Swiss Tree Ring Chronology from Haslenau for Paleoclimate Study

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

Use Cases

• Calibrating climate models using tree-ring width as a proxy for past temperature or precipitation in Western Europe.
• Analyzing growth anomaly patterns within the 41-18 BP time range to identify extreme historical climate events.
• Cross-dating this Swiss chronology (ITRDB SWIT249) with other regional tree-ring records to validate climate reconstructions.
• Studying the response of tree growth, measured via ring parameters, to known volcanic or solar forcing events within the covered period.

Strengths

• Data is archived and curated by the authoritative NOAA National Centers for Environmental Information (NCEI).
• Provides a clearly defined temporal coverage of 23 years (from 41 to 18 BP) for a specific geographic location.

Limitations

• The dataset is temporally stale, with a last update recorded in 1991, potentially missing modern reanalysis.
• The small temporal window (23 years) limits analysis of long-term climate trends or low-frequency cycles.
• Lack of accessible column details or sample data hinders immediate assessment of data structure and parameters.
