Swiss Tree Ring Chronology from La Sagne for Paleoclimate Analysis

87 to -42 calendar years before present of tree ring data from Switzerland, compiled by the NOAA National Centers for Environmental Information. This paleoclimatology study provides a chronology for reconstructing past environmental conditions. The data was archived in the NOAA/WDS Paleoclimatology collection and last updated in 1992.

Use Cases

• Calibrating climate models by comparing the tree ring width chronology with known historical climate periods.
• Reconstructing past temperature or precipitation anomalies in Western Europe using the dated tree ring series.
• Analyzing growth patterns in the chronology to identify environmental stressors or extreme events during the covered time span.
• Cross-dating other regional tree ring records using the established La Sagne chronology as a reference.

Strengths

• Temporal coverage spans 129 years (87 to -42 BP), providing a multi-century environmental record.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• The dataset's last update was in 1992, indicating potential staleness and lack of recent methodological revisions.
• Specific sample size, measurement parameters, and replication statistics are unknown from the provided description.
