196-year tree-ring chronology from the Kheygiyakha River region in Russia, covering the period from 156 to -40 calendar years before present. The dataset contains parameters for dendrochronological analysis and was archived by NOAA's World Data Service for Paleoclimatology. It was last updated in the NOAA NCEI system in January 1990.
Use Cases
- Reconstruct past climate variables like temperature or precipitation using the tree-ring width or density parameters.
- Calibrate radiocarbon dating or other chronological models by aligning the tree-ring chronology with known historical periods.
- Analyze long-term environmental stress events recorded in the tree-ring series for the specified geographic location.
- Compare this Siberian tree-ring series with other chronologies to study spatial patterns of past climate anomalies.
Strengths
- Covers a 196-year period (156 to -40 BP), providing a multi-century climate proxy record.
- Archived and maintained by the authoritative NOAA World Data Service for Paleoclimatology.
- Includes specific geographic location data for contextual analysis.
Limitations
- Temporal coverage ends at -40 BP (40 years before 1950), limiting direct overlap with the modern instrumental record.
- The dataset was last updated in 1990, indicating potential staleness in metadata or availability formats.
- Specific sample depth, measurement parameters, and potential measurement noise are not detailed in the provided description.
