Tree ring width measurements from the Peachtree Bottoms site in Texas provide a paleoclimate record. The dataset covers a 323-year period from 280 to 43 calendar years before present. NOAA National Centers for Environmental Information (NCEI) archived this study, which was last updated in 1993.
Use Cases
- Reconstruct past precipitation or temperature anomalies using the tree ring width time series.
- Calibrate regional climate models by comparing the tree ring chronology with known historical climate periods.
- Analyze the frequency of drought events in Texas during the period from 280 to 43 BC.
- Study the growth response of the sampled tree species to environmental stressors recorded in the ring data.
Strengths
- Covers a 323-year time period from 280 to 43 calendar years BP.
- Geographically specific to a site in Texas, United States.
Limitations
- Data is temporally stale, with a last update recorded in 1993.
- Sample size and replication statistics for the tree ring cores are unknown.
- The dataset's geographic scope is limited to a single site in Texas.
