Swiss Tree Ring Chronology from 30 to -39 Years BP

30 to -39 calendar years before present (BP) of tree ring data from the Biglenwald site in Switzerland. The dataset is archived by NOAA's World Data Service for Paleoclimatology as part of their Tree Ring study collection. The data was last updated in the NOAA system in 1989.

Use Cases

• Reconstruct past climate variables like temperature or precipitation by analyzing tree ring width chronology.
• Calibrate radiocarbon dating or other chronological models using the dated tree ring series.
• Study ecological responses to historical climate events in the Swiss Alpine region using the site-specific proxy record.
• Compare this Western European tree ring chronology with other regional datasets to analyze spatial climate patterns.

Strengths

• Covers a 69-year period from 30 to -39 calendar years BP, providing a discrete historical snapshot.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology, ensuring standardized metadata.

Limitations

• The dataset's last known update was in 1989, indicating potential staleness in curation or availability.
• The specific sample size (number of tree cores or series) and measurement parameters are unknown from the description.
• Geographic coverage is limited to a single site (Biglenwald, Switzerland), reducing broad spatial representativeness.
