Swiss Tree Ring Chronology from 33 to -29 BP

NOAA's Paleoclimatology archive provides a tree-ring chronology from Rüti bei Büren, Switzerland, covering a 62-year period from 33 to -29 calendar years before present. The dataset is part of the International Tree-Ring Data Bank (ITRDB) and was contributed by researcher Schweingruber. This record was archived by the NOAA National Centers for Environmental Information in 1979.

Use Cases

• Calibrating radiocarbon dating curves using the tree-ring width series as a reference chronology.
• Reconstructing annual temperature or precipitation anomalies for Western Europe from ring-width measurements.
• Analyzing growth anomaly patterns to identify volcanic eruption events or other short-term climate forcings within the 62-year period.
• Cross-dating archaeological wood samples from the Swiss region by matching ring-width sequences.

Strengths

• Data originates from the authoritative NOAA World Data Service for Paleoclimatology and the ITRDB.
• Covers a specific 62-year period with annual resolution typical of dendrochronology.

Limitations

• Extremely short temporal coverage of only 62 years limits long-term climate trend analysis.
• Geographic scope is limited to a single site in Switzerland, reducing regional representativeness.
• Data is stale, last updated in 1979, and may lack modern metadata standards.
