Tree Ring Chronology for Arkansas Climate Reconstruction

NOAA/WDS Paleoclimatology archives a tree-ring chronology dataset from the Mayberry Slough and Watson Lake sites in Arkansas. The data provides a time series covering 787 years, from 750 to -37 calendar years before present. It was published by the NOAA National Centers for Environmental Information in 1987.

Use Cases

• Reconstruct past temperature or precipitation using the tree-ring width chronology as a climate proxy.
• Analyze long-term drought frequency and severity in Arkansas by examining the annual resolution ring-width data.
• Calibrate regional climate models by comparing the tree-ring derived climate indices with instrumental records.
• Study the climate signal embedded in the tree-ring parameters from the specific Arkansas study sites.

Strengths

• Provides a high-resolution annual climate proxy record spanning 787 years.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.

Limitations

• Dataset is temporally stale, with a last documented update in 1987.
• Geographic coverage is limited to two specific sites in Arkansas, USA.
• The exact parameters and sample depth (row count) are unspecified in the provided metadata.
