Tree ring width data from a site in Oklahoma, United States, used for paleoclimate reconstruction. The chronology covers a period from 252 to -30 calendar years before present. Data is archived by NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology.
Use Cases
- Reconstruct past temperature or precipitation levels using the tree ring width time-series.
- Calibrate the chronology against other regional proxy records for climate model validation.
- Analyze growth patterns in the tree ring series to identify periods of drought or favorable climate conditions.
Strengths
- Chronology spans 282 years, from 252 to -30 calendar years BP.
- Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Sample size, number of tree cores, and replication statistics are unknown.
- Geographic coverage is limited to a single site at Lake Arbuckle, Oklahoma.
- Data was last updated in 1980, indicating potential staleness in metadata or methods.
