Lac Duparquet Tree Ring Width Chronology from 750 to -37 BP

Tree-ring width measurements from the Lac Duparquet site in Quebec, Canada. The chronology covers 787 years, from 750 to -37 calendar years before present. Data is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1987.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width proxy.
• Calibrate the chronology against other regional climate records using its 787-year time span.
• Analyze growth trends and extreme events within the time-series data for the Quebec region.

Strengths

• 787-year continuous chronology from 750 to -37 BP.
• Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.
