Swiss Tree Ring Chronology from 40 to -41 BP

NOAA's World Data Service for Paleoclimatology archives a tree ring chronology from the Frischenez site in Switzerland. The data covers a period from 40 to -41 calendar years before present (BP), indicating it spans across the year zero. This dataset was published by NOAA NCEI and last updated in 1991.

Use Cases

• Calibrating radiocarbon dating curves using the tree-ring width series as a reference chronology.
• Reconstructing past temperature or precipitation anomalies in Western Europe from the ring-width parameter.
• Analyzing growth patterns and potential environmental stressors for the species recorded at the Frischenez site.
• Comparing this Swiss chronology (ITRDB SWIT242) with other European tree-ring datasets to identify regional climate signals.

Strengths

• Data is archived and curated by NOAA's authoritative World Data Service for Paleoclimatology.
• Provides a specific, dated chronology from 40 to -41 BP for a defined geographic location in Switzerland.

Limitations

• The dataset's last update was in 1991, potentially lacking modern methodological refinements.
• The small temporal span of approximately 81 years limits analysis of long-term climate trends.
• No column details or sample data are provided, hindering immediate assessment of data structure and variables.
