Swiss Tree Ring Chronology From 158 to -24 BP

NOAA/WDS Paleoclimatology archives a tree ring dataset from the Schweingruber - Riederalp Vs Aletschwald study in Switzerland. The data provides a chronology covering the period from 158 to -24 calendar years before present. This record is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Calibrating radiocarbon dating curves using the tree ring chronology as a temporal reference.
• Reconstructing past summer temperatures in the Alps by analyzing ring-width measurements.
• Investigating climate anomalies and volcanic events around the year 0 BP through growth pattern anomalies.
• Comparing this Alpine chronology with other ITRDB series (e.g., ITRDB SWIT140) for regional climate signal analysis.

Strengths

• Chronology spans 182 years, from 158 to -24 BP, providing a multi-century record.
• Data is part of the authoritative International Tree-Ring Data Bank (ITRDB) collection under NOAA/NCEI.

Limitations

• Dataset is temporally stale, with a last recorded update in 1974.
• Specific sample size, measurement parameters, and replication statistics are unknown from the provided metadata.
