Tree Ring Chronology from St. George, Manitoba, 123 BP Span

123 calendar years of tree ring data, from 75 to -48 years before present, provide a proxy record for past climate conditions in Manitoba, Canada. The dataset is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. This study was published in 1998.

Use Cases

• Calibrating tree-ring width or density parameters against instrumental climate records to reconstruct past temperatures.
• Analyzing the time-series of tree-ring parameters to identify periods of climatic stress or anomalous growth years.
• Comparing this chronology from Manitoba with other ITRDB series to study spatial patterns of past climate events.

Strengths

• Covers a 123-year time period (75 to -48 BP) for climate analysis.
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) and NOAA WDS Paleoclimatology network.

Limitations

• Temporal coverage is relatively short (123 years) for long-term climate trend analysis.
• Data is geographically limited to a single site (St. George, Manitoba).
• The dataset has not been updated since its publication in 1998.
