Campbell Dolomite Upland Tree Ring Chronology from Yukon Territory

Tree ring width measurements from the Campbell Dolomite Upland site in Yukon Territory, Canada, provide a climate proxy record. The chronology spans 654 years, covering the period from 775 to 122 calendar years before present. This archived study is maintained by NOAA's National Centers for Environmental Information and World Data Service for Paleoclimatology.

Use Cases

• Reconstruct annual temperature or precipitation anomalies by calibrating tree ring width measurements against modern instrumental records.
• Analyze the timing and magnitude of volcanic cooling events within the 654-year chronology.
• Identify periods of climatic stress or growth suppression in the tree ring series for ecological studies.
• Compare this Yukon tree ring chronology with other regional series to assess spatial climate patterns.

Strengths

• Covers a 654-year continuous time series from 775 to 122 BP.
• Part of the authoritative NOAA/NCEI Paleoclimatology archive with standardized metadata.

Limitations

• Single-site chronology from one tree species, limiting spatial representativeness.
• Calendar year BP dating requires conversion for direct comparison with Common Era datasets.
• Unknown sample depth (number of trees/cores) affects signal strength confidence.
