Verchoyansk Tree Ring Chronology From 281 BC

322 calendar years of tree-ring width data from the Verchoyansk and Cakker river sites in Russia, Eastern Europe. The dataset is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. This paleoclimatology study was last updated in January 1991.

Use Cases

• Reconstruct historical temperature or precipitation anomalies using the tree-ring width chronology as a climate proxy.
• Calibrate the tree-ring chronology against other paleoclimate records from the Verchoyansk region.
• Analyze growth patterns in the tree-ring series to identify extreme climate events like droughts or cold periods.
• Compare the chronology from the Cakker river site with other Siberian tree-ring datasets to assess regional climate coherence.

Strengths

• Time series coverage spans 322 calendar years, from 281 to -41 years before present.
• Data originates from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1991, indicating potential staleness relative to modern collection standards.
• Specific sample size, geographic coordinates, and measurement parameters are not provided in the input.
• Data is limited to two specific river sites in Russia, which may not be representative of broader regional patterns.
