Swiss Tree Ring Chronology from 152 to -46 BP

Tree ring width measurements from the Unter Hubel site in Switzerland, Western Europe. The chronology covers a period from 152 to -46 calendar years before present. This paleoclimatology study is archived and maintained by NOAA's National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width time-series.
• Calibrate climate models by comparing the tree ring chronology with instrumental records for overlapping periods.
• Analyze growth patterns and extreme events (e.g., volcanic winters) within the 198-year time span covered by the data.
• Cross-date this Swiss chronology (ITRDB SWIT306) with other European tree ring datasets to validate regional climate signals.

Strengths

• 198-year continuous tree ring chronology providing a multi-century climate proxy.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at -46 BP (46 BC), lacking more recent centuries for comparison with modern climate.
• Single geographic location (Switzerland) limits representativeness for broader regional analysis.
• Data record was last updated in 1996, potentially missing newer methodological refinements.
