Austrian Tree Ring Chronology from 346 to 22 BC

A tree-ring chronology from Obergurgl, Austria, covering Western Europe. The dataset contains parameters for dendrochronological analysis, created by Giertz and archived by NOAA NCEI. Its temporal coverage spans from 346 to 22 calendar years before present.

Use Cases

• Reconstruct past temperature or precipitation anomalies from tree-ring width parameters for the Alpine region.
• Calibrate climate models by comparing the tree-ring chronology with other proxy records for the period 346-22 BC.
• Analyze growth patterns and extreme events recorded in the tree-ring parameters to identify historical droughts or cold periods.

Strengths

• Time series covers a 324-year period (346 to 22 BC).
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.

Limitations

• The dataset's last update was in 1972, indicating potential methodological staleness.
• Specific row count, column details, and measurement parameters are not provided in the input.
