Tree ring width data from Lake Eufaula, Oklahoma, covering the period from 205 to -30 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. It was last updated in the NCEI system in 1980.
Use Cases
- Reconstruct past precipitation or drought indices for Oklahoma using the tree ring width time-series.
- Calibrate the tree ring chronology against other regional paleoclimate proxies for the period 205 to -30 BP.
- Analyze growth anomalies in the tree ring record to identify extreme climatic events in pre-modern North America.
Strengths
- Time series spans 235 years from 205 to -30 calendar years before present.
- Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
