NOAA's World Data Service for Paleoclimatology archives this tree ring dataset from Haslenau, Switzerland. The data provides a chronology covering 4 to 41 calendar years before present, used for climate reconstruction. The dataset was published by NOAA NCEI and last updated in 1991.
Use Cases
- Calibrating climate models by comparing the tree ring width chronology with instrumental temperature and precipitation records.
- Reconstructing past temperature or drought indices for Western Europe using the dated ring width series.
- Analyzing growth anomalies in the chronology to identify volcanic eruption impacts or other short-term climate forcings.
- Cross-dating other regional tree ring collections using the established master chronology from this site.
Strengths
- Data originates from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
- Provides a precisely dated annual-resolution chronology spanning 45 years.
Limitations
- Temporal coverage is limited to a short 45-year period (4 to 41 BP).
- Data is geographically limited to a single site (Haslenau, Switzerland).
- The dataset is temporally stale, with a last update date of 1991.
