September 2025 monthly summary for GEOSgcm_GridComp focusing on ice–ocean interaction updates and configuration improvements.

July 2025 monthly summary for GEOSgcm_App. The primary delivery this month was automation to ensure correct sea-ice configuration propagation when cloning runs that use the CICE6 model. Specifically, the gcm_setup script now conditionally copies the ice_in configuration for CICE6 runs, controlled by sea-ice model detection, ensuring proper sea-ice settings are carried over to new runs. This reduces manual steps, improves reproducibility, and lowers the risk of misconfigurations in production workflows. Commit b21956c5ef410b58e8ba69de8513ff39e8b8fa46 documents the change. No major bugs fixed this month. The work demonstrates solid scripting, configuration management, and a strong understanding of the CICE6 workflow within GEOSgcm_App.

June 2025 monthly summary focusing on key accomplishments in GEOSgcm_App.

Month: 2025-05 – Focused on stabilizing restart workflows in GEOSgcm_App by introducing automatic alignment of restart_pond_lvl with pond restart data. This work reduces manual flag management, improves resilience of simulations when restart data is partially available, and contributes to more reliable long-running experiments. No major bugs fixed this month.

February 2025 monthly summary for GEOSgcm_GridComp: Delivered multi-resolution enhancements to the sea-ice model configuration, enabling more accurate and flexible simulations across grid setups.
