Returns one score matrix per location, models by evaluation metrics, for a single weather metric at a single lead time, plus the winning model per location. <br><b>When to use:</b> Answer 'which forecast model is most accurate here?' at scale — to map the best model by region, to check whether a specific model is worth using over the default blend, or to compare physical and AI models across the world. <br><b>Date format:</b> ymd_start and ym…
Forecast Skill by Lead Time — Scores how well each forecast model performed at ONE location, across several forecast lead times and across a sliding time window. Shows both how fast accuracy decays as the forecast reaches further ahead, and how accuracy at a given lead time has varied over recent weeks. <br><b>When to use:</b> Answer 'how far ahead can I trust the forecast here?' or 'has the forecast been unusually poor here lately?'
