Swiss Tree Ring Chronology from Lauperswil Dürsrüti

Tree ring width data from Switzerland provides a climate proxy record spanning 226 years, from 186 to -40 calendar years before present. The dataset is archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology. The data was last updated in the system in 1990.

Use Cases

• Reconstruct historical temperature or precipitation anomalies in Switzerland using the tree ring width chronology.
• Calibrate the tree ring series against known climate events within its 226-year temporal coverage.
• Analyze growth patterns and potential disturbances in the Lauperswil Dürsrüti forest site over centuries.
• Compare this Swiss tree ring chronology with other European records to assess regional climate coherence.

Strengths

• Time series covers a 226-year period (186 to -40 BP).
