Tree Ring Chronology from Lac Onatchiway, Quebec (109 to -43 BP)

NOAA's World Data Service for Paleoclimatology archives this tree ring chronology dataset from Lac Onatchiway, Quebec, Canada. The data provides parameters for dendrochronological analysis covering a time period from 109 to -43 calendar years before present (BP). It was published by NOAA NCEI, with the last recorded update in 1993.

Use Cases

• Reconstructing past temperature or precipitation anomalies using tree ring width or density parameters.
• Calibrating and validating climate models for the Holocene period using the 152-year chronology.
• Analyzing climate extremes or events in Quebec, Canada, circa 109 to -43 BP from the archived parameters.

Strengths

• Data spans a 152-year chronology (109 to -43 BP), providing a specific historical window.
• Archived by the authoritative NOAA World Data Service for Paleoclimatology, ensuring formal curation.

Limitations

• Temporal coverage is relatively short (152 years) compared to other paleoclimate records.
• Data is geographically limited to a single site (Lac Onatchiway, Quebec).
• The dataset has not been updated since 1993, potentially lacking modern reanalysis.
