Tree Ring Chronology from Athens, Georgia (129 to -37 BP)

NOAA/WDS Paleoclimatology archives a tree-ring dataset from Athens, Georgia, United States. The data provides a chronology covering the period from 129 to -37 calendar years before present (BP). It was contributed by Grissino-Mayer and last updated in the NOAA NCEI system in 1987.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using tree-ring width measurements.
• Calibrate and validate climate models for the southeastern US region using the dated chronology.
• Analyze growth anomalies in the tree-ring series to identify historical drought or extreme weather events.
• Compare this chronology with other ITRDB (International Tree-Ring Data Bank) series for regional climate signal analysis.

Strengths

• Chronology spans 166 years (129 to -37 BP), providing a multi-century climate record.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1987, indicating potential staleness in metadata or availability.
• Specific sample size, measurement parameters, and replication statistics are not provided in the basic description.
• Geographic coverage is limited to a single site in Athens, Georgia, limiting broad spatial analysis.
