During June 2025, Luc Andre developed and integrated new Icefall and Freezing Rainfall variables into the GEOS Lake Grid Component within the GEOS-ESM/GEOSgcm_GridComp repository. Using Fortran and leveraging expertise in climate modeling and scientific computing, Luc updated the surface energy and water balance calculations to account for these variables, improving the physical realism of lake-atmosphere interactions. The work included standardizing the icefall data short-name for consistency and applying minor fixes to ensure data stability during integration. This feature-focused effort laid the foundation for more accurate downstream energy budget analyses and enhanced coupling in numerical weather prediction workflows.

June 2025 monthly summary focusing on key accomplishments for GEOSgcm_GridComp. Delivered a major feature: integration of Icefall and Freezing Rainfall variables into the GEOS Lake Grid Component, with corresponding updates to surface energy and water balance calculations. Standardized the icefall data short-name to ICE for consistent lake-model representation. Applied minor fixes to FRZR and ICEF during integration to stabilize the feature and improve data consistency. No major bugs fixed this month; emphasis on feature delivery, code quality, and alignment with downstream modeling workflows.
