Swiss Tree Ring Chronology from 97 to -45 BP

NOAA/WDS Paleoclimatology archives a tree ring dataset from the Le Communal de la Sagne site in Switzerland. The data provides a chronology covering 142 years, from 97 to -45 calendar years before present. It was contributed to the International Tree-Ring Data Bank and last updated in 1995.

Use Cases

• Reconstruct past temperature or precipitation anomalies using tree ring width measurements.
• Calibrate climate models by comparing the tree ring chronology with other proxy records for the period.
• Analyze growth patterns to identify extreme environmental events like droughts or cold periods within the 142-year span.
• Study ecological responses in a Swiss forest ecosystem to climate variability before present.

Strengths

• Data spans a specific 142-year time period from 97 to -45 BP.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology and the ITRDB.

Limitations

• Temporal coverage is relatively short for long-term climate trend analysis.
• Data is geographically limited to a single site in Switzerland, limiting regional generalizations.
• The dataset was last updated in 1995, indicating potential staleness in metadata or availability.
