Tree ring width measurements from the Arlenwald South site in Arosa, Switzerland, provide a climate proxy record. The chronology spans 190 years, from 165 to -25 calendar years before present. The dataset was produced by Schweingruber and archived by NOAA's World Data Service for Paleoclimatology, with a last recorded update in 1975.
Use Cases
- Calibrate climate models using the tree ring width time series as a proxy for historical temperature or precipitation.
- Analyze growth anomaly patterns in the ring width record to identify extreme climatic events like droughts or cold periods.
- Cross-date and validate other tree ring chronologies from the Western European region using this established reference series.
- Study long-term ecological trends in a Swiss Alpine forest ecosystem through the annual growth measurements.
Strengths
- 190-year continuous chronology from 165 to -25 BP
- Geographically precise data from a single site in Arosa, Switzerland
Limitations
- Temporal coverage is relatively short for paleoclimate studies
- Data is from a single site, limiting regional representativeness
- Last update was in 1975, indicating potential staleness in metadata or access methods
