Alaskan Tree Ring Chronology From 278 to -36 BP

A 314-year tree-ring chronology from the Cordova Airport area in Alaska, covering the period from 278 to -36 calendar years before present. The dataset is part of the NOAA/WDS Paleoclimatology archive and was produced by the NOAA National Centers for Environmental Information. The data was last updated in the archive in 1986.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a proxy.
• Calibrate the tree-ring chronology against known climate events within the 314-year period for climate model validation.
• Analyze the growth response and sensitivity of trees in coastal Alaska to environmental stressors over several centuries.

Strengths

• Covers a 314-year time period from 278 to -36 BP.
• Sourced from the authoritative NOAA/WDS Paleoclimatology archive.

Limitations

• The dataset's last known update was in 1986, indicating potential staleness.
• Specific sample size, geographic precision, and measurement parameters are not detailed in the provided description.
