Tree ring width measurements from ponderosa pine (PSME) trees in the Santa Rita Mountains of Arizona. The data provides a 321-year chronology from 305 BC to 16 AD for paleoclimate reconstruction. This study is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1966.
Use Cases
- Reconstruct historical precipitation or drought indices using annual tree ring width as a proxy.
- Calibrate regional climate models by comparing the tree ring chronology with known climatic events.
- Analyze growth anomalies in the ring width series to identify volcanic eruptions or other disturbances.
- Establish cross-dating references for other tree ring studies in the Arizona region.
Strengths
- 321-year continuous chronology from 305 BC to 16 AD.
- Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.
Limitations
- The dataset's last update was in 1966, indicating potentially outdated collection and processing methods.
- Specific sample depth, measurement statistics, and site replication details are not provided in the input.
