NOAA/WDS Paleoclimatology archives a tree ring chronology dataset from the Oak Creek site near Apache Reservoir in Arizona. The data covers a period from 255 to -21 calendar years before present. This study was contributed to the NOAA National Centers for Environmental Information's World Data Service for Paleoclimatology.
Use Cases
- Reconstruct past climate variables like precipitation or temperature using tree ring width measurements.
- Calibrate and validate climate models for the Arizona region with the 276-year chronology.
- Analyze growth anomalies in the PIED (Pinus edulis) species to identify historical drought events.
- Cross-date tree ring sequences from the ITRDB AZ078 site with other regional chronologies.
Strengths
- Data spans 276 calendar years, from 255 to -21 BP.
- Part of the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage is relatively short for some paleoclimate studies.
- Geographic scope is limited to a single site in Arizona.
- Data record was last updated in 1971, indicating potential staleness.
