Archived forecast products: Complex-Wavelet Earthformer Forecasting of Tropical Pacific Sea Surface Temperature

Large binary artifacts underlying the paper "Complex-Wavelet Earthformer Forecasting of Tropical Pacific Sea Surface Temperature: Development-Period Skill and the Behavior of a Residual-Diffusion Ensemble" (submitted to Artificial Intelligence for the Earth Systems, 2026). Contents: deterministic model validation forecasts and scorecards; the canonical seed-42 raw 32-member residual-diffusion ensemble (47 validation windows, 14 leads, 2021-2025 target months); ten seed-replication ensembles; the spread-only EMOS/ECC-Q calibrator and coherently lifted member fields; trained checkpoints (deterministic transfer, ensemble transfer, CMIP6 forecast-pretraining backbone, CMIP6 sequence-diffusion head, and the ICAR-ENSO Earthformer base weights) with the frozen coefficient normalizer; and a SHA-256 manifest. All products are on a 24x48 tropical Pacific grid (30S-30N, 120E-280E), monthly cadence, in the relative-SST-anomaly frame defined in the paper. The training and evaluation pipeline, configuration files, reference scorecards, and reproduction instructions are in the companion GitHub repository linked under Related works.
