Arkansas Tree Ring Chronology For Paleoclimate Reconstruction

NOAA/WDS Paleoclimatology archives a tree ring chronology dataset from the Dragover Takeout site in Arkansas, USA. The data provides annual growth measurements covering a period from 188 to -41 calendar years before present. This study was published by NOAA National Centers for Environmental Information.

Use Cases

• Calibrating climate models using tree ring width as a proxy for past temperature and precipitation in Arkansas.
• Analyzing growth anomaly patterns in the tree ring chronology to identify historical drought or wet periods.
• Cross-dating the tree ring series with other regional chronologies to validate the temporal coverage from 188 to -41 BP.

Strengths

• Data originates from the authoritative NOAA National Centers for Environmental Information.
• Temporal coverage spans 229 years (from 188 to -41 BP).

Limitations

• The dataset's last documented update was in 1991, indicating potential staleness.
• Specific sample size, geographic precision, and measurement parameters are not provided in the summary.
