Robinson Mountain Tree Ring Chronology for Climate Reconstruction

Tree ring width measurements from ponderosa pine (PIPO) at Robinson Mountain in Arizona, used for paleoclimate studies. The chronology covers a 356-year period from 320 to -36 calendar years before present. Data was archived by NOAA NCEI's World Data Service for Paleoclimatology in 1986.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology as a proxy.
• Calibrate the tree ring series against known climate events within the 320 to -36 BP time range.
• Analyze growth patterns in ponderosa pine (PIPO) for ecological studies in Arizona.
• Compare this ITRDB site AZ539 chronology with other regional tree ring datasets for spatial climate analysis.

Strengths

• 356-year continuous chronology providing a multi-century climate record.
• Data is part of the authoritative International Tree-Ring Data Bank (ITRDB) collection.

Limitations

• Dataset is temporally stale, with a last update date of 1986.
• Specific sample size (number of tree cores) and measurement details are unknown.
• Geographic coverage is limited to a single site (Robinson Mountain, Arizona).
