Swiss Tree Ring Chronology From 107 to -46 BP

Tree ring width measurements from Chironico, Switzerland provide a 153-year climate proxy record. The NOAA National Centers for Environmental Information archives this paleoclimatology study under its World Data Service. Data was last updated in the NOAA system in 1996.

Use Cases

• Calibrating regional climate models using tree-ring width as a proxy for past temperature or precipitation.
• Reconstructing annual growth conditions for the Abies alba (ABAL) species in Western Europe.
• Analyzing the frequency of narrow or wide rings to identify extreme climate events like droughts or cold periods.
• Cross-dating this ITRDB SWIT221 chronology with other regional series to validate climate signals.

Strengths

• Covers a 153-year time period from 107 to -46 calendar years BP.
• Geographically specific to a single site in Switzerland, allowing for localized analysis.

Limitations

• Temporal coverage is relatively short for dendrochronological studies, limiting long-term trend analysis.
• Data is archived from 1996, so methodologies and metadata standards may be outdated.
• Unknown sample depth (number of trees) affects the statistical robustness of the chronology.
