Reproducibility archive for empirical covariance linking geomagnetic variability, Earth rotation, ocean heat content, and global temperature (1981-2024)

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 “Empirical covariance linking geomagnetic variability, Earth rotation, ocean heat content, and global temperature (1981-2024): annual bridge evidence and quarterly validation”. The archive includes the main annual and quarterly bridge workflow, annual out-of-sample stress tests, IERS/GFZ AAM/OAM/HAM residualization, the exploratory NASA LIS/OTD lightning context layer, appendix-specific reproducibility materials, MATLAB companion verification packages, and a no-code Excel/CSV audit pack. The package supports exact replication from bundled institutional-source snapshots and an optional live-source rebuild from documented institutional endpoints.
