Tree Ring Chronology From Cassiar Highway In British Columbia

A tree ring chronology dataset from a site 28km south of Eddontenaion along the Cassiar Highway in British Columbia, Canada. The data cover the period from 239 to -36 calendar years before present (BP) and were archived by NOAA's World Data Service for Paleoclimatology. This record was last updated in 1986.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width chronology.
• Calibrate climate models using the precisely dated annual resolution of the tree ring series.
• Study ecological responses to historical climate events using the growth record captured in the rings.
• Compare this site's chronology with others from the ITRDB CANA5 network to analyze regional climate patterns.

Strengths

• Time series spans 275 years (from 239 to -36 BP), providing a multi-century record.
• Data is part of the authoritative International Tree-Ring Data Bank (ITRDB) collection curated by NOAA/NCEI.

Limitations

• The dataset's last update was in 1986, making it temporally stale for contemporary analysis without newer data.
• Specific parameters like ring width measurements or climate correlations are not detailed in the provided metadata.
