Yamal Polar Timberline Tree Ring Chronology from 415 to -13 BP

NOAA NCEI archives this paleoclimatology dataset containing tree-ring parameters from the Yamal Hadyta River polar timberline in Russia. The data provides a time-series chronology covering 428 years, from 415 to -13 calendar years before present. It is part of the NOAA World Data Service for Paleoclimatology and was archived in 1963.

Use Cases

• Reconstruct past temperature or precipitation anomalies using tree-ring width or density parameters as climate proxies.
• Analyze the response of polar timberline ecosystems to climate forcing over a 428-year period using the dated chronology.
• Calibrate radiocarbon dating or other chronological models with the precisely dated tree-ring series.
• Study extreme climatic events or periods of stress recorded in the tree-ring parameters for the Yamal region.

Strengths

• Time-series spans 428 calendar years, providing a multi-century climate record.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.

Limitations

• The dataset's last known update was in 1963, making it temporally stale for contemporary analysis methods.
• Specific parameters, sample size, and measurement methods are unknown without accessing detailed metadata.
