Tree ring width measurements from a healthy fir tree in Roggwil, Switzerland, provide a climate proxy record. The chronology covers 104 years, from 76 to -27 calendar years before present. This archived study was contributed by Schweingruber and is maintained by NOAA's World Data Service for Paleoclimatology, with a last documented update in 1977.
Use Cases
- Calibrating regional climate models by correlating tree ring width variations with temperature and precipitation proxies.
- Reconstructing annual growth conditions for fir trees in Western Europe during a defined 104-year period.
- Establishing a reference chronology for cross-dating other tree ring samples from the Alpine region.
- Analyzing the response of healthy fir trees (Abies alba) to environmental stressors in the pre-Roman era.
Strengths
- Covers a specific 104-year time period (76 to -27 BP).
- Provides a focused record from a single, documented healthy fir tree (Abies alba).
- Archived and curated by the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- Very small sample size, representing a single tree, limiting statistical robustness.
- Data is temporally stale, with no updates recorded since 1977.
- The 'negative' year range (-27 BP) requires careful interpretation of the calendar year timeline.
