Alaskan Tree Ring Chronology from Eagle Summit Below Treeline

263 years of tree ring data from a site below the treeline at Eagle Summit, Alaska, covering the period 216 to -47 calendar years before present. This paleoclimatology study was archived by NOAA's National Centers for Environmental Information. The dataset was last updated in 1997.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
• Calibrate the chronology against other proxy records for the 263-year period from 216 to -47 BP.
• Analyze growth response to climate stressors at the Eagle Summit below-treeline site.
• Compare this Alaskan tree ring series with other ITRDB chronologies for regional climate patterns.

Strengths

• Covers a 263-year time period from 216 to -47 BP.
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection.

Limitations

• Data is temporally stale, last updated in 1997.
• Specific sample depth, measurement parameters, and site details are not provided in the summary.
