Gros Ventre Tree Ring Chronology From 550 to 21 BC

571-year tree-ring chronology from the Gros Ventre Uhl Hill site in Wyoming, United States. The data covers the period from 550 to 21 calendar years before present, providing a proxy record for past climate conditions. It is archived by the NOAA National Centers for Environmental Information's World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past temperature or precipitation anomalies for Wyoming using the annual tree-ring width series.
• Calibrate regional climate models by comparing the tree-ring chronology with instrumental records from overlapping periods.
• Analyze the frequency of extreme growth years (narrow or wide rings) as proxies for droughts or favorable growing seasons.
• Cross-date this chronology with other regional tree-ring datasets to validate and extend climate reconstructions.

Strengths

• Chronology spans 571 consecutive years from 550 to 21 BC.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends 21 years before present, lacking overlap with the modern instrumental era.
• Geographic scope is limited to a single site (Gros Ventre Uhl Hill) in Wyoming.
