Canadian Tree-Ring Chronology for Paleoclimate Analysis

NOAA/WDS Paleoclimatology archives a tree-ring chronology from Manitoba, Canada. The data provides a temporal record spanning 176 years, from 127 to -49 calendar years before present. It was published by the NOAA National Centers for Environmental Information in 1999.

Use Cases

• Reconstruct historical temperature or precipitation anomalies by analyzing the tree-ring width chronology.
• Calibrate climate models using the dated proxy record covering 176 years before present.
• Study regional climate extremes in Manitoba by examining year-to-year variations in the ring-width series.
• Cross-date other tree-ring records from North America using this established chronology as a reference.

Strengths

• Temporal coverage spans 176 specific calendar years (127 to -49 BP).
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.
• Focuses on a single geographic location (Manitoba, Canada) for clear spatial context.

Limitations

• Dataset is temporally stale, with a last update recorded in 1999.
• The specific parameters (e.g., ring width, density measurements) and sample depth are not detailed in the provided description.
• Geographic scope is limited to a single site in Manitoba.
