Ayakli River Tree Ring Chronology From Eastern Russia

78 tree-ring width measurements from a site in Eastern Russia, extending from 78 to -40 calendar years before present. This dendrochronological dataset is archived by NOAA's World Data Service for Paleoclimatology. The data was last updated in the public record in 1990.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width time-series as a proxy.
• Calibrate the chronology against other regional tree-ring records using the reported calendar years BP.
• Analyze long-term environmental stress events in Eastern Russia from variations in the ring-width parameter.
• Validate climate model simulations for the last two millennia with this high-resolution proxy data.

Strengths

• Time-series covers a 118-year period, providing a snapshot of environmental conditions.
• Data is curated and archived by the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Very small temporal coverage (118 years) limits analysis of long-term climate trends.
• Data is geographically limited to a single site (Ayakli River B) in Russia, reducing regional representativeness.
• The record was last updated in 1990, indicating potential staleness and lack of recent methodological improvements.
