Arizona Ponderosa Pine Tree Ring Chronology from 320 to 36 BCE

Tree-ring width measurements from a single-site chronology of Ponderosa pine trees in Arizona, covering 356 years from 320 to 36 BCE. The dataset was archived by NOAA's World Data Service for Paleoclimatology and contributed by researcher Graybill. It was last updated in the NOAA system in 1986.

Use Cases

• Reconstruct past climate conditions like precipitation by analyzing annual tree-ring width variations.
• Calibrate radiocarbon dating timelines using the precisely dated tree-ring chronology.
• Study the growth response of Ponderosa pine (species code PIPO) to environmental stressors over three centuries.

Strengths

• Data covers a continuous 356-year period from 320 to 36 BCE.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Single-site data from 'Sit. Gravel Pit' limits geographic representativeness for broader regional analysis.
• The dataset's last recorded update was in 1986, potentially lacking modern quality reassessments.
