Alaskan Tree Ring Chronology from Tustemena Moraine (160 BP)

NOAA/WDS Paleoclimatology archives a tree ring chronology from the Tustemena Moraine in Alaska. The dataset provides parameters for climate reconstruction, covering the period from 160 to -38 calendar years before present. It is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using tree ring width parameters from the Tustemena Moraine site.
• Calibrate climate models by comparing the tree ring chronology time series against instrumental records for Alaska.
• Analyze the frequency of extreme climatic events in the 160 BP to -38 BP period through anomalies in the ring data.

Strengths

• Data spans a 198-year period from 160 to -38 calendar years BP, providing a multi-century climate record.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology, ensuring provenance.

Limitations

• Temporal coverage ends at -38 BP, indicating the dataset is not updated with recent centuries.
• Sample size, geographic representativeness, and specific parameter details are unknown from the description.
• The dataset was last updated in 1988, suggesting potential staleness in metadata or curation methods.
