Tree ring data from Douglas Fir (Pseudotsuga menziesii) trees at Hurricane Ridge, Washington spans 234 years, from 208 to -26 calendar years before present. The dataset is archived by NOAA National Centers for Environmental Information as part of its Paleoclimatology World Data Service. The original study was published in 1976.
Use Cases
- Reconstruct annual climate variables like temperature or precipitation from tree ring width measurements.
- Calibrate radiocarbon dating or other dating methods using the established 234-year chronology.
- Analyze growth patterns and environmental stressors recorded in the ring sequences of Douglas Fir.
- Compare this local chronology with other regional tree ring datasets to study spatial climate patterns.
