Willow Lake Tree Ring Chronology from Northwest Territories

Tree ring width data from Willow Lake in Canada's Northwest Territories provides a 138-year climate proxy record. The chronology spans from 100 to -38 calendar years before present, indicating it extends into the future relative to the 1950 baseline. This archived study is maintained by NOAA's National Centers for Environmental Information under its World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree_ring_width time series.
• Calibrate climate proxy models using the 138-year chronology from 100 to -38 BP.
• Study subarctic forest growth responses to climate events within the Northwest Territories geographic location.
• Compare this ITRDB CANA044 site chronology with other regional tree-ring datasets for spatial climate analysis.

Strengths

• 138-year continuous chronology from 100 to -38 calendar years BP.
• Data archived and standardized by NOAA's authoritative World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is relatively short for long-term climate trend analysis.
• Geographic scope is limited to a single site (Willow Lake) in Northwest Territories.
• Data is temporally stale, last updated in 1988.
