Austrian Tree Ring Chronology from 161 to 24 BCE

161 to 24 BCE tree ring data from the Obergurgl region of Austria, Western Europe, provides a paleoclimate proxy. The dataset is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. This study was published in 1974.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width time-series.
• Calibrate climate models using the high-resolution annual proxy data from 161 to 24 BCE.
• Study ecological responses to historical climate events using the tree ring growth record.
• Perform cross-dating with other regional chronologies using the standardized ring-width index.

Strengths

• Covers a 138-year period (161 to 24 BCE) providing a continuous annual-resolution record.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1974, indicating potential methodological staleness.
• Limited geographic scope to a single site (Obergurgl, Austria).
• Unknown sample size (number of tree cores) and measurement precision.
