Tree Ring Chronology from Charlie Lake for Paleoclimate Reconstruction

NOAA/WDS Paleoclimatology archives tree ring width data from Charlie Lake in Canada's Northwest Territories. The chronology covers 220 years, from 182 to -38 calendar years before present. NOAA National Centers for Environmental Information (NCEI) published this study in 1988.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width time series.
• Calibrate climate models by comparing the 220-year ring width chronology with instrumental records.
• Analyze growth trends and extreme events within the dated tree ring sequence.
• Cross-date and validate other regional tree ring chronologies using this established series.

Strengths

• Covers a 220-year time period (182 to -38 BP).
• Part of the authoritative NOAA/NCEI Paleoclimatology archive.
• Provides a precisely dated chronology for a specific geographic site.

Limitations

• Data is temporally stale, last updated in 1988.
• Geographic coverage is limited to a single site in Northwest Territories.
• Unknown sample size and underlying measurement methodology.
