Tree ring data from the Beaver Creek Watershed in Arizona spans a period from 222 to -35 calendar years before present. The dataset is archived by NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. It was last updated in 1985.
Use Cases
- Analyze annual tree ring width variations to reconstruct past climate conditions like precipitation or temperature.
- Cross-date the chronology with other regional tree ring series to validate historical climate events.
- Calibrate the tree ring time series against known historical periods to extend climate reconstructions.
Strengths
- Time series coverage spans 257 calendar years, from 222 to -35 BP.
- Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.
Limitations
- The dataset's temporal coverage ends at -35 BP (approximately 35 years ago), limiting analysis of very recent periods.
- Data was last updated in 1985, indicating it may not reflect modern methodological standards or corrections.
- Specific parameters, measurements, and sample counts are not provided in the available description.
