed SLES-15 compatibility issues and stabilized LFO LDAS output through targeted bug fixes and code maintenance. Joe’s work demonstrated depth in scripting, environment variable management, and system administration, resulting in more robust, maintainable workflows.
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.
