# Final Step forecasting on Transient ISSM ice-sheet simulation steps 61-240 (full rollout) Source: [Final Step forecasting on Transient ISSM ice-sheet simulation steps 61-240 (full rollout)]() Collection index: [llms.txt]() Data updated: 2026-06-11T09:05:56.853Z Evaluation of models performing final step forecasting on the full rollout of the Transient ISSM ice-sheet simulation (steps 61-240), measured using RMSE for velocity components (Vx, Vy), thickness, and an aggregated score. 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 | Final Step forecasting | | Dataset (including any stated split) | Transient ISSM ice-sheet simulation steps 61-240 (full rollout) | | Metric | Vx RMSE | | Unit | SCALAR | | Direction | Lower is better | | Results loaded | 6 of 6 | | 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 - [Vx RMSE](): Lower is better; unit: SCALAR. - [Vy RMSE](): Lower is better; unit: SCALAR. - [Thickness RMSE](): Lower is better; unit: SCALAR. - [Aggregated RMSE](): Lower is better; unit: SCALAR. ## Recorded results | Method | Vx RMSE | Result date | Report paper | | --- | --- | --- | --- | | Initial-state-conditioned baseline | 46.77 | Not recorded | 6a28f35f90966ade919c18c7 | | Multi-Horizon Emulator | 57.03 | Not recorded | 6a28f35f90966ade919c18c7 | | COGENT | 71.14 | Not recorded | 6a28f35f90966ade919c18c7 | | Multi-Horizon Emulator | 73.22 | Not recorded | 6a28f35f90966ade919c18c7 | | COGENT | 78.01 | Not recorded | 6a28f35f90966ade919c18c7 | | Single Step Autoregressive Model | 105.95 | Not recorded | 6a28f35f90966ade919c18c7 | ### Initial-state-conditioned baseline Vx RMSE: 46.77.
