168-year tree ring chronology from the Mittleri Hellelawald site in Switzerland, covering the period 138 to -30 calendar years before present. The dataset was archived by NOAA's World Data Service for Paleoclimatology and is associated with the Schweingruber study. It was last updated in the NOAA system in 1980.
Use Cases
- Reconstructing past temperature or precipitation anomalies using annual tree ring width measurements.
- Calibrating radiocarbon dates by cross-referencing the tree ring chronology with other proxy records.
- Analyzing long-term climate trends in Western Europe from the 138 to -30 BP time period.
- Studying forest growth responses to historical environmental events captured in the ring parameters.
Strengths
- 168-year continuous chronology providing a climate proxy record.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- The dataset's last known update was in 1980, indicating potential staleness and lack of recent maintenance.
- Specific parameters, measurement methods, and sample depth are unknown without accessing full metadata.
