Swiss Tree Ring Chronology for Paleoclimate Reconstruction

NOAA's World Data Service for Paleoclimatology archives this tree ring dataset from the Chasseral NE North site in Switzerland. The data provides a chronology covering 135 years, from 111 to -24 calendar years before present, for climate reconstruction studies. The National Centers for Environmental Information (NCEI) maintains this archived study, which was last updated in 1974.

Use Cases

• Calibrating climate proxy models using the tree ring width series to infer past temperature or precipitation anomalies.
• Analyzing growth anomaly patterns within the 135-year chronology to identify extreme historical climate events.
• Cross-dating and validating other regional tree ring chronologies using the established Schweingruber series from this site.
• Studying long-term forest growth trends in Western Europe by examining the ring width parameter over the covered period.

Strengths

• Chronology covers a specific 135-year time period (111 to -24 BP).
• Data is curated and archived by the authoritative NOAA NCEI World Data Service.
• Provides a geographically specific record from the Chasseral site in Switzerland.

Limitations

• Dataset is temporally stale, with a last update date of 1974.
• The specific sample depth (number of tree cores) and measurement parameters are unknown from the description.
• Limited geographic scope to a single site in Switzerland.
