Polar Urals Upper Timberline Tree-Ring Chronology from 409 BC

Tree-ring width measurements from the Polar Urals upper timberline provide a 427-year climate proxy record. The dataset, archived by NOAA NCEI's World Data Service for Paleoclimatology, covers the period from 409 to 18 years before present. It was contributed by researcher Shiyatov and last updated in the NOAA system in 1968.

Use Cases

• Reconstruct past summer temperatures by analyzing the annual tree-ring width series.
• Calibrate climate models using the precisely dated chronology from 409 BC to 18 BC.
• Study ecological shifts at the upper timberline by examining growth patterns in the ring-width data.
• Compare this high-latitude tree-ring series with other paleoclimate proxies for hemispheric climate analysis.

Strengths

• Covers a 427-year continuous period from 409 to 18 years before present.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends over 2000 years ago, limiting analysis of recent climate.
• Geographic scope is restricted to a single site in the Polar Urals, Russia.
• Data was last updated in the NOAA archive in 1968, indicating potential staleness of metadata.
