Schweingruber Tree Ring Chronology from Webequie, Ontario

NOAA/WDS Paleoclimatology archives a tree-ring chronology from Webequie, Ontario, Canada. The data provides a 186-year record for paleoclimate reconstruction, covering the period from 148 to -38 calendar years before present (BP). This dataset was published by NOAA National Centers for Environmental Information in 1988.

Use Cases

• Reconstruct historical temperature or precipitation anomalies using annual tree-ring width measurements.
• Calibrate climate models by comparing the tree-ring chronology against known historical climate events.
• Analyze long-term ecological growth trends in boreal forests from the dated ring sequences.
• Establish regional dendrochronological reference chronologies for cross-dating other samples from Ontario.

Strengths

• Covers a 186-year time period (148 to -38 BP) for climate analysis.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data recency is limited, with a last update recorded in 1988.
• Specific sample size, measurement parameters, and data formats are not provided in the description.
• Geographic coverage is restricted to a single site in Ontario, Canada.
