NOAA/WDS Paleoclimatology archives a tree ring chronology from the Paria Plateau in Arizona. The data provides a proxy climate record spanning 463 years, from 415 to 48 calendar years before present. It was published by NOAA National Centers for Environmental Information in 1998.
Use Cases
- Reconstruct annual precipitation or drought indices for the southwestern US using the tree ring width chronology.
- Calibrate climate models by comparing the proxy temperature record from ring density with instrumental data.
- Analyze the frequency of extreme climatic events, such as megadroughts, within the 463-year time series.
- Study ecological resilience by correlating the growth anomaly series with known historical volcanic or climatic events.
Strengths
- Time series covers a 463-year period (415 to 48 BP).
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, last updated in 1998.
- Geographic coverage is limited to a single site (Paria Plateau, Arizona).
- Specific sample depth, measurement parameters, and potential dating uncertainties are unknown from the provided metadata.
