German Tree Ring Chronology from 108 to -48 Years BP

NOAA/WDS Paleoclimatology archives a tree ring chronology dataset from Lausanne, Switzerland, associated with the ITRDB site SWIT294. Data coverage spans from 108 to -48 calendar years before present, with a geographic focus on Germany in Western Europe. The dataset was published by NOAA National Centers for Environmental Information and last updated in 1998.

Use Cases

• Calibrating climate models using tree ring width as a proxy for past temperature or precipitation in Germany.
• Analyzing growth anomaly patterns within the chronology to identify extreme climate events like droughts.
• Cross-dating this SWIT294 chronology with other regional series to validate and extend climate reconstructions.
• Studying long-term forest growth trends in Western Europe from 108 to -48 years BP.

Strengths

• Temporal coverage spans 156 years, from 108 to -48 calendar years before present.
• Data is archived and curated by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Dataset is temporally stale, with a last update recorded in 1998.
• Specific sample size, measurement parameters, and replication depth are unknown from the provided metadata.
• Geographic focus is listed as Germany but sourced from a Swiss (Lausanne) archive, requiring verification of exact site location.
