Tree ring width measurements from Lac Romanel, Quebec, Canada, provide a climate proxy record. The chronology spans 167 years, from 129 to -38 calendar years before present. NOAA's National Centers for Environmental Information archived this paleoclimatology study in 1988.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree ring width parameter as a proxy.
- Calibrate radiocarbon dating models by aligning the tree ring chronology with known calendar years before present.
- Analyze climate sensitivity by correlating the ring width time series with other regional paleoclimate records.
Strengths
- Chronology covers a specific 167-year period from 129 to -38 BP.
- Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.
Limitations
- The dataset is temporally stale, with a last update date of 1988.
- Sample size and replication depth are unknown, limiting statistical confidence.
- Geographic coverage is limited to a single site in Quebec, Canada.
