Swiss Tree Ring Chronology From 46 to 29 BC

Tree ring width measurements from Switzerland provide a 75-year paleoclimate record for Western Europe. The data was archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. This specific chronology was last updated in the NOAA system in 1979.

Use Cases

• Reconstruct annual temperature or precipitation anomalies for Western Europe using the tree ring width parameter.
• Calibrate and validate climate model simulations for the 1st century BC using the dated chronology from 46 to 29 BC.
• Analyze the frequency of climatic extremes or growth suppression events within the 75-year Swiss record.
• Cross-date this chronology (ITRDB SWIT152) with other European tree ring series to build a wider regional climate network.

Strengths

• Data covers a specific 75-year period from 46 to 29 BC, providing a snapshot of ancient climate.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology, ensuring archival stability.

Limitations

• The record is short, spanning only 75 years, limiting analysis of long-term climate trends.
• Data is geographically limited to a single site in Switzerland, reducing regional representativeness.
• The last metadata update was in 1979, indicating the core data has not been recently revised.
