Swiss Tree Ring Chronology from 120 to 40 BC

Tree ring width measurements from the Le Crêt rond site in Switzerland provide a 160-year climate proxy record. The data covers the period from 120 to 40 calendar years before present. This paleoclimatology study was archived by NOAA National Centers for Environmental Information and last updated in 1990.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width time-series.
• Calibrate regional climate models by comparing the ring width chronology with known historical events.
• Analyze growth patterns to identify climatic stress events like droughts within the 160-year record.
• Cross-date this chronology with other European tree ring series to validate temporal coverage.

Strengths

• 160-year continuous time-series from 120 to 40 BP.
• Data originates from the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to a single 160-year period.
• Data was last updated in 1990 and may lack modern methodological revisions.
• Geographic scope is restricted to one site in Switzerland.
