Swiss Tree-Ring Chronology from Les Breuleux (142 to -43 BP)

Tree-ring width measurements from Les Breuleux, Switzerland, provide a climate proxy record covering a 185-year period from 142 to -43 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information (NCEI) World Data Service for Paleoclimatology. This specific study was last updated in 1993.

Use Cases

• Reconstruct past temperature or precipitation anomalies by calibrating tree-ring width series against instrumental climate data.
• Analyze growth patterns and extreme narrow rings to identify years of significant environmental stress like drought or cold.
• Cross-date this chronology with other regional tree-ring datasets to validate and extend climate reconstructions for Western Europe.
• Study the frequency of climatic events by examining the time-series of ring-width indices over the 185-year period.

Strengths

• Covers a specific 185-year time period (142 to -43 BP) for climate analysis.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Provides a geographically localized record for Switzerland, Western Europe.

Limitations

• The dataset is temporally stale, with a last update date of 1993.
• The total number of tree cores or samples is unknown, limiting assessment of statistical robustness.
• Specific measurement parameters and metadata details require external review.
