Tree ring data from British Columbia, Canada, spans 505 calendar years from 490 to -15 years before present. This archived paleoclimatology study is maintained by NOAA's National Centers for Environmental Information under its World Data Service. The data was archived in 1965.
Use Cases
- Reconstruct past temperature or precipitation anomalies using annual tree ring width measurements.
- Cross-date and validate other tree ring chronologies from the Pacific Northwest region using this series.
- Analyze long-term environmental stress events recorded in the ring density or isotopic parameters.
- Calibrate radiocarbon dating curves using the precisely dated tree ring sequence.
Strengths
- 505-year temporal coverage provides a multi-century environmental record.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends 15 years before present (1965), lacking recent decades.
- Sample size and replication statistics for the tree ring series are unknown.
- Geographic coverage is limited to a single site at Pavilion Lake, British Columbia.
