Swiss Tree Ring Chronology From Haslenau (18 to -41 BP)

NOAA/WDS Paleoclimatology archives a tree-ring chronology from Haslenau, Switzerland. The dataset covers the period from 18 to -41 calendar years before present, created by Bräker and maintained by NOAA National Centers for Environmental Information. The record was last updated in 1991.

Use Cases

• Calibrate climate models using tree-ring width as a proxy for past temperature or precipitation in Switzerland.
• Analyze growth anomaly years within the 59-year chronology to identify extreme climatic events.
• Cross-date this ITRDB SWIT251 series with other regional chronologies to validate climate signals.
• Study forest growth responses to environmental changes during the period covered by the data.

Strengths

• Data originates from the authoritative NOAA World Data Service for Paleoclimatology.
• Chronology covers a 59-year time period (18 to -41 BP).
• Geographic location is precisely specified as Haslenau, Switzerland, Western Europe.

Limitations

• Temporal coverage is limited to 59 years, providing a short snapshot for analysis.
• The dataset was last updated in 1991, indicating potential staleness in metadata or access methods.
• Specific measured parameters (e.g., ring width, density) and sample depth are not detailed in the provided description.
