Tree ring width measurements from a site in Newfoundland, Canada, form this paleoclimate dataset. The chronology covers 296 years, from 250 to -46 calendar years before present. NOAA National Centers for Environmental Information archives and provides the data, which was last updated in 1996.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width time-series.
- Calibrate the chronology against other regional proxies using its documented calendar year BP timeline.
- Study the response of boreal tree species to climatic events within the 296-year covered period.
Strengths
- Time-series covers a specific 296-year period from 250 to -46 BP.
- Data is archived and curated by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- The dataset's last update was in 1996, indicating potential staleness relative to modern methods.
- The single geographic location (Newfoundland) limits broader spatial climate analysis.
- Specific sample depth, measurement parameters, and potential error ranges are not detailed in the provided description.
