67 to -47 calendar years before present (BP) of tree ring data from Manitoba, Canada. This paleoclimatology study is archived by the NOAA National Centers for Environmental Information under the World Data Service. The data was published in 1997.

Use Cases

• Reconstruct past temperature or precipitation using tree ring width parameters.
• Calibrate climate models with proxy data from the 114-year chronology.
• Analyze growth patterns in the St. George - St. Jean Baptiste site for ecological studies.
• Compare this ITRDB CANA189 series with other regional tree ring chronologies.

Strengths

• Data covers a 114-year time period (67 to -47 BP).
• Archived and maintained by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is relatively short for long-term climate trend analysis.
• Data is geographically limited to a single site in Manitoba, Canada.
• The dataset is temporally stale, with a last update recorded in 1997.
