St. George Parker Farm Tree Ring Chronology from Manitoba

73 to -48 calendar years before present (BP) of tree ring parameters from Manitoba, Canada. This paleoclimatology study is archived by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. The data was last updated in the NOAA system in 1998.

Use Cases

• Calibrate climate models by comparing tree ring width data to known historical climate proxies.
• Analyze growth anomaly patterns in the ring width time-series to identify past drought or favorable growing periods.
• Establish a dated chronology for the region by cross-referencing this series with other ITRDB (International Tree-Ring Data Bank) records.

Strengths

• Covers a 121-year time period (73 to -48 BP), providing a snapshot of pre-industrial conditions.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology and ITRDB.

Limitations

• Temporal coverage is limited to a specific 121-year window, not a long continuous record.
• Data is geographically specific to a single site (Manitoba, Canada), limiting broad spatial analysis.
• The dataset metadata and underlying data were last updated in 1998, indicating potential staleness.
