Tree Ring Chronology from Grey Creek, British Columbia (208-Year Record)

208 years of tree ring data from 161 to -47 calendar years before present, providing a proxy climate record. The dataset was produced by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. It was archived and last updated in 1997.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology as a proxy.
• Calibrate climate models by comparing the 208-year tree ring time series with other paleoclimate records.
• Analyze growth patterns and climate sensitivity of trees in the British Columbia region from the provided parameters.
• Establish a dated chronology for the Grey Creek site to support cross-dating with other tree ring collections.

Strengths

• Covers a 208-year time period (161 to -47 BP) for climate analysis.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Includes geospatial location data for British Columbia, Canada.

Limitations

• Data is temporally stale, last updated in 1997, and may not reflect current research standards.
• The specific sample size (number of tree cores or series) is unknown, limiting assessment of statistical robustness.
• Potential geographic bias as data is from a single location (Grey Creek).
