Reproducibility archive for "A geodetic ocean-mediated covariance bridge between length-of-day variability, ocean heat content, and global surface temperature"

This archive contains the data, code, institutional-source manifests, source snapshots, derived CSV files, manuscript-facing tables and figures, and supplementary validation materials needed to reproduce the results of the manuscript “A geodetic ocean-mediated covariance bridge between length-of-day variability, ocean heat content, and global surface temperature”. The archive supports exact replication of the annual and quarterly LOD-OHC-GMST bridge workflow, annual out-of-sample stress tests, IERS/GFZ AAM/OAM/HAM residualization, exploratory NASA LIS/OTD lightning context checks, appendix-specific reproducibility materials, MATLAB companion verification packages, and a no-code Excel/CSV audit route. The package supports exact replication from bundled institutional-source snapshots and an optional live-source rebuild from documented institutional endpoints. The manuscript files are submitted separately through the journal submission system. Some internal filenames, folder names, or notes may preserve legacy labels from earlier manuscript-preparation workflows for reproducibility stability. These labels do not indicate a different dataset or a different scientific version of the work; the archived materials correspond to the submitted manuscript and support the reproducibility claims described above.
