Frederick Butte Tree Ring Widths from 750 to 37 BCE

Tree-ring width measurements from a site in Oregon, USA, covering a 787-year period from 750 to 37 BCE. The dataset is archived by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. It was last updated in the NCEI system in 1987.

Use Cases

• Reconstruct annual temperature or precipitation anomalies for the Pacific Northwest using the tree-ring width time-series.
• Calibrate the tree-ring width chronology against other regional paleoclimate proxies for the period 750-37 BCE.
• Analyze the frequency and severity of drought events in pre-modern Oregon from variations in annual ring width.
• Use the dated tree-ring series to anchor and cross-date other undated wood samples from the region.

Strengths

• Covers a specific 787-year period (750 to 37 BCE) for long-term trend analysis.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Data collection and last update was in 1987, potentially missing modern reanalysis or calibration.
• Geographic coverage is limited to a single site (Frederick Butte, Oregon), reducing regional representativeness.
• The raw sample data and specific measurement counts are unavailable for assessing sample depth.
