Tree ring width measurements provide a proxy record for past climate conditions in Arizona, United States. The dataset covers a time period from 330 to 15 calendar years before present (BP). It is archived by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree ring width time-series.
- Calibrate climate models by comparing the tree ring chronology with instrumental records.
- Analyze growth patterns and extreme events within the 345-year temporal coverage of the dataset.
- Study regional climate dynamics by comparing this Arizona chronology with other tree ring records.
Strengths
- Time series spans 345 calendar years (330 to 15 BP)
- Data is curated and archived by the authoritative NOAA NCEI World Data Service
Limitations
- Temporal coverage ends 15 years before present, limiting overlap with modern instrumental records
- Geographic scope is limited to a single location in Arizona
- Sample size and replication statistics for the tree ring series are unknown
