Kenai Peninsula Tree Ring Chronology for Climate Reconstruction

268 years of tree ring data from the Kenai Lowlands in Alaska, covering 230 to -38 calendar years before present. The dataset is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1988. It provides parameters for dendroclimatological studies.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the annual tree ring width chronology.
• Calibrate climate models by comparing the tree ring proxy record with instrumental data for the Alaskan region.
• Analyze ecological resilience and growth patterns in response to past climatic events recorded in the ring sequences.

Strengths

• 268-year temporal coverage provides a multi-century climate proxy record.
• Data is curated and archived by the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last update recorded in 1988.
• The specific parameters, sample size, and measurement methods are not detailed in the provided description.
