Tree ring width measurements from Douglas-fir (Pseudotsuga menziesii) trees in Washington state, United States. The chronology covers a 699-year period from 662 to 37 years before present. Data is archived by the NOAA National Centers for Environmental Information's World Data Service for Paleoclimatology.
Use Cases
- Reconstruct past temperature or precipitation anomalies using annual tree ring width as a proxy.
- Calibrate radiocarbon dating or other chronological models with the dated tree ring series.
- Analyze growth response and climate sensitivity of Pseudotsuga menziesii (PSME) over a 699-year period.
- Compare this local tree ring chronology with regional climate records to validate reconstruction models.
