Quebec Tree Ring Chronology From 111 to -44 BP

Tree ring data from Lac Liberal in Quebec, Canada, provides a paleoclimate record spanning 155 years. The chronology covers the period from 111 to -44 calendar years before present, calibrated for calendar year dating. This archived study is maintained by NOAA's National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology.
• Calibrate climate proxy models for the Quebec region using the dated time-series.
• Analyze inter-annual to decadal climate variability in eastern Canada during the 155-year period.
• Validate other paleoclimate proxies for the 1st century BC to 1st century AD timeframe using this ITRDB series.

Strengths

• Data spans a specific 155-year period from 111 to -44 BP.
• Archived within the authoritative International Tree-Ring Data Bank (ITRDB) under NOAA/NCEI.

Limitations

• Very small temporal coverage of only 155 years limits long-term trend analysis.
• Single geographic location (Lac Liberal, Quebec) limits spatial representativeness.
• Data last updated in 1994, potentially lacking modern re-calibration or metadata enhancements.
