Swiss Tree Ring Chronology from Les Arbepins 110 to -29 BP

NOAA/WDS Paleoclimatology archives a tree ring chronology from the Les Arbepins site in Switzerland. The dataset provides annual growth measurements for the PISY (Pinus sylvestris) species, covering the period from 110 to -29 calendar years before present. This study was contributed by Schweingruber and is managed by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the annual tree ring width series.
• Calibrate radiocarbon dating or validate other paleoclimate proxies by cross-dating the PISY ring chronology.
• Analyze growth response to environmental stressors by examining the ring width parameter over the 139-year span.
• Study regional climate patterns in Western Europe by integrating this site chronology with other ITRDB series.

Strengths

• Data spans 139 years (110 to -29 BP), providing a multi-decadal climate record.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology with associated metadata.

Limitations

• Temporal coverage is relatively short (139 years) compared to millennial-length tree ring chronologies.
• Data is geographically limited to a single site (Les Arbepins, Switzerland), reducing regional representativeness.
• The dataset was last updated in 1979, indicating it is a static archive with no recent revisions.
