Swiss Tree Ring Chronology From 98 to -45 BP

Swiss tree ring data provides a chronology for environmental reconstruction. The dataset covers 143 years, from 98 to -45 calendar years before present. It was archived by NOAA's World Data Service for Paleoclimatology and last updated in 1995.

Use Cases

• Calibrating regional climate models using tree ring width as a proxy for past temperature or precipitation.
• Analyzing growth anomaly patterns across the 143-year chronology to identify extreme historical events.
• Cross-dating this chronology with other European tree ring series to validate temporal alignment.

Strengths

• Data spans 143 calendar years, providing a multi-century environmental record.
• Sourced from NOAA's authoritative World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to a specific 143-year period in the distant past.
• Data was last updated in 1995, indicating potential staleness in metadata or documentation.
