Altai Mountain Tree-Ring Chronology From 382 to -45 BP

NOAA/WDS Paleoclimatology archives a tree-ring chronology dataset from the Altai region of Russia. The data covers a 427-year period from 382 to -45 calendar years before present. NOAA National Centers for Environmental Information (NCEI) compiled and last updated this record in 1995.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing annual tree-ring width variations.
• Calibrate climate models for Central Asia using the 427-year proxy record from the Altai site.
• Study extreme climate events or volcanic impacts by identifying narrow ring sequences within the chronology.
• Perform cross-dating with other regional tree-ring series to validate the chronology's time axis.

Strengths

• Data spans a 427-year period (382 to -45 BP), providing a multi-century climate record.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at -45 BP, lacking recent centuries for modern climate comparison.
• Record is from a single geographic site (Russia, Altai), limiting regional representativeness.
• Last update was in 1995, indicating potential staleness in metadata or availability.
