Lac Chevrillon Tree Ring Chronology For Climate Reconstruction

NOAA NCEI archives this paleoclimatology dataset containing tree ring parameters from Lac Chevrillon in Quebec, Canada. The data provides a time series covering 191 calendar years, from 153 to -38 years before present. The National Centers for Environmental Information (NCEI) under the World Data Service for Paleoclimatology compiled and published this study.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
• Calibrate climate models by comparing the proxy tree ring data with instrumental records for the region.
• Analyze growth patterns and extreme events captured in the ring series for ecological studies.
• Establish a dated chronology for the Lac Chevrillon site to serve as a reference for other regional studies.

Strengths

• Data covers a specific 191-year time period (153 to -38 BP).
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to 191 years, which is a relatively short period for some paleoclimate analyses.
• The dataset was last updated in 1988, indicating potential staleness and lack of recent methodological revisions.
• Geographic scope is restricted to a single site (Lac Chevrillon), limiting broad spatial inferences.
