Swiss Tree Ring Chronology From 82 to -30 BP

NOAA/WDS Paleoclimatology archives a tree-ring dataset from the Bannwald North site in Switzerland. The data provides a chronology covering the period from 82 to -30 calendar years before present. It was contributed by Schweingruber and is managed by NOAA National Centers for Environmental Information.

Use Cases

• Calibrating radiocarbon dates using the tree-ring chronology as a reference series.
• Reconstructing past temperature or precipitation anomalies from ring-width measurements.
• Analyzing growth trends and extreme events (e.g., frost rings) within the 112-year sequence.
• Comparing this Alpine chronology with other European tree-ring networks for spatial climate patterns.

Strengths

• Chronology spans 112 calendar years, providing a continuous environmental record.
• Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1980, potentially lacking modern reanalysis or calibration.
• Specific sample depth, measurement parameters, and raw data formats are not provided in the description.
• Geographic coverage is limited to a single site (Bannwald North) in Switzerland.
