412-year tree ring chronology from 370 to -42 calendar years before present, providing proxy climate data. The dataset was archived by NOAA's World Data Service for Paleoclimatology and is associated with NCEI study type Tree Ring. The data was last updated in the archive in 1992.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree ring width chronology as a proxy.
- Calibrate climate models by comparing the 412-year tree ring record with instrumental data from the modern period.
- Analyze growth trends in trees older than 100 years to study ecological responses to historical climate events.
- Perform cross-dating of tree ring sequences from the Yukon Territory to validate regional chronologies.
Strengths
- Covers a 412-year time period (370 to -42 BP), providing a multi-century climate proxy.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, with the last recorded update to the archive occurring in 1992.
- Geographic coverage is limited to a single site in the Richardson Mountains, Yukon Territory, Canada.
- The exact sample size (number of tree cores or series) and measurement parameters are unknown from the provided metadata.
