Swiss Tree Ring Chronology from 114 to -33 Years BP

Tree ring data from the Breitbirch site in Switzerland, Western Europe, covering a 147-year period from 114 to -33 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. This study was published in 1983.

Use Cases

• Reconstruct historical temperature or precipitation anomalies using the tree ring width series.
• Calibrate the chronology against other regional proxy records for climate event validation.
• Analyze growth patterns in the Breitbirch series to identify volcanic or climatic disturbance events.
• Use the dated series as a reference for cross-dating other tree ring samples from Western Europe.

Strengths

• Data spans a specific 147-year period from 114 to -33 years BP.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to a short 147-year window.
• Data is geographically limited to a single site in Switzerland.
• The dataset was last updated in 1983 and may lack modern methodological refinements.
