PROFILE

Joe Stassi

Worked on GEOS-ESM/GEOSgcm_App and GEOS-ESM/GEOSadas, delivering four features and two bug fixes over three months. Developed dynamic configuration capabilities for LDAS increments in AGCM by parameterizing templates with Jinja and Shell, enabling runtime tuning and reducing manual intervention. Enhanced GEOSadas by propagating NODEFLG settings, improving job scheduling, and adding explicit resource constraints to monthly processing scripts. Addressed SLES-15 compatibility through Perl scripting fixes and improved portability with dynamic environment variable handling. Stabilized LFO LDAS output by refining file handling and exclusion logic, maintaining workflow integrity and reducing regression risk. Demonstrated strengths in configuration management and scripting.

Mar 1, 2025

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.
