Dividing Lake Tree Ring Chronology from Ontario, Canada

NOAA/WDS Paleoclimatology archives a tree-ring chronology dataset from Dividing Lake, Ontario. The data covers a time period from 288 to -44 calendar years before present. It was contributed by Guyette and last updated in 1994.

Use Cases

• Reconstruct past temperature or precipitation anomalies using annual tree-ring width measurements.
• Calibrate climate models by comparing the chronology against known historical climate events.
• Analyze growth trends and extreme events (e.g., droughts) encoded in the ring width time series.

Strengths

• Data spans 332 years of historical coverage (288 to -44 BP).
• Sourced from the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Temporal coverage ends 44 years before present, lacking recent decades.
• Dataset was last updated in 1994, indicating potential staleness in metadata or access methods.
• Specific sample size, geographic precision, and measurement parameters are unknown from the description.
