NOAA NCEI provides a tree-ring chronology for Ponderosa Pine (PIPO) from the Defiance East site in Arizona. The data covers 411 years, from 396 to -15 calendar years before present. This paleoclimatology study was archived by NOAA's World Data Service.
Use Cases
- Reconstruct past precipitation or temperature using annual tree-ring width measurements.
- Calibrate climate models by comparing the tree-ring chronology with known historical climate events.
- Analyze growth anomalies in the Ponderosa Pine series to identify periods of drought or stress.
- Establish a dated master chronology for cross-referencing with other archaeological or geological records in the region.
Strengths
- Covers a 411-year time period from 396 to -15 BP.
- Sourced from NOAA NCEI, an authoritative environmental data center.
Limitations
- Temporal coverage ends at -15 BP, with no recent data for modern climate comparison.
- Sample size and replication statistics for the tree-ring series are unknown.
- Geographic scope is limited to a single site in Arizona.
