Swiss Tree Ring Chronology from La Gahna Copera

Tree ring width data from the La Gahna Copera site in Switzerland, Western Europe. The chronology covers 43 years from 49 to 7 calendar years before present. This paleoclimatology study is archived by NOAA's National Centers for Environmental Information.

Use Cases

• Calibrating radiocarbon dating curves using the tree-ring chronology as a temporal reference.
• Reconstructing past temperature or precipitation anomalies by analyzing inter-annual tree-ring width variations.
• Studying regional climate events in Western Europe during the period 49-7 years BP through proxy tree-ring data.
• Comparing this Swiss chronology with other European tree-ring series to identify synoptic climate patterns.

Strengths

• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
• Covers a specific 43-year time period (49-7 years BP) for a single site.

Limitations

• Very small temporal coverage of only 43 years limits long-term trend analysis.
• Geographic scope is limited to a single site in Switzerland, reducing regional representativeness.
• Data is temporally stale, last updated in 1999, potentially lacking modern re-calibrations.
