Polar Ural Tree Ring Chronology for Climate Reconstruction

Tree ring width measurements from the Polar Ural region of Russia, used for paleoclimate studies. The chronology covers a period from 287 to -40 calendar years before present. This dataset is archived by the NOAA National Centers for Environmental Information's World Data Service for Paleoclimatology and was last updated in 1990.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width time series.
• Calibrate climate proxy models using the dated tree ring chronology spanning over three centuries.
• Study extreme climate events in the Polar Urals by identifying narrow or wide ring anomalies in the series.
• Compare this high-latitude tree ring record with other proxy datasets to analyze hemispheric climate patterns.

Strengths

• Chronology provides a continuous proxy record covering 327 years (from 287 to -40 BP).
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last known update was in 1990, indicating potential staleness and lack of recent maintenance.
• Specific sample size, measurement methods, and site replication details are not provided in the available metadata.
