Processed data and reproducibility outputs for: The South Atlantic–SACZ Pathway Shapes ENSO Phase Selection under Neutral Initial Conditions and Is Gated by Pacific Subsurface State

Processed data and reproducibility outputs for the manuscript "The South Atlantic–SACZ Pathway Shapes ENSO Phase Selection under Neutral Initial Conditions and Is Gated by Pacific Subsurface State" by Fabio Bellacanzone, Simona Bordoni, and Theodore G. Shepherd (submitted to Journal of Geophysical Research: Atmospheres). The archive contains the processed 1979–2025 time series, event labels, summary tables, causal-graph provenance, cohort metadata, and the figure outputs used in the manuscript and Supporting Information. Raw HadISST, ERA5, and ORAS5 files are not redistributed: ERA5 and ORAS5 are available from the Copernicus Climate Data Store, and HadISST from the Met Office Hadley Centre. The analysis software is archived separately (10.5281/zenodo.22165958).
