Alaskan Tree Ring Chronology for Paleoclimate Reconstruction

528 years of tree ring data from the Wrangell Mountains in Alaska, covering the period from 479 to -49 calendar years before present. This paleoclimatology dataset was archived by NOAA's National Centers for Environmental Information and is associated with the ITRDB AK116 site. The study was last updated in 1999.

Use Cases

• Calibrate tree ring width measurements to reconstruct past temperature anomalies for the Wrangell Mountains region.
• Analyze the chronology data to identify periods of climatic stress or growth suppression in the tree record.
• Compare this Alaskan tree ring series with other chronologies to study hemispheric climate teleconnections.
• Use the dated annual resolution to validate or extend climate model simulations for the last millennium.

Strengths

• 528-year temporal coverage provides a multi-century climate record.
• Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1999, indicating it may not reflect the most current research or methods.
• Specific parameters, sample depth, and measurement statistics are not detailed in the provided description.
