Tree ring width data from the Magness Barn site in Arkansas provides a 260-year climate record from 352 to 92 calendar years before present. The dataset is part of the NOAA NCEI World Data Service for Paleoclimatology and is associated with the International Tree-Ring Data Bank. It was archived by the NOAA National Centers for Environmental Information.
Use Cases
- Calibrate climate models by comparing tree ring width variations against known historical climate proxies.
- Reconstruct annual precipitation or temperature anomalies for Arkansas using the tree ring chronology.
- Analyze the frequency and severity of past drought events in the region from the ring width time series.
- Cross-date archaeological wood samples from the southeastern U.S. using the established tree ring chronology.
Strengths
- Covers a continuous 260-year period from 352 to 92 BP.
- Geographically specific to a single site in Arkansas, USA.
Limitations
- Temporal coverage is limited to a single 260-year snapshot of the past.
- Spatial representation is limited to one location, reducing regional generalizability.
