Kokanee Tree Ring Chronology from British Columbia

Tree ring measurements from Kokanee, British Columbia, span 287 years from 240 to -47 calendar years before present. The NOAA National Centers for Environmental Information archives this paleoclimatology study for climate reconstruction. Data was last updated in the repository in 1997.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
• Calibrate radiocarbon dating models by correlating the ring series with known calendar years.
• Analyze climate extremes and resilience by examining patterns in the annual growth index data.
• Compare this chronology with other regional tree ring datasets to study spatial climate patterns.

Strengths

• Covers a 287-year time period from 240 to -47 BP.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, last updated in the repository in 1997.
• Geographic coverage is limited to a single site in British Columbia, Canada.
• The exact sample size, measurement parameters, and data structure are unspecified.
