Schweingruber Tree Ring Chronology From Uel-Siktjach River, Russia

NOAA/WDS Paleoclimatology archives a tree-ring chronology from the Uel-Siktjach river region in Russia. The dataset covers 296 years, from 256 to -40 calendar years before present, for paleoclimate reconstruction. NOAA National Centers for Environmental Information (NCEI) provides this archived study, last updated in 1990.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width index as a climate proxy.
• Calibrate the chronology against other regional datasets using its documented calendar year dating.
• Analyze growth patterns and extreme events within the 296-year time series for specific site conditions.

Strengths

• Covers a 296-year time series (256 to -40 BP), providing a multi-century climate record.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at -40 BP (approximately 1990 CE), lacking recent decades for modern comparison.
• Data is geographically limited to a single river site in Russia, limiting regional generalizability.
• The last documented update was in 1990, indicating potential staleness in metadata or curation.
