Tree ring width measurements from the Arosa GR Rot Tritt North site in Switzerland provide a climate proxy record. The chronology spans 285 years, from 260 to -25 calendar years before present. This archived dataset is maintained by NOAA's World Data Service for Paleoclimatology and was last updated in 1975.
Use Cases
- Reconstruct past temperature or precipitation anomalies by calibrating tree ring width series against instrumental climate records.
- Analyze growth trends and extreme events within the 285-year chronology to identify periods of climatic stress.
- Cross-date and synchronize this tree ring series with other regional chronologies using its year-by-year width measurements.
- Validate regional climate model simulations for the Alps using the high-resolution proxy data from this site.
Strengths
- Chronology spans 285 consecutive years, providing a continuous high-resolution record.
- Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.
- Site-specific geographic location in Switzerland enables precise regional climate analysis.
Limitations
- The dataset is temporally stale, with a last update date of 1975, potentially missing modern analytical refinements.
- The sample size (number of trees/cores) is unknown, limiting assessment of statistical robustness.
- Geographic coverage is limited to a single site in Switzerland, reducing broad spatial representativeness.
