Lac Natuak Tree Ring Chronology for Paleoclimate Reconstruction

98 to -38 calendar years before present (BP) of tree ring data from Quebec, Canada, archived by the NOAA National Centers for Environmental Information (NCEI). The dataset is part of the World Data Service for Paleoclimatology and was last updated in 1988.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
• Calibrate climate models by comparing the ring width series to known historical climate periods.
• Analyze growth trends and potential environmental stressors from the annual ring measurements.
• Cross-date this chronology with other regional tree ring series to validate temporal coverage.

Strengths

• Covers a 136-year time period from 98 to -38 BP.
• Authoritatively sourced from NOAA NCEI's World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is relatively short for long-term climate trend analysis.
• Data is geographically limited to a single site (Lac Natuak, Quebec).
• Last update was in 1988, indicating potential staleness in metadata or access methods.
