Arizona tree ring width measurements from Ponderosa Pine (PSME) provide a paleoclimate record. The chronology covers 376 years, from 340 to -36 calendar years before present. NOAA National Centers for Environmental Information archived this dataset in 1986.
Use Cases
- Reconstruct historical precipitation patterns in Arizona using annual tree ring width as a proxy.
- Calibrate climate models by comparing the tree ring chronology with other regional paleoclimate records.
- Analyze long-term growth trends and environmental stress in Ponderosa Pine forests from the ring width time series.
Strengths
- Chronology spans 376 years, providing a multi-century climate record.
- Data is archived and curated by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, last updated in 1986, and may lack modern analytical refinements.
- Geographic scope is limited to a single site in Arizona, reducing generalizability.
- Sample size and replication details for the underlying tree cores are unknown.
