Arizona Tree Ring Chronology from 450 to -30 Years Before Present

Tree ring data from the San Francisco Peaks in Arizona provides a 480-year chronology for paleoclimate reconstruction. The dataset, archived by NOAA's World Data Service for Paleoclimatology, was contributed by researcher Graybill and last updated in 1980.

Use Cases

• Reconstruct past temperature or precipitation anomalies using annual tree-ring width measurements.
• Calibrate climate models by comparing the tree-ring chronology against known historical climate events.
• Analyze growth patterns to infer ecological stress periods within the 480-year time span.
• Cross-date archaeological wood samples from the region using this established master chronology.

Strengths

• Covers a 480-year time period from 450 to -30 calendar years BP.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last update recorded in 1980.
• Specific row count, measurement parameters, and file formats are unknown.
