Sakha Tree Ring Chronology Spanning 472 Years

A 472-year tree-ring chronology from a site south of Chokurdak, Sakha Republic, Russia, covering the period from 428 to -44 calendar years before present. The dataset was archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. The data was last updated in the NOAA system in 1994.

Use Cases

• Reconstructing past temperature or precipitation anomalies using the tree-ring width series as a climate proxy.
• Calibrating the chronology against known climate events within its 472-year temporal coverage.
• Analyzing growth trends and extreme events recorded in the LAGM (Lakeside south of Chokurdak) tree-ring series.
• Comparing this ITRDB RUSS185 chronology with other Siberian records to assess regional climate patterns.

Strengths

• Chronology covers a substantial 472-year time period for climate analysis.
• Data is curated and archived by the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last known update was in 1994, indicating potential staleness and lack of recent maintenance.
• Specific parameters, measurement methods, and sample depth are unknown without accessing full metadata.
