Swiss Tree-Ring Chronology from 21 to -46 Years Before Present

Tree-ring width measurements from Switzerland provide a 68-year paleoclimate record ending 46 years after the 1950 baseline. The National Oceanic and Atmospheric Administration's National Centers for Environmental Information (NOAA NCEI) archives this data under its World Data Service for Paleoclimatology. The data was last updated in 1996.

Use Cases

• Reconstruct past temperature or precipitation anomalies by calibrating tree-ring width measurements against modern climate records.
• Analyze growth patterns and anomalies within the 68-year chronology to identify specific years of environmental stress.
• Cross-date this Swiss chronology with other European tree-ring series to build regional climate reconstructions.
• Use the calendar year before present (BP) timeline to align this proxy data with other paleoclimate records from the same period.

Strengths

• Data spans a specific 68-year period from 21 to -46 calendar years BP.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Provides a high-resolution annual proxy record for climate analysis.

Limitations

• Temporal coverage is limited to a short 68-year window, restricting analysis of long-term trends.
• The dataset is temporally stale, with its last update recorded in 1996.
• Geographic coverage is restricted to a single location in Switzerland, limiting regional conclusions.
