Swiss Tree Ring Chronology from FregeGambarogno

NOAA/WDS Paleoclimatology archives a tree-ring chronology from the FregeGambarogno site in Switzerland. The dataset covers a time period from 30 to -37 calendar years before present. It was published by NOAA National Centers for Environmental Information in 1987.

Use Cases

• Calibrating climate models using tree-ring width as a proxy for past temperature or precipitation in Western Europe.
• Analyzing growth anomaly years within the chronology to identify extreme historical climate events.
• Cross-dating this chronology with other regional tree-ring series to validate and extend climate reconstructions.
• Studying the response of tree growth to environmental conditions during the covered 67-year period.

Strengths

• Data originates from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Provides a clearly defined temporal coverage of 67 calendar years.

Limitations

• The dataset's last update was in 1987, indicating potential staleness relative to modern methods.
• Specific sample size, measurement parameters, and replication statistics are unknown from the description.
• Geographic coverage is limited to a single site in Switzerland.
