Swiss Tree-Ring Chronology from 47 to -45 BP

NOAA/WDS Paleoclimatology archives a tree-ring dataset from the Boulex site in Switzerland. The chronology covers a 92-year period from 47 to -45 calendar years before present. This data is maintained by the NOAA National Centers for Environmental Information and was last updated in 1995.

Use Cases

• Calibrate climate models by comparing tree-ring width chronologies with instrumental temperature records.
• Reconstruct annual growing season conditions for Western Europe using the dated tree-ring series.
• Analyze the frequency of climatic extremes, such as cold or dry years, within the 92-year chronology.
• Correlate the Swiss tree-ring data with other regional proxy records to validate climate signals.

Strengths

• Data originates from the authoritative NOAA World Data Service for Paleoclimatology.
• Provides a precisely dated 92-year chronology for a specific geographic location in Switzerland.

Limitations

• The dataset is temporally stale, with a last documented update in 1995.
• The sample size and number of individual tree cores used are unknown, limiting statistical assessment.
• Geographic coverage is limited to a single site in Switzerland, reducing regional representativeness.
