Tree ring width measurements from Tombstone Mountain in Yukon Territory, Canada, provide a climate proxy record. The chronology spans 462 years, covering the period from 420 to -42 calendar years before present. This archived study was published by NOAA National Centers for Environmental Information in 1992.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing the annual tree ring width series.
- Calibrate climate models for the Yukon region using the 462-year proxy record.
- Study ecological resilience by examining growth patterns in trees older than 100 years.
- Cross-date and validate other paleoclimate archives from northwestern North America using this chronology.
Strengths
- Chronology spans 462 calendar years, providing a multi-century climate record.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, with no updates since its publication in 1992.
