Swiss Tree Ring Chronology from 107 to -27 BP

Tree ring width chronology data from Roggwil, Switzerland, covering 134 calendar years from 107 to -27 BP. The dataset is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. It was originally published in 1977.

Use Cases

• Calibrating climate proxy models by analyzing the correlation between tree ring width series and temperature/precipitation records.
• Reconstructing past climate anomalies in Western Europe using the dated tree ring chronology as a primary source.
• Cross-dating other regional tree ring collections by matching patterns in the ring width time series.
• Studying local environmental events by examining growth suppression or release signals within the ring sequence.

Strengths

• Time series covers 134 calendar years (107 to -27 BP), providing a discrete historical snapshot.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset is small, containing only a single chronology from one site in Switzerland.
• Data is temporally stale, with a last update recorded in 1977, limiting modern analytical integration.
