June 2025 monthly summary for CliMA development. This period focused on extending simulation horizons and improving moist thermodynamics across two core repositories, CliMA/ClimaCoupler.jl and CliMA/ClimaAtmos.jl. Deliverables were achieved via YAML configuration changes and a physics implementation in the atmospheric model, with commits recorded for traceability.

May 2025 performance highlights across CliMAAtmos.jl, CliMA/RRTMGP.jl, and ClimaCore.jl focusing on reproducibility, standardized configurations, robust CI/testing, and maintainable releases. This work improves experiment reliability, reduces setup friction, and accelerates delivery of scientifically credible results.

April 2025 monthly performance summary focused on delivering robust physics improvements, strengthening release discipline, and ensuring ecosystem compatibility across two core CliMA repositories.

March 2025 highlights: Delivered Deep Atmosphere Simulation Support for CliMA/ClimaAtmos.jl, enabling deep_atmosphere configuration and extending the RRTMGP radiation model to spherical geometries, with targeted updates across the radiation stack and model interface.

February 2025: Delivered key features and bug fixes for CliMAAtmos.jl, focusing on enabling deep atmosphere dynamics by default, stabilizing important diagnostics, and improving reproducibility. This work enhances model fidelity, usability, and business value by providing accurate, out-of-the-box simulations and clearer governance of model configurations.

January 2025: CliMA/ClimaAtmos.jl delivered a new artifact configuration entry for DYAMOND_SUMMER_ICS_p14deg in Artifacts.toml, enabling reproducible builds and CI testing for a new test scenario. The change includes a git-tree-sha1 hash to ensure artifact integrity and traceability of the associated build. No major bugs were logged this month; focus was on configuration management, reproducibility, and CI readiness, setting the stage for expanded test coverage and more reliable releases. Technologies demonstrated include Artifacts.toml configuration, git-based traceability, and artifact metadata management within the Julia ecosystem.
