Temperature signal instability of tree-ring width chronologies from the upper treelines in the Qaidam Basin, northeastern Tibetan Plateau

Puntos clave

• Temperature signal instability impacts tree-ring width chronologies, affecting climate interpretations.
• Key measurements demonstrate a significant correlation between temperature fluctuations and tree-ring growth variability.
• Analysis of tree-ring data from upper treelines reveals structural changes over the growing seasons.
• Understanding these variations supports better climate modeling, indicating potential environmental changes.
