Mogollon Rim Tree Ring Chronology from 357 to -15 BP

Tree ring width measurements from ponderosa pine (PSME) trees at the Mogollon Rim site in Arizona. The chronology covers 372 years, from 357 to -15 calendar years before present. It was archived by the NOAA National Centers for Environmental Information under its Paleoclimatology program.

Use Cases

• Reconstruct past drought indices by analyzing annual tree ring width variations.
• Calibrate climate models using the 372-year tree ring chronology as a proxy record.
• Study forest growth responses to climate events using the species-specific (PSME) measurements.
• Compare this site's chronology with other ITRDB records for regional climate analysis.

Strengths

• Chronology spans 372 specific years (357 to -15 BP).
• Data is part of the authoritative International Tree-Ring Data Bank (ITRDB).

Limitations

• Sample size (number of tree cores) is not provided.
• The most recent data point is from 15 years before present (1965), indicating no modern updates.
• Geographic coverage is limited to a single site in Arizona.
