Swiss Alpine Tree Ring Chronology from 137 to -46 BP

Swiss Alpine tree ring data from the Alpiglen site provides a chronology for paleoclimate reconstruction. The dataset covers 183 years, from 137 to -46 calendar years before present. NOAA National Centers for Environmental Information archived this tree ring study in 1996.

Use Cases

• Reconstruct past temperature or precipitation anomalies using annual tree ring width measurements.
• Calibrate climate models by comparing the tree ring chronology with instrumental records for the region.
• Analyze growth patterns in Picea abies (spruce) trees to infer ecological responses to historical events.
• Establish a dated master chronology for cross-referencing with other paleoclimate archives in Western Europe.

Strengths

• Chronology spans 183 years, from 137 to -46 calendar years BP.
• Data is archived and curated by NOAA's World Data Service for Paleoclimatology, an authoritative source.

Limitations

• Data is temporally stale, with a last recorded update in 1996.
• The specific sample size, measurement parameters, and raw ring width data are not provided in the description.
• Geographic coverage is limited to a single site (Alpiglen) in Switzerland.
