207 calendar years of tree ring data from Douglas Fir (Pseudotsuga menziesii) trees at Big Boulder Creek, Washington, USA. The chronology spans from 207 to -25 years before present, archived by NOAA's National Centers for Environmental Information. The data was published in 1975.
Use Cases
- Analyze annual tree ring width variations to reconstruct past climate conditions like temperature or precipitation.
- Calibrate the chronology against other regional records using the calendar year BP time series.
- Study the growth response of Pseudotsuga menziesii (PSME) to environmental changes over a 232-year period.
Strengths
- 232-year time series from 207 to -25 calendar years BP.
- Data is part of the NOAA/NCEI World Data Service for Paleoclimatology, an authoritative archive.
Limitations
- Data is from a single site (Big Boulder Creek), limiting regional representativeness.
- The dataset is temporally stale, with a last updated date of 1975.
- Specific sample size (number of trees or cores) and measurement parameters are unknown.
