Canadian Tree Ring Chronology from 79 to 44 BC

Tree ring width measurements from a site in Saskatchewan, Canada, provide a climate proxy record spanning 123 years. The data is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. This specific chronology was last updated in the public record in 1994.

Use Cases

• Calibrating climate models by comparing tree ring width variations against known historical temperature and precipitation records.
• Reconstructing annual growing season conditions for central Canada during the late Holocene period.
• Analyzing the frequency of narrow rings, indicating drought or stress events, within this 123-year chronology.

Strengths

• Covers a specific 123-year time period from 79 to 44 BC.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's public record has not been updated since 1994, potentially missing newer methodological refinements.
• Limited to a single geographic site (Boreas SSA G4I3M Site 1), reducing regional representativeness.
