Mongolian Tree Ring Chronology from 380 to 45 BC

425 years of tree-ring width data from the Turgen-charchira mountain region in Mongolia, spanning from 380 to 45 BC. The dataset is part of the International Tree-Ring Data Bank (ITRDB) and was archived by NOAA's World Data Service for Paleoclimatology. This study was last updated in January 1995.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width time-series.
• Calibrate climate models by comparing the tree-ring proxy record with simulated historical climate data.
• Analyze the frequency of extreme climatic events, such as droughts, from the ring-width chronology.
• Study the response of high-altitude Mongolian forests to past climate changes recorded in the ring sequences.

Strengths

• Covers a 425-year time period from 380 to 45 BC.
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection.
• Provides a proxy climate record for a specific geographic location in Mongolia.

Limitations

• Data is temporally stale, last updated in 1995.
• Limited geographic scope to a single mountain site in Mongolia.
• Unknown sample size and replication depth for the tree-ring chronology.
