NOAA's Paleoclimatology archive provides a tree ring chronology from Arizona, United States. The data covers a 329-year period from 308 to 21 calendar years before present. It was published by the NOAA National Centers for Environmental Information under the World Data Service.
Use Cases
- Reconstruct past climate conditions like precipitation or temperature from tree ring width measurements.
- Calibrate radiocarbon dating or other chronological methods using the established tree ring time series.
- Analyze growth patterns and environmental stress events recorded in the tree ring parameters for the Ponderosa Pine (PIPO) species.
- Compare this local Arizona chronology with other regional tree ring datasets to study spatial climate patterns.
Strengths
- Data spans 329 years of historical coverage (308 to 21 BC).
- Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
- Provides a geographically specific record for Arizona, USA.
Limitations
- Temporal coverage ends 21 years before present, lacking modern data.
- Sample size and replication statistics for the tree ring series are unknown.
- The dataset metadata indicates a last update date of 1971, suggesting it is a static archival record.
