Hart's Pass Tree Ring Chronology for Paleoclimate Reconstruction

NOAA/WDS Paleoclimatology archives a tree-ring chronology from Hart's Pass, Washington, USA. The dataset provides parameters for dendroclimatic analysis covering a period from 479 to -41 calendar years before present. This study was published by NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a proxy.
• Calibrate the chronology against known climate events using the provided calendar year BP time scale.
• Analyze long-term climate trends in Washington State by examining the ~520-year tree-ring record.
• Compare this site's chronology (ITRDB WA067) with other regional tree-ring datasets to assess spatial climate patterns.

Strengths

• Data spans approximately 520 calendar years, providing a multi-century climate record.
• Archived by the authoritative NOAA National Centers for Environmental Information under the World Data Service.

Limitations

• Temporal coverage ends at 41 BC (calendar year -41 BP), with no modern data for recent climate comparison.
• The dataset's last documented update was in 1991, indicating potential staleness in metadata or availability.
• Specific parameters, sample depth, and measurement statistics are not detailed in the provided description.
