Swiss Tree Ring Chronology from 44 to -47 Years BP

Tree ring width measurements from a site in Switzerland provide a 91-year chronology for paleoclimate reconstruction. The data covers the period from 44 to -47 calendar years before present, indicating it spans years around the present era. This archived study was produced by the NOAA National Centers for Environmental Information and last updated in 1997.

Use Cases

• Calibrating climate models by correlating tree ring width variations with known historical temperature or precipitation records.
• Reconstructing past environmental conditions for Western Europe using the Swiss tree ring chronology as a proxy.
• Analyzing growth anomaly years within the 91-year series to identify extreme climate events like droughts or cold periods.

Strengths

• Data spans a 91-year chronology from 44 to -47 years BP.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Provides a geographically specific record for Switzerland, Western Europe.

Limitations

• Temporal coverage is relatively short for long-term climate trend analysis.
• Data is from a single site (Muehletaler Halde), limiting regional representativeness.
• The dataset was last updated in 1997, indicating potential staleness in metadata or availability.
