Sep 1, 2025September 2025 monthly summary for ACCESS-NRI/spack-packages focused on stabilizing UM model packaging and strengthening dependency management in Spack to deliver reliable, reproducible build environments for JULES/UM configurations. Implemented a critical bug fix to remove the -V flag from Fortran compiler flags, preventing interference with the Spack compiler wrapper and ensuring correct compilation. Performed a Spack packaging refactor to improve dependency handling by switching from tag-based variants to ref variants, adopting HTTPS for GitHub URLs, and updating compiler flags and source paths for vn13p1-am.

Jul 1, 2025July 2025 monthly summary for ACCESS-NRI/spack-packages. Focused on expanding the UM vn13p5-rns model data source coverage by adding new source configurations to improve performance and accuracy, aligned with the existing u-by395/nci_access_ram3 baseline for consistency. Delivered via a single commit that extends the model configuration (6154b74e33002c0a8ab2922a258386ee449941cc). This work enhances data ingestion, reduces data gaps, and supports more reliable model outputs. No major bugs fixed this month; stability improvements achieved through config validation and integration testing.
