Northwest Territories Tree Ring Chronology for Paleoclimate Study

Tree ring width measurements from the Northwest Territories, Canada, used for climate reconstruction. The chronology spans 401 years, from 362 to -39 calendar years before present. Data is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1989.

Use Cases

• Reconstruct past temperature or precipitation anomalies from tree ring width chronologies.
• Calibrate climate models using a 401-year proxy record from the Northwest Territories.
• Analyze growth trends and potential climate stressors in trees over four centuries.
• Compare this tree ring series with other regional chronologies to identify broader climate patterns.

Strengths

• Chronology covers a 401-year time period for climate analysis.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last update date of 1989.
• Specific sample size, measurement parameters, and site details are not provided in the input.
