Spider Rock Tree Ring Chronology for Arizona Paleoclimate

NOAA/WDS Paleoclimatology archives a tree-ring chronology from the Spider Rock site in Arizona. The dataset covers a 370-year period from 349 to -21 calendar years before present. NOAA National Centers for Environmental Information (NCEI) curates this data for paleoclimate research.

Use Cases

• Reconstruct past drought indices using tree-ring width measurements.
• Calibrate climate models by comparing ring-width chronology with known historical climate events.
• Analyze growth anomalies in the chronology to identify volcanic or extreme weather events.
• Establish a dated master chronology for cross-referencing other archaeological samples from the region.

Strengths

• Covers a 370-year period from 349 to -21 BP.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends 21 years before present, limiting analysis of the most recent climate.
• Geographic scope is limited to a single site (Spider Rock) in Arizona.
