A 464-year tree-ring chronology from Yoho Pass in British Columbia, Canada, provides paleoclimate data. The dataset, archived by NOAA NCEI's World Data Service for Paleoclimatology, covers the period from 424 to -40 calendar years before present. It was last updated in the NOAA system in 1990.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing the tree-ring width chronology as a climate proxy.
- Calibrate radiocarbon dating or other chronological models using the dated tree-ring series from 424 to -40 BP.
- Study ecological responses to historical climate events by examining growth patterns in the Yoho Pass tree-ring record.
- Compare this North American tree-ring chronology with other global paleoclimate proxy records to identify hemispheric climate patterns.
Strengths
- Covers a 464-year time period (424 to -40 BP) for long-term trend analysis.
- Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
- Provides a geographically specific record for British Columbia, Canada.
Limitations
- Data record ends at -40 BP (approximately 1990 AD), lacking recent decades.
- Sample size and replication depth for the tree-ring chronology are unknown from the description.
- Limited to a single geographic site (Yoho Pass), which may not represent broader regional climate.
