Swiss Tree Ring Chronology From 140 to 46 BCE

Tree ring width measurements from Vordemwald, Switzerland, providing a paleoclimate record. The chronology covers a period from 140 to 46 calendar years before present (BCE). Data is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1996.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree ring width time-series.
• Calibrate and validate other paleoclimate proxy records from the Alpine region using this chronology.
• Analyze growth patterns and extreme events in the tree ring series to identify historical droughts or cold periods.

Strengths

• Time series spans 94 years (140 to 46 BCE), providing a multi-decadal climate record.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last recorded update in 1996.
• Geographic coverage is limited to a single site (Vordemwald) in Switzerland.
• The specific parameters and measurement methods are not detailed without consulting metadata.
