Mongolian Tree Ring Chronology From 337 to 48 BC

A Mongolian tree ring chronology from the Khar Uzuur site provides paleoclimate data for Eastern Asia. The time series covers 385 years, from 337 to 48 calendar years before present. It was archived by the NOAA National Centers for Environmental Information in 1998.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width index time series.
• Calibrate climate models by comparing the chronology data with simulated historical climate variables.
• Analyze the frequency of extreme climatic events, such as droughts, from the ring width measurements.
• Study ecological responses to climate change by examining growth patterns in the tree ring records.

Strengths

• Time series spans 385 calendar years, providing a multi-century record.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Dataset has not been updated since its archival in 1998, potentially lacking modern recalibration.
• Geographic scope is limited to a single site (Khar Uzuur) in Mongolia.
