Tree ring data from Arizona, United States, covers a 207-year period from 170 to -37 calendar years before present. The dataset is archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology. This paleoclimatology study was last updated in 1987.
Use Cases
- Reconstruct past temperature or precipitation anomalies using annual tree ring width measurements.
- Calibrate climate models by comparing the tree ring chronology with instrumental climate records.
- Analyze long-term climate trends and variability in the North American Southwest over a 207-year period.
- Study the response of Abies concolor (ABCO) tree growth to historical climate events.
Strengths
- 207-year chronology providing a multi-century climate proxy.
- Data is curated and archived by the authoritative NOAA NCEI World Data Service.
Limitations
- Temporal coverage ends at -37 BP, limiting analysis for the most recent millennia.
- Data is from a single site (ITRDB AZ529), limiting spatial representativeness.
- Last update was in 1987, indicating potential staleness in metadata or availability.
