Tree ring width measurements from a site near Pine Pass in British Columbia, Canada, used for climate reconstruction. The chronology spans 286 years, from 253 to -33 calendar years before present. This archived study was contributed by Schweingruber to the NOAA NCEI World Data Service for Paleoclimatology and was last updated in 1983.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree ring width series as a climate proxy.
- Calibrate the chronology against other regional tree ring datasets to extend climate records.
- Analyze growth trends and extreme events captured in the ring width data for ecological studies.
- Validate radiocarbon dating or other chronological models using the established tree ring timeline.
Strengths
- Chronology covers a continuous 286-year period from 253 to -33 BP.
- Data is archived and curated by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, with a last update recorded in 1983.
- Geographic coverage is limited to a single site in British Columbia.
- The exact number of core samples, measurement methods, and potential measurement noise are not detailed in the provided description.
