Kotuykan River Tree Ring Chronology For Paleoclimate Analysis

NOAA/WDS Paleoclimatology archives a tree ring dataset from the Kotuykan River B site in Russia. The data provides a climate proxy record spanning 427 years, from 387 to -40 calendar years before present. NOAA National Centers for Environmental Information (NCEI) maintains this archived study, last updated in 1990.

Use Cases

• Reconstruct past temperature or precipitation anomalies using tree ring width measurements as a proxy.
• Calibrate climate models by comparing the tree ring chronology against known historical climate events.
• Analyze growth patterns and climate sensitivity for tree species at the Kotuykan River site.
• Extend instrumental climate records further into the past using the 427-year tree ring time series.

Strengths

• Covers a 427-year time period (387 to -40 BP) for long-term trend analysis.
• Archived and maintained by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Data recency is low, with a last update date of 1990, potentially missing modern analytical methods.
• Geographic scope is limited to a single site (Kotuykan River B, Russia), reducing regional generalizability.
• Specific sample depth (row count) and measurement parameters are unknown from provided metadata.
