750 to -37 calendar years before present of tree-ring width measurements from the Campbell Dolomite Upland in Canada's Northwest Territories. The dataset is a paleoclimatology study archived by NOAA's National Centers for Environmental Information under the World Data Service. It was last updated in 1987.
Use Cases
- Reconstruct historical climate variables like temperature or precipitation using tree-ring width as a proxy.
- Analyze growth patterns and environmental stressors for trees in the Campbell Dolomite Upland region.
- Calibrate and validate climate models with empirical data spanning nearly 800 years before present.
- Study ecological responses to past climate events within the PAGES North America 2K network context.
Strengths
- Time series coverage spans approximately 787 years from 750 to -37 BP.
- Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, with a last update recorded in 1987.
- Specific sample size, geographic precision, and measurement methodologies are not detailed in the provided metadata.
