Ord Mountain Ponderosa Pine Tree Ring Chronology from 380 to 37 BCE

380 to 37 BCE tree-ring width chronology from Ponderosa Pine trees at Ord Mountain, Arizona. The dataset is a paleoclimatology study archived by NOAA's World Data Service for Paleoclimatology. Data was last updated in the NOAA system in 1987.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a climate proxy.
• Calibrate radiocarbon dating or validate other paleoclimate records by cross-referencing the dated tree-ring series.
• Analyze growth response patterns to specific climatic events within the 380 to 37 BCE period captured in the ring measurements.

Strengths

• Covers a 343-year period from 380 to 37 BCE, providing a multi-century climate record.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last recorded update in 1987.
• Geographic scope is limited to a single site (Ord Mountain, Arizona).
• Sample size and replication statistics (e.g., number of tree cores) are unknown.
