Oregon Tree Ring Chronology From 853 to 32 BCE

A tree ring chronology from the Frederick Butte site in Oregon, United States. The dataset provides paleoclimatic parameters covering the period from 853 to 32 calendar years before present. It is archived by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing annual ring-width measurements.
• Calibrate climate proxy models using the dated tree ring series from this specific Oregon location.
• Perform cross-dating analysis to validate or extend regional dendrochronological records.
• Study long-term ecological responses to climate events using the millennial-scale tree growth data.

Strengths

• Time series covers approximately 821 years (853 to 32 BP)
• Data is curated and archived by the authoritative NOAA NCEI World Data Service

Limitations

• Dataset was last updated in 1982, indicating potential staleness relative to modern methods
• Specific sample depth, measurement parameters, and site details are not provided in the summary
