Canyon de Chelly Ponderosa Pine Tree Ring Chronology

Tree ring width measurements from Ponderosa Pine (PSME) trees at Canyon de Chelly, Arizona. The chronology covers 596 years, from 574 to -22 calendar years before present. This paleoclimatology study was archived by NOAA NCEI's World Data Service.

Use Cases

• Reconstruct annual precipitation or drought indices for the southwestern US using tree ring width as a proxy.
• Calibrate climate models by comparing the tree ring chronology against known historical climate events.
• Analyze long-term growth trends and climate sensitivity of Ponderosa Pine ecosystems in Arizona.
• Establish a dated tree ring chronology for cross-referencing with other regional paleoclimate records.

Strengths

• Chronology spans 596 calendar years, providing a multi-century climate record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last recorded update in 1972.
• Sample size and replication depth for the tree ring series are unknown.
