530 to -37 calendar years before present of tree ring width measurements from ponderosa pine (PIPO) trees in Walnut Canyon, Arizona. The dataset is part of the NOAA/WDS Paleoclimatology archive, contributed by Graybill and managed by NOAA National Centers for Environmental Information. It was archived in 1987.
Use Cases
- Reconstruct past climate variables like precipitation or temperature by analyzing annual tree ring width variations.
- Establish a dated chronology for archaeological or geological studies using the tree ring time series.
- Study long-term ecological growth patterns and responses of ponderosa pine to environmental stressors in Arizona.
- Calibrate or validate climate models using the high-resolution proxy data spanning over 500 years.
Strengths
- Time series spans 567 calendar years (from 530 to -37 BP), providing multi-century coverage.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Dataset is temporally stale, with a last documented update in 1987.
- Specific sample size, measurement parameters, and data granularity are not provided in the description.
