Ontario Tree Ring Chronology from 116 to -38 BP

NOAA/WDS Paleoclimatology archives a tree ring dataset from Ontario, Canada. The data provides a chronology covering the period from 116 to -38 calendar years before present. This study is maintained by NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using tree ring width data.
• Calibrate radiocarbon dating models by aligning the tree ring chronology with known time periods.
• Analyze growth anomalies in the ring series to identify historical environmental events.
• Compare this Ontario chronology with other regional tree ring datasets for spatial climate analysis.

Strengths

• Chronology spans 154 years, from 116 to -38 BP.
• Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, with a last update recorded in 1988.
• Specific sample size, measurement parameters, and file details are not provided in the metadata.
