Canadian Tree Ring Chronology from 84 to -49 BP

Tree ring data from the St. George - Fort Dufferin site in Manitoba, Canada, used for paleoclimate reconstruction. The chronology covers the period from 84 to -49 calendar years before present. This archived study is provided by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width chronology.
• Calibrate climate models using the high-resolution proxy data from the specified time period.
• Study regional climate events in Manitoba, Canada, by examining variations in the ring width parameter.
• Perform cross-dating with other regional tree ring chronologies to validate climate signals.

Strengths

• Data spans 133 years (from 84 to -49 BP), providing a multi-decadal climate record.
• Archived and maintained by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is relatively short (133 years) compared to other paleoclimate proxy records.
• Data is geographically limited to a single site in Manitoba, Canada.
• The dataset was last updated in 1999, indicating potential staleness in metadata or availability.
