# Early Warning Signal Detection on HadISST AMOC 1870–2022 2° grid (historical observation) Source: [Early Warning Signal Detection on HadISST AMOC 1870–2022 2° grid (historical observation)]() Collection index: [llms.txt]() Data updated: 2026-06-17T07:11:24.665Z Evaluation of models for detecting early warning signals using historical oceanographic data from the HadISST AMOC dataset (1870–2022, 2° grid resolution). A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Early Warning Signal Detection | | Dataset (including any stated split) | HadISST AMOC 1870–2022 2° grid (historical observation) | | Metric | AUROC | | Unit | SCALAR | | Direction | Higher is better | | Results loaded | 4 of 4 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [AUROC](): Higher is better; unit: SCALAR. - [AUPRC](): Higher is better; unit: SCALAR. - [IoU](): Higher is better; unit: SCALAR. - [Lead Time (mo)](): Higher is better; unit: TIME. ## Recorded results | Method | AUROC | Result date | Report paper | | --- | --- | --- | --- | | ST-CND | 0.783 | Not recorded | 6a3229f7d33dfb23e783e9f9 | | Classical EWS | 0.681 | Not recorded | 6a3229f7d33dfb23e783e9f9 | | λ-AR1 | 0.596 | Not recorded | 6a3229f7d33dfb23e783e9f9 | | Recurrence-net | 0.5 | Not recorded | 6a3229f7d33dfb23e783e9f9 | ### ST-CND AUROC: 0.783.
