Swiss Tree Ring Chronology from 121 to -43 BP

121 to -43 calendar years before present (BP) of tree ring data from the La Grandsonne site in Switzerland, Western Europe. This archived paleoclimatology study is a tree ring chronology available from the NOAA National Centers for Environmental Information (NCEI) under the World Data Service for Paleoclimatology. The data was last updated in the archive on January 1, 1993.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width parameter series.
• Calibrate radiocarbon dates or synchronize regional chronologies using the provided year-by-year index values.
• Study climate extremes and events in Western Europe during the period covered by the La Grandsonne chronology.
• Validate climate model simulations of the past using the proxy climate record derived from tree ring parameters.

Strengths

• Time series covers a 164-year period from 121 to -43 calendar years BP.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's temporal coverage is relatively short for long-term climate trend analysis.
• Data is geographically limited to a single site (La Grandsonne) in Switzerland.
• The archive was last updated in 1993, indicating the core data is not recent.
