143 to -36 calendar years before present (BP) of tree ring parameters from an East Yakutat site in Alaska. The data is archived by the NOAA National Centers for Environmental Information under its Paleoclimatology World Data Service. This study was published in 1986.
Use Cases
- Reconstruct past temperature or precipitation anomalies using tree ring width or density parameters.
- Calibrate climate models by comparing the tree ring chronology with known historical climate events.
- Analyze growth trends and extreme events recorded in the tree ring parameters for the East Yakutat region.
Strengths
- Chronology spans 179 years, from 143 to -36 BP.
- Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- The dataset's last update was in 1986, making it temporally stale for contemporary analysis.
- Specific sample size, measured parameters, and geographic precision are not detailed in the provided metadata.
