Mongolian Tree Ring Chronology from 309 to 48 BC

Tree ring width measurements from the Horin Bugatyin Davaa site in Mongolia provide a paleoclimate record. The chronology spans 357 years, from 309 to 48 BC, created by researcher Jacoby and archived by NOAA NCEI. This dataset was last updated in the repository in 1998.

Use Cases

• Reconstruct past temperature or precipitation anomalies in Eastern Asia using annual tree ring width as a proxy.
• Calibrate climate models by comparing the tree ring chronology against known historical climate events within its 357-year span.
• Analyze growth patterns and environmental stress responses in trees from Mongolia's specific geographic location.
• Establish a regional master chronology for cross-dating other tree ring samples from Mongolia and surrounding areas.

Strengths

• 357-year continuous chronology from 309 to 48 BC provides a substantial pre-modern climate record.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Dataset is temporally stale, with a last repository update in 1998.
• Geographic coverage is limited to a single site in Mongolia, limiting regional generalization.
• Specific measurement parameters, sample depth, and potential missing years are not detailed in the provided description.
