Ontario Tree-Ring Chronology for Paleoclimate Reconstruction

NOAA/WDS Paleoclimatology archives a tree-ring dataset from Ontario, Canada. The chronology covers 145 years, from 107 to -38 calendar years before present. NOAA National Centers for Environmental Information (NCEI) published this study in 1988.

Use Cases

• Reconstruct past climate variables like temperature using the tree-ring width chronology.
• Calibrate the chronology against known climate events using its calendar year BP time index.
• Analyze spatial climate patterns by linking the Ontario geographic location to other regional tree-ring records.
• Study ecological responses to historical climate shifts using the annual resolution tree-ring data.

Strengths

• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information (NCEI).
• Chronology provides a continuous 145-year time series for climate analysis.
• Explicit geographic location (Ontario, Canada) enables spatial studies.

Limitations

• Temporal coverage is limited to a specific 145-year period, which is short for some paleoclimate studies.
• Data is temporally stale, with a last documented update in 1988, potentially lacking modern reanalysis.
• Sample size and replication statistics for the tree-ring series are unknown from the provided metadata.
