Swiss Tree Ring Chronology from Bremgartenstrasse

Tree ring data from a site in Western Switzerland, covering a 68-year period from 23 to -45 calendar years before present. This paleoclimatology study is archived by the NOAA National Centers for Environmental Information under its World Data Service. The data was last updated in 1995.

Use Cases

• Calibrating regional tree-ring chronologies using the QURO species code for cross-dating.
• Analyzing climate sensitivity by correlating annual ring-width measurements with temperature or precipitation proxies.
• Reconstructing local environmental events from growth anomalies recorded in the ITRDB SWIT233 series.

Strengths

• Data spans a continuous 68-year period for climate proxy analysis.
• Archived and maintained by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to 68 years, a relatively short period for long-term climate reconstruction.
• Data is temporally stale, with a last update recorded in 1995.
