A paleoclimatology dataset from the NOAA National Centers for Environmental Information provides tree ring parameters from Katherine Creek in Canada's Northwest Territories. The time series covers 483 years, from 444 to -39 calendar years before present. This archived study was published by NOAA NCEI in 1989.
Use Cases
- Reconstruct past temperature or precipitation anomalies using annual tree ring width measurements.
- Calibrate climate models by comparing the tree ring chronology with other proxy records for the same time period.
- Analyze growth trends and extreme events captured in the ring data to infer ecological responses to past climate shifts.
Strengths
- Covers a 483-year time period for long-term trend analysis.
- Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, last updated in 1989.
- Sample size and specific parameters like ring width are unknown from the description.
- Geographic scope is limited to a single site in the Northwest Territories.
