Tree ring width measurements from a site in Quebec, Canada, provide a paleoclimate record. The chronology spans 244 years, from 199 to -45 calendar years before present. The data was archived by NOAA's National Centers for Environmental Information in 1995.
Use Cases
- Calibrate tree ring width measurements against known climate indices for the Quebec region to develop climate proxies.
- Analyze the time-series of ring widths to identify periods of growth suppression or release, indicating past environmental stress events.
- Compare this chronology with other ITRDB series from North America to assess spatial patterns of past climatic events.
- Use the dated sequence to validate or extend radiocarbon calibration curves for the specific time period covered.
Strengths
- Time series covers a specific 244-year period from 199 to -45 BP.
- Data is part of the International Tree-Ring Data Bank (ITRDB), a standardized global archive.
- Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Dataset is small, containing only a single site chronology (ITRDB code CANA141).
- Data is temporally stale, last updated in 1995 and may lack modern reanalysis.
- Geographic coverage is limited to one location in Quebec, limiting broad regional inferences.
