British Columbia Tree Ring Width Chronology from 750 to 37 BC

Tree ring width measurements from British Columbia, Canada, provide a 787-year chronology for reconstructing past climate. The data, archived by NOAA's World Data Service for Paleoclimatology, covers the period from 750 to 37 calendar years before present. This study is part of the PAGES North America 2K network for continental-scale climate analysis.

Use Cases

• Calibrate climate models by comparing tree-ring width chronologies against instrumental temperature and precipitation records.
• Analyze decadal to centennial-scale climate variability in the Pacific Northwest using the annual-resolution time-series.
• Reconstruct summer temperature or drought indices for British Columbia from the ring width proxy data.
• Contribute site-specific data to the PAGES North America 2K continental climate reconstruction network.

Strengths

• 787-year continuous chronology from 750 to 37 BC provides long-term context.
• Data is part of the authoritative PAGES 2K network for standardized continental reconstructions.
• Archived and maintained by NOAA's World Data Service for Paleoclimatology, ensuring long-term access.

Limitations

• Data was last updated in 1987, potentially missing modern methodological refinements.
• Single geographic location in British Columbia limits spatial representativeness.
• Unknown sample size (number of tree cores) and replication details affect uncertainty estimates.
