Asia continental-scale tree-ring oxygen isoscape

Caption

Isoscapes illustrating the spatial distribution of tree-ring oxygen isotopes across Asia, generated using machine learning from 313 multi-year tree-ring records. The “sandwich” pattern features depleted values at high (>50°N) and low (<30°N) latitudes, and enriched values at mid-latitudes (30–50°N).
