Tree Ring Chronology from Graves Lookout in British Columbia

A 279-year tree ring chronology from Graves Lookout, British Columbia, Canada, covering 230 to -49 calendar years before present. The dataset provides parameters for dendrochronological analysis and climate reconstruction. It was archived by NOAA's World Data Service for Paleoclimatology and last updated in 1999.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing annual tree ring width variations.
• Calibrate climate models using the 279-year proxy record to validate simulations for the region.
• Study ecological responses to historical climate events by examining growth patterns in the chronology.
• Perform cross-dating with other regional tree ring series to build a longer, more robust climate record.

Strengths

• 279-year continuous chronology providing a multi-century climate proxy.
• Geographically specific data point from British Columbia, Canada for localized analysis.

Limitations

• Data is temporally stale, last updated in 1999, potentially missing modern methodological revisions.
• Limited geographic scope to a single site (Graves Lookout), reducing regional representativeness.
