Evaluation of model infrastructure and training efficiency (Model Size, Training Time) for dense-to-dense, medium-range weather forecasting tasks utilizing the ERA5 reanalysis dataset spanning 1979 to 2015.

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 | Dense-to-dense, medium-range weather forecasting |
| Dataset (including any stated split) | ERA5 reanalysis 1979–2015 |
| Metric | Training Time (hours) |
| Unit | TIME |
| Direction | Lower is better |
| Results loaded | 1 of 1 |
| 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.
