Altai Mountain Tree Ring Chronology from 369 to 44 BC

NOAA/WDS Paleoclimatology archives a tree-ring chronology dataset from the Ust Koksa Hill site in Russia's Altai region. The data provides annual growth measurements covering a 413-year period from 369 to 44 calendar years before present. This study was contributed by Schweingruber and is managed by the NOAA National Centers for Environmental Information.

Use Cases

• Calibrating climate models by comparing tree-ring width variations against known historical climate events.
• Reconstructing past temperature or precipitation anomalies for the Altai region using annual growth measurements.
• Analyzing long-term ecological resilience by examining growth trends and stress events within the chronology.
• Dating archaeological or geological samples from the region through cross-dating with this master chronology.

Strengths

• 413-year continuous chronology from 369 to 44 BP provides a multi-century climate record.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.

Limitations

• Dataset is temporally stale, with a last update recorded in 1994.
• Geographic coverage is limited to a single site (Ust Koksa Hill) in the Altai.
