Tree Ring Chronology from Lake Winona, Arkansas (283 to -30 BP)

Tree ring width measurements from Lake Winona, Arkansas, span 313 years from 283 to -30 calendar years before present. The dataset is part of the NOAA/WDS Paleoclimatology collection, specifically the International Tree-Ring Data Bank (ITRDB) series AR027. It was archived by the NOAA National Centers for Environmental Information and last updated in 1980.

Use Cases

• Reconstruct past climate variables like precipitation or temperature using the tree ring width time-series as a proxy.
• Analyze growth patterns and anomalies in the ring width series to identify extreme drought or wet periods in ancient Arkansas.
• Calibrate the tree ring chronology from site AR027 against other regional proxy records to build a composite climate history.
• Use the geographic location and time period coverage to place the site's climate signal within a broader spatiotemporal framework.

Strengths

• Covers a 313-year time period from 283 to -30 calendar years BP.
• Part of the authoritative NOAA Paleoclimatology and ITRDB collections, ensuring standardized metadata.

Limitations

• The dataset was last updated in 1980, indicating potential staleness and lack of recent methodological revisions.
• Specific sample depth, measurement statistics, and climate parameter correlations are not provided in the basic description.
