Tree Ring Chronology from Lower Canyon Stein Valley

Tree ring width measurements from Douglas fir (PSME) trees in British Columbia, Canada, used for paleoclimate reconstruction. The chronology covers a 398-year period from 352 to -45 calendar years before present. This dataset is archived by NOAA's World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual tree ring width series.
• Calibrate the chronology against known climate events using the provided calendar year BP time index.
• Study the growth response of Douglas fir (PSME) to environmental stressors over a multi-century period.

Strengths

• Chronology spans 398 years, providing a multi-century climate proxy.
• Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, with a last update recorded in 1995.
• Specific sample size, geographic precision, and measurement parameters are not detailed in the provided metadata.
