Tree ring data from Prince William Sound, Alaska, provides a paleoclimate record. The chronology covers a 787-year period from 750 to 37 calendar years before present. Data is archived by the NOAA National Centers for Environmental Information.
Use Cases
- Reconstruct past temperature or precipitation anomalies using tree ring width measurements.
- Calibrate climate models by comparing the tree ring chronology with known historical climate events.
- Analyze growth trends and environmental stressors for the Tsuga mertensiana (TSME) species over centuries.
- Establish a dated timeline for regional paleoclimate studies by cross-referencing this chronology with other proxy records.
Strengths
