Tree ring width chronology data from a site near Haines, Alaska, used for paleoclimate reconstruction. The chronology spans 158 years, from 122 to -36 calendar years before present. The dataset was archived by NOAA National Centers for Environmental Information and last updated in 1986.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width series.
- Calibrate climate proxy models using the dated tree ring chronology against known historical periods.
- Study ecological responses to climate events by examining growth patterns in the ring width data.
- Compare this Alaskan site chronology with other ITRDB records to analyze regional climate teleconnections.
Strengths
- Chronology spans a defined 158-year period from 122 to -36 BP.
- Data is part of the authoritative International Tree-Ring Data Bank (ITRDB) collection.
Limitations
- Dataset is temporally stale, with a last update date of 1986.
