Swiss tree ring data from the Chasseral site, covering 128 years from 91 to -37 calendar years before present. The dataset is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1987. It is associated with the NCEI study type 'Tree Ring'.
Use Cases
- Reconstruct historical temperature or precipitation anomalies for Western Europe using tree ring width as a proxy.
- Calibrate climate models by comparing the tree ring chronology against other paleoclimate records for the period 91 to -37 BP.
- Analyze growth patterns in the FASY/ITRDB SWIT220 series to identify extreme climatic events like droughts or cold periods.
- Perform cross-dating with other regional tree ring chronologies to validate and extend the climate record.
Strengths
- Covers a 128-year time period (91 to -37 BP) for climate analysis.
- Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage is limited to a specific 128-year window, not continuous to present day.
- Data is geographically focused on a single site (Chasseral, Switzerland), limiting regional generalization.
- The dataset was last updated in 1987, indicating potential staleness in metadata or collection methods.
