Tree Ring Chronology from Tsegi Point Road in Arizona (460 to -22 BP)

Tree ring width measurements from a site in Arizona provide a 482-year climate proxy record. The data was archived by NOAA's National Centers for Environmental Information under its World Data Service for Paleoclimatology. This specific chronology was last updated in the NOAA system in 1972.

Use Cases

• Reconstruct past precipitation or drought indices by analyzing annual tree ring width variations.
• Calibrate and validate climate models using the 482-year proxy record of environmental conditions.
• Cross-date archaeological wood samples from the region using the established tree ring chronology.
• Study the frequency of extreme climatic events in Arizona over nearly five centuries.

Strengths

• 482-year temporal coverage from 460 to -22 calendar years before present.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1972, indicating it may not reflect more recent methodological standards.
• Geographic coverage is limited to a single site (Tsegi Point Road) in Arizona.
• Specific measurement parameters, sample depth, and metadata details are not provided in the basic description.
