Tree ring width measurements from a wetland site in Georgia provide a 124-year climate record. The data, archived by NOAA's World Data Service for Paleoclimatology, was contributed by the J.W. Jones Ecological Research Center. This paleoclimate study was last updated in 1995.
Use Cases
- Reconstruct past precipitation or temperature anomalies by analyzing the annual tree ring width series.
- Calibrate the tree ring chronology against other regional paleoclimate proxies using its documented time period.
- Study the response of wetland tree species to climatic events during the documented period from 79 to 45 BCE.
Strengths
- Data spans 124 consecutive years (79 to 45 BCE), providing a continuous climate proxy.
- Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage is limited to a specific 124-year window, restricting analysis of long-term trends.
- The dataset's last documented update was in 1995, potentially lacking modern reanalysis or corrections.
- Geographic scope is restricted to a single site in Georgia, USA, limiting regional generalization.
