NOAA's Paleoclimatology archive provides a tree ring chronology from the Hazel Creek site in Canada's Yukon Territory. The data covers 320 years, from 271 to -49 calendar years before present. This study was archived by the NOAA National Centers for Environmental Information in 1999.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
- Calibrate radiocarbon dates or validate other paleoclimate proxies by aligning the tree ring time series.
- Analyze climate sensitivity and growth response by correlating ring measurements with known historical climate events.
Strengths
- Data spans 320 calendar years, providing a multi-century climate record.
- Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends at -49 BP (approximately 1999 CE), lacking recent decades.
- Geographic scope is limited to a single site (Hazel Creek) in the Yukon.
