204 calendar years of tree ring data from the Yukon Territory, Canada, extending from 204 to -48 years before present. The dataset is part of the NOAA/WDS Paleoclimatology archive, contributed by the NOAA National Centers for Environmental Information. It was archived for public access in 1998.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
- Calibrate climate models by comparing the time-series data against known historical climate events.
- Analyze growth patterns in the Donjek region to study ecological responses to long-term climate change.
Strengths
- Covers a 252-year time period (204 to -48 BP) for climate analysis.
- Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage is limited to a specific 252-year window, not continuous to present.
- Data is geographically focused on a single location in the Yukon Territory, Canada.
- The dataset was last updated in 1998, indicating potential staleness in metadata or availability.
