Tree ring width measurements from Switzerland provide a 101-year annual climate record. The NOAA National Centers for Environmental Information archives this paleoclimatology study for Western Europe. Data was last updated in the repository in 1991.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree ring width time-series.
- Calibrate radiocarbon dating curves by aligning the tree ring chronology with known calendar years BP.
- Analyze growth response to extreme events by examining ring width deviations within the 101-year sequence.
- Compare this Swiss chronology (ITRDB SWIT363) with other European tree ring datasets for regional climate patterns.
Strengths
- Covers a specific 101-year period from 60 to 41 BC.
- Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage is limited to a single century, preventing long-term trend analysis.
- Data is geographically restricted to a single site in Switzerland, limiting spatial representativeness.
- The record was last updated in 1991, indicating no recent revisions or quality reassessments.
