178 to -29 calendar years before present of tree ring width measurements from the Pierre Avoi site in Switzerland. The dataset is archived by NOAA's World Data Service for Paleoclimatology as part of the Schweingruber collection. It was last updated in the NOAA system in 1979.
Use Cases
- Reconstruct past temperature or precipitation anomalies using annual tree-ring width as a climate proxy.
- Calibrate radiocarbon dating or validate other paleoclimate records by cross-dating the tree-ring chronology.
- Analyze growth response to environmental stressors by examining year-to-year variations in ring-width measurements.
- Study long-term forest dynamics and ecological changes at the Pierre Avoi site over the recorded time span.
Strengths
- Covers a 207-year time period (178 to -29 BP) from a specific geographic location.
- Part of the authoritative NOAA/NCEI World Data Service for Paleoclimatology archive.
- Data is associated with the established Schweingruber collection and ITRDB SWIT130 identifier.
Limitations
- Temporal coverage is relatively short (207 years) compared to other millennial-length tree-ring chronologies.
- Data is geographically limited to a single site (Pierre Avoi) in Switzerland.
- The dataset metadata indicates a last system update in 1979, suggesting potential staleness in documentation or format.
