Tree Ring Chronology from Manitoba, Canada (128 to -44 BP)

NOAA NCEI archives a tree-ring chronology dataset from the St. George, Winnipeg, QUMA, and ITRDB CANA192 sites in Manitoba, Canada. The data covers the period from 128 to -44 calendar years before present, representing over 170 years of proxy climate information. This study was published by the NOAA National Centers for Environmental Information in 1994.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree-ring width chronology.
• Calibrate climate models for the Canadian Prairies region using the dated proxy record spanning 128 to -44 BP.
• Perform cross-dating with other regional tree-ring series using the standardized chronology data.
• Study the frequency of climatic extremes or disturbances recorded in the ring-width parameter for Manitoba.

Strengths

• Data spans over 170 years of proxy climate record (128 to -44 BP).
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at -44 BP (approximately 44 BCE), lacking recent centuries.
• Data is from a specific geographic region (Manitoba, Canada), limiting broader spatial analysis.
• Last metadata update was in 1994, indicating potential staleness in documentation.
