Tree ring width chronology data from the Franklin Mountains in Canada's Northwest Territories, spanning 358 years from 325 to -33 calendar years before present. The dataset was archived by NOAA's National Centers for Environmental Information World Data Service for Paleoclimatology and last updated in 1983.
Use Cases
- Reconstruct historical temperature or precipitation anomalies using the tree ring width time-series.
- Calibrate radiocarbon dating models by cross-referencing the dated tree ring chronology.
- Analyze growth response to environmental stressors by examining year-to-year variations in ring width.
Strengths
- 358-year continuous chronology from 325 to -33 BP.
- Data originates from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- Dataset is temporally stale, with a last update recorded in 1983.
- Geographic coverage is limited to a single site in the Franklin Mountains.
