Alaskan Tree Ring Chronology from Willow Island (181 to -33 BP)

NOAA/WDS Paleoclimatology archives a tree-ring chronology from Willow Island, Alaska. The data covers the period from 181 to -33 calendar years before present. This study was contributed by Schweingruber and archived by NOAA National Centers for Environmental Information, with a last update recorded in 1983.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology.
• Calibrate climate models by comparing the tree-ring proxy data with instrumental records for the Alaskan region.
• Analyze growth patterns and environmental stressors from the measured tree-ring parameters.
• Study long-term ecological changes in Arctic willow populations over the recorded time span.

Strengths

• Time series covers a 214-year period (181 to -33 BP).
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.

Limitations

• Dataset is temporally stale, with a last update date of 1983.
• Specific sample size (row count) and measured parameters (columns) are not provided in the description.
