Swiss Tree Ring Chronology from 27 to -41 Years Before Present

Tree ring width measurements from a site in Switzerland, Western Europe, provide a chronology covering 68 years from 27 to -41 calendar years before present. The data is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. This specific study was last updated in 1991.

Use Cases

• Calibrating radiocarbon dating curves using the tree ring chronology as a reference time series.
• Analyzing year-to-year climate variability by correlating ring width measurements with temperature or precipitation proxies.
• Reconstructing local environmental conditions for Western Europe during the specified 68-year period before present.
• Comparing this Swiss chronology with other European tree ring datasets to identify regional climate patterns.

Strengths

• Chronology spans a defined 68-year period from 27 to -41 BP.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service.

Limitations

• The dataset covers a relatively short temporal span of 68 years.
• Data is from a single geographic location in Switzerland, limiting regional analysis.
• The last update was in 1991, indicating potential staleness in metadata or access methods.
