Alaskan Tree Ring Paleoclimate Series from Gulkana Glenallen

NOAA/WDS Paleoclimatology provides a tree-ring dataset from the Gulkana Glenallen site in Alaska. The time series covers 132 years, from 96 to -36 calendar years before present. This archived study was published by the NOAA National Centers for Environmental Information 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 proxy record with instrumental data for the Alaskan region.
• Analyze climate periodicity and extreme events over a 132-year span from the calendar years before present data.

Strengths

• Data originates from the authoritative NOAA National Centers for Environmental Information (NCEI).
• Covers a specific 132-year time period in calendar years before present (BP).

Limitations

• Dataset is temporally stale, with a last update date of 1986.
• Specific row count, column names, and measurement parameters are unknown from the provided metadata.
