Southern Manitoba Tree Ring Chronology from 664 to -49 BP

A tree ring chronology from the St. George region of Southern Manitoba, Canada, covering 713 years from 664 to -49 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. It was last updated in the NOAA system in 1999.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width series.
• Calibrate climate models using the precisely dated annual resolution of the ring width data.
• Study regional climate extremes and their frequency by identifying marker years in the ring record.
• Compare this chronology with other regional series to analyze spatial climate patterns over centuries.

Strengths

• Covers a 713-year period from 664 to -49 BP, providing a multi-century climate record.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last known update was in 1999, indicating potential staleness in metadata or availability.
• Specific sample depth, replication statistics, and measurement details are not provided in the basic description.
