NOAA's World Data Service for Paleoclimatology archives this tree ring dataset from Bannwald Sud, Switzerland. The chronology covers a 104-year period from 74 to -30 calendar years before present. NOAA National Centers for Environmental Information (NCEI) published this data, last updated in 1980.
Use Cases
- Calibrating climate models using the tree ring width parameter as a proxy for past temperature or precipitation.
- Analyzing growth anomalies in the ring width series to identify extreme historical climate events.
- Cross-dating this Swiss chronology (ITRDB SWIT116) with other regional series to validate climate reconstructions.
- Studying forest health trends over the 104-year period using the 'Tanne Gesund' (Fir Healthy) site parameter.
Strengths
- Data spans a specific 104-year period (74 to -30 BP), providing a discrete historical window.
- Archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage is relatively short (104 years) compared to millennial-length tree ring chronologies.
- Data is geographically limited to a single site (Bannwald Sud) in Switzerland.
- The last documented update was in 1980, indicating potential staleness in metadata or curation.
