February 2026 monthly summary for CliMA/ClimaOcean.jl: Delivered a critical bug fix addressing geographic coordinate handling and depth averaging, improving data accuracy and downstream model reliability.

Monthly summary for 2026-01 focusing on targeted enhancements across two CliMA repositories. Delivered a documentation accuracy improvement in Oceananigans.jl by correcting boundary conditions typos, and a numerical accuracy improvement in ClimaOcean.jl by refactoring the atmospheric state interpolation to use Center(), resulting in more reliable state estimates. Key deliverables across repositories: - Oceananigans.jl: Documentation typos related to boundary conditions corrected to improve user guidance (commit e31e005b26ac4e93d43e651f67a70601c33494ed). - ClimaOcean.jl: Atmospheric state interpolation accuracy enhanced by using Center() in Atmospheres.jl (commit c74f64bba273aa6d396ea4a0c74c5ac17520b9ae). Overall impact: Improved clarity for users and more accurate simulations, supporting better usability and research outcomes. Technologies/skills demonstrated: Julia, documentation best practices, refactoring for numerical accuracy, leveraging Center() for improved interpolation.

December 2025 summary: Delivered a distributed FFT preconditioner for the ConjugateGradientPoissonSolver in CliMA/Oceananigans.jl, including refactored pressure correction calculations, new methods, and clearer documentation to enable scalable Poisson solves on distributed memory. Fixed hydrostatic pressure anomaly default for vertically periodic grids and added targeted tests to ensure correct behavior. Corrected API documentation for the target function signature to include the additional parameter t, with tests validating the docs. These changes improve numerical performance and scalability, ensure correctness in edge topologies, and enhance developer experience through better docs and tests.
