Swiss Tree Ring Chronology from 236 to -26 BP

NOAA/WDS Paleoclimatology archives a tree ring dataset from Krauchthal, Switzerland. The chronology covers a 262-year period from 236 to -26 calendar years before present. This data is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
• Calibrate radiocarbon dating models by cross-referencing the dated tree ring sequence.
• Analyze climate signal strength and persistence over the 262-year time period covered by the series.

Strengths

• Data spans a 262-year period (236 to -26 BP), providing a multi-century climate record.
• Archived and curated by the authoritative NOAA National Centers for Environmental Information.

Limitations

• The dataset's last update was in 1976, indicating potential methodological or metadata staleness.
• Geographic coverage is limited to a single site (Krauchthal, Switzerland), limiting regional representativeness.
• Specific parameters like ring width, density, or measurement counts are not detailed in the provided description.
