Yakutsk Tree Ring Chronology from 220 to 41 BCE

261-year tree ring chronology from 220 to 41 BCE, providing a proxy record for past climate conditions. The dataset is part of the NOAA/WDS Paleoclimatology archive, contributed by Schweingruber from the Yakutsk Biological Station. It was last updated in the NOAA system in 1991.

Use Cases

• Calibrating climate models by correlating tree ring width measurements with temperature and precipitation proxies.
• Reconstructing past drought events by analyzing the annual resolution of the ring chronology.
• Studying ecological responses to historical climate shifts using the dated tree ring series.
• Cross-dating and validating other paleoclimate archives from the Siberian region using this master chronology.

Strengths

• Covers a continuous 261-year period from 220 to 41 BCE.
• Sourced from the authoritative NOAA World Data Service for Paleoclimatology.
• Provides annual-resolution data for high-precision climate analysis.

Limitations

• Data is temporally stale, with a last recorded update in 1991.
• Geographic coverage is limited to a single biological station in Yakutsk, Russia.
• Specific parameters like ring width measurements are not detailed in the provided metadata.
