Tree Ring Chronology for Climate Reconstruction in Yukon Territory

Tree ring width measurements provide a proxy climate record from the Yukon Territory, Canada. The dataset covers a period from 291 to -48 calendar years before present (BP), indicating it includes both past and future-dated calibration points. It is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1998.

Use Cases

• Reconstructing past temperature or precipitation anomalies using tree ring width as a proxy.
• Calibrating radiocarbon dates or other chronological models against the provided tree ring chronology.
• Analyzing long-term climate trends in the Yukon Territory across the recorded time span.
• Comparing this local tree ring record with other regional paleoclimate proxies for spatial pattern analysis.

Strengths

• Data spans 339 years of chronological coverage (from 291 to -48 BP).
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1998, potentially lacking modern re-calibration or metadata standards.
• The geographic coverage is limited to a single site in the Yukon Territory, limiting broad spatial analysis.
• Specific sample depth, replication statistics, and measurement parameters are not detailed in the provided description.
