Tree ring width measurements from a site in the Northwest Territories, Canada, provide a paleoclimate record. The chronology spans 493 years, from 459 to -34 calendar years before present. This archived study was published by NOAA NCEI's World Data Service for Paleoclimatology in 1984.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width time-series.
- Calibrate the chronology against known climate events using the calendar years before present (BP) index.
- Compare this site's growth patterns with other ITRDB chronologies to study regional climate signals.
- Validate climate model outputs for the Holocene period using the 493-year proxy record.
Strengths
- Time-series spans 493 calendar years, providing a multi-century climate record.
- Data is archived and curated by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Dataset is temporally stale, with a last update date of 1984.
- Geographic coverage is limited to a single site (Hornby Cabin) in Northwest Territories, Canada.
- The raw sample size, measurement resolution, and replication statistics are unknown.
