Grandfather Mountain Tree Ring Chronology from 390 to 33 BCE

Tree ring width measurements from Grandfather Mountain, North Carolina, USA. The chronology covers 423 years, from 390 to 33 BCE (calendar years before present). This archived paleoclimatology study was produced by the NOAA National Centers for Environmental Information and last updated in 1983.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing annual tree ring width variations.
• Calibrate and validate climate models using a precisely dated, multi-century proxy record from North Carolina.
• Study the frequency and impact of historical drought events through identified narrow ring sequences.
• Establish cross-dating references for other tree ring collections from the Appalachian region using the shared chronology.

Strengths

• Chronology spans 423 years, providing a multi-century climate proxy.
• Precise temporal coverage defined from 390 to 33 BCE.
• Data is archived and maintained by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last update recorded in 1983.
• Geographic coverage is limited to a single site (Grandfather Mountain, NC).
• Sample size and replication depth of the underlying tree cores are unknown.
