Mongolian Tree Ring Chronology from Urgun Nars Spanning 345 Years

299 to -46 calendar years before present (BP) of tree ring data from the Urgun Nars site in Mongolia. The dataset contains parameters for paleoclimate reconstruction and is archived by the NOAA National Centers for Environmental Information (NCEI) World Data Service for Paleoclimatology. The associated study was last updated in 1996.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing tree ring width parameters.
• Calibrate climate models for Eastern Asia using the 345-year chronology from this site.
• Study long-term environmental stress events in Mongolian forests through variations in ring density data.
• Correlate this local tree ring record with other regional paleoclimate proxies to identify broader climate patterns.

Strengths

• Time series covers 345 calendar years (299 to -46 BP).
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Provides a focused geographic record for a specific site in Mongolia.

Limitations

• Temporal coverage ends 46 years before present, limiting analysis of the most recent climate period.
• Data is from a single site (Urgun Nars), which may not represent broader regional conditions.
• The dataset was last updated in 1996, indicating potential staleness in metadata or documentation.
