Indigirka Tree Ring Chronology for Paleoclimate Reconstruction

Tree ring width data from the Indigirka region of Sakha, Russia, used for paleoclimate studies. The chronology covers a 440-year period from 396 to -44 calendar years before present (BP). This dataset is part of the NOAA NCEI World Data Service for Paleoclimatology archives.

Use Cases

• Reconstruct past temperature or precipitation anomalies using tree ring width as a climate proxy.
• Calibrate the chronology against known historical climate events using the provided calendar year BP time scale.
• Analyze growth patterns in the Sakha region to infer ecological responses to past climate shifts.
• Compare this Siberian Arctic tree ring series with other global proxy records for hemispheric climate analysis.

Strengths

• 440-year chronology providing multi-century climate context.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, with a last recorded update in 1994.
• The geographic coverage is limited to a single region (Sakha, Russia).
• Specific sample depth, measurement parameters, and metadata details require external review.
