A 371-year tree-ring chronology from Discovery Ridge in Canada's Northwest Territories, covering the period from 330 to -41 calendar years before present. The dataset was archived by NOAA's National Centers for Environmental Information under its World Data Service for Paleoclimatology. This study was last updated in 1991.
Use Cases
- Reconstruct historical temperature or precipitation anomalies by analyzing the tree-ring width series.
- Calibrate climate models using the dated proxy record of environmental conditions from 330 to -41 BP.
- Study ecological resilience and growth patterns of long-lived trees (greater than 200 years) in the Northwest Territories.
- Perform cross-dating analysis with other regional chronologies using the annual resolution time series.
Strengths
- Time series spans 371 calendar years (330 to -41 BP).
- Data originates from trees older than 200 years, providing a long-term biological record.
- Archived and maintained by the authoritative NOAA NCEI World Data Service.
Limitations
- Dataset is temporally stale, with a last update recorded in 1991.
- Geographic scope is limited to a single site (Discovery Ridge) in the Northwest Territories.
- Specific parameters, sample size, and measurement details are not provided in the available metadata.
