NOAA/WDS Paleoclimatology archives a tree ring chronology dataset from Walnut Canyon National Monument in Arizona. The data provides a time series of tree ring parameters covering the period from 503 to -16 calendar years before present. This study was contributed to the NOAA National Centers for Environmental Information.
Use Cases
- Reconstruct historical climate variables like precipitation or temperature from the tree ring width series.
- Calibrate climate models by comparing the tree ring chronology with instrumental records for the Arizona region.
- Analyze growth anomalies in the Pinus ponderosa (PIPO) ring data to date past ecological disturbances.
- Study long-term environmental trends by examining the full 519-year span of the tree ring time series.
Strengths
- Time series covers a 519-year period (503 to -16 BP), providing long-term context.
- Data is archived and curated by the authoritative NOAA National Centers for Environmental Information.
Limitations
- The dataset's last recorded update was in 1966, indicating potential staleness in metadata or curation.
- Specific sample size, measurement parameters, and data formats are not provided in the description.
