Old Growth Tree Ring Chronology from Arkansas, 325 to -41 BP

NOAA/WDS Paleoclimatology archives a tree ring dataset from an old growth study in Washington County, Arkansas. The data provides a chronology covering the period from 325 to -41 calendar years before present. This dataset was published by NOAA National Centers for Environmental Information (NCEI) and last updated in 1991.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree ring width chronology.
• Calibrate and validate climate models for the Arkansas region using the dated proxy record.
• Analyze long-term ecological trends in old growth forests from the Washington County site.
• Compare this chronology with other ITRDB (International Tree-Ring Data Bank) series for regional climate signal analysis.

Strengths

• Chronology spans 366 years (325 to -41 BP), providing a multi-century record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, with a last update date of 1991.
• Specific sample depth, measurement statistics, and site details are not provided in the input.
