293 calendar years of tree ring data from Wakuach Lake in Quebec, Canada, covering the period from 255 to -38 years before present. The dataset is archived by the NOAA National Centers for Environmental Information under its Paleoclimatology World Data Service. The associated study was published in 1988.
Use Cases
- Calibrating climate models by correlating annual ring-width measurements with temperature and precipitation proxies.
- Reconstructing past climate conditions for the Quebec region using the dated tree-ring chronology.
- Analyzing growth anomalies in the chronology to identify volcanic or climatic disturbance events.
Strengths
- Covers a 293-year time period for long-term trend analysis.
- Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- The dataset is temporally stale, with a last update recorded in 1988.
- Geographic scope is limited to a single lake site in Quebec.
