- 02Bias-correct against ground stations (SLF / Météo-France nivôse).
- 03Build per-week climatological percentile · 30 winters.
- 04Anomaly = current week vs. cell's own 30-year baseline.
- 05Snow-sure read at the highest-snow cell within ~15km. When most resorts are bare, ranking shifts toward this, surfacing glaciers in shoulder seasons.
