Swiss Tree Ring Chronology from 413 to 45 BC

NOAA/WDS Paleoclimatology archives a tree ring dataset from Obersaxen, Switzerland. The chronology covers 458 years, from 413 to 45 BC, for climate reconstruction studies. NOAA National Centers for Environmental Information (NCEI) published this data, last updated in 1995.

Use Cases

• Reconstruct past temperature anomalies by calibrating tree ring width measurements against instrumental records.
• Analyze climate periodicity and extreme events from the 458-year tree ring chronology time series.
• Validate regional climate model simulations for the Alpine region using the proxy data point.
• Cross-date archaeological wood samples from Western Europe using the established tree ring sequence.

Strengths

• Covers a 458-year time period (413 to 45 BC) for long-term trend analysis.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last update recorded in 1995.
• Limited geographic scope to a single site (Obersaxen, Switzerland).
• Unknown sample size (number of tree cores or series) limits statistical confidence.
