April 2025 monthly summary for GEOSadas and GEOSgcm_App. Focused on data-management reliability, configuration correctness, and maintainability through packaging standardization, flag handling fixes, dependency upgrades, and land-DA workflow simplification.

March 2025: GEOSadas delivered targeted data handling and configuration improvements, and reduced data footprint in LFO collection. These efforts enhance reliability, configurability, and efficiency for GEOSdas simulations.

February 2025 (GEOS-ESM/GEOSadas): Implemented archival enhancements to improve data accessibility and long-term storage for ensemble data. Key deliverables include BKGLFORST archive support in gen_silo_arc.pl and extensive NCEP ensemble archiving improvements for LADAS/LFO, with configuration updates across related scripts. No major bug fixes were reported this month. Impact: faster, more reliable archiving pipeline, enabling downstream modeling and analyses with improved data availability and integrity. Skills demonstrated: Perl scripting for archival tooling, tar-based formats, cross-module configuration, version-controlled code changes, and collaboration with NCEP ensemble workflow teams.

January 2025 (2025-01) monthly summary for GEOSadas. Key feature delivered: Land Data Assimilation System (LDAS) integration into the GEOS-ADAS workflow, enabling end-to-end LDAS analysis by orchestrating predictor forcing files, feedback mechanisms, proper directory creation, and resource copying within the GEOSadas workflow.
