Mt. Diablo Tree Ring Chronology from 305 to 47 BCE

Tree ring width measurements from Mt. Diablo State Park in California, spanning 352 years from 305 to 47 BCE. The dataset is part of the NOAA NCEI World Data Service for Paleoclimatology archive, contributed by researcher Stahle. It was last updated in the NOAA system in 1997.

Use Cases

• Reconstruct annual precipitation or drought indices for California using tree ring width as a proxy.
• Calibrate radiocarbon dating models by cross-referencing the tree ring chronology with known historical periods.
• Analyze climate periodicity and extreme events by examining the time-series of ring width measurements.
• Compare the Mt. Diablo chronology with other ITRDB series (e.g., ITRDB CA623) to assess regional climate signals.

Strengths

• Covers a specific 352-year period (305-47 BCE) for high-resolution temporal analysis.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Includes geographic location metadata for California, United States.

Limitations

• Temporal coverage ends 47 BCE, providing no data for the modern or recent historical period.
• Data was last updated in 1997, indicating potential staleness and lack of recent methodological revisions.
• Sample size, tree species, and replication depth are unknown, limiting assessment of statistical robustness.
