Kotuy River Tree Ring Chronology from 320 to 40 BC

Tree ring width measurements from the Kotuy River region in Russia provide a 360-year climate proxy record. The data was archived by the NOAA National Centers for Environmental Information under its Paleoclimatology program. This specific chronology was last updated in the repository in 1990.

Use Cases

• Reconstruct summer temperature anomalies for Arctic Siberia using the tree ring width series.
• Calibrate the tree ring chronology against instrumental records to validate its climate signal.
• Analyze growth trends and extreme narrow rings to identify volcanic or climatic events during the covered period.
• Compare the Kotuy River chronology with other ITRDB series to assess spatial climate patterns.

Strengths

• Covers a continuous 360-year period from 320 to 40 BC.
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection curated by NOAA NCEI.

Limitations

• The chronology ends over 2000 years ago, limiting direct comparison to modern instrumental data.
• Sample depth (number of trees/cores) and replication statistics are unknown from the provided metadata.
• Data is from a single geographic site, which may not represent regional climate conditions.
