Swiss Tree Ring Chronology From 33 to -46 BP

Tree ring data from Isone, Switzerland provides a paleoclimate record spanning 80 years, from 33 to -46 calendar years before present. The dataset was archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology. This study was last updated in 1996.

Use Cases

• Calibrate climate models using tree-ring width as a proxy for past temperature or precipitation in Switzerland.
• Analyze growth anomaly patterns in the time-series to identify extreme climatic events like droughts or cold periods.
• Cross-date this chronology with other regional tree-ring datasets to validate and extend climate reconstructions.

Strengths

• Data covers a continuous 80-year time period from 33 to -46 BP.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to 80 years, a relatively short span for long-term climate trend analysis.
• Data is geographically limited to a single site (Isone, Switzerland), reducing regional representativeness.
• The dataset was last updated in 1996, indicating potential staleness in metadata or curation methods.
