Tree-ring width measurements from Sakha, Russia, used for paleoclimate reconstruction. The chronology covers 434 years, from 378 to 44 calendar years before present. Data is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1994.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing annual tree-ring width variations.
- Calibrate climate models using the 434-year proxy record from a high-latitude boreal forest site.
- Study long-term environmental stress events in the Sakha region through anomalies in the ring-width series.
- Perform cross-dating with other regional chronologies using the shared time-series data.
Strengths
- Covers a 434-year time period (378 to 44 BCE), providing a multi-century climate proxy.
- Sourced from NOAA's authoritative World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends 44 BCE, limiting analysis of recent climate trends.
- Data is geographically limited to a single site in Sakha, Russia.
- The dataset's last documented update was in 1994, indicating potential staleness.
