Arizona Ponderosa Pine Tree Ring Chronology from Cross Canyon

Tree ring width measurements from 339 to -22 calendar years before present provide a paleoclimate record for Arizona. This dendrochronological dataset is archived by NOAA's World Data Service for Paleoclimatology. The data was last updated in the NOAA system in 1972.

Use Cases

• Reconstruct past precipitation and temperature anomalies by analyzing annual tree ring width variations.
• Calibrate radiocarbon dating or other chronological methods using the established tree ring chronology.
• Model climate-growth relationships for Ponderosa pine (PIPO) in the Cross Canyon region of Arizona.
• Compare this site chronology with others from the ITRDB AZ090 network to assess regional climate signals.

Strengths

• Chronology spans 361 years (339 to -22 BP), offering a multi-century climate record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data appears temporally stale, with a last update date of 1972, potentially missing modern methodological revisions.
• The sample size, geographic representativeness, and replication depth of the underlying tree cores are unknown.
