273 tree ring width measurements from a single Pinus ponderosa (PIPO) site in Arizona, United States. The chronology spans from 273 to -21 calendar years before present, providing a proxy for past climate conditions. This archived paleoclimatology study is maintained by NOAA's National Centers for Environmental Information.
Use Cases
- Reconstruct past precipitation or temperature anomalies using the tree ring width time-series.
- Calibrate regional climate models by comparing the ring width chronology with known historical climate events.
- Analyze growth patterns and potential climate stressors for Pinus ponderosa in the Salt River Draw region.
- Establish a dated chronology for cross-referencing with other paleoclimate proxies from the southwestern US.
Strengths
- Provides a continuous 294-year time-series of tree ring data.
- Data is archived and curated by NOAA's authoritative World Data Service for Paleoclimatology.
Limitations
- The dataset is derived from a single tree species at one site, limiting geographic representativeness.
- The temporal coverage ends at -21 BP (approximately 1971 CE), lacking recent decades.
