Quebec Tree Ring Chronology from 300 to -24 BP

324 calendar years of tree ring data from Fort Chimo, Quebec, Canada, covering the period from 300 to -24 years before present. The dataset was archived by NOAA's World Data Service for Paleoclimatology and is associated with a study by Fritts. This paleoclimatology record was last updated in 1974.

Use Cases

• Calibrating climate models by comparing reconstructed temperature or precipitation proxies from tree ring width against instrumental records.
• Analyzing long-term climate trends and anomalies in subarctic Quebec using the annual resolution of the ring chronology.
• Cross-dating archaeological wood samples from the region by matching ring patterns to this established master chronology.
• Investigating the response of boreal tree growth to climatic forcing events within the 324-year time span.

Strengths

• 324-year temporal coverage provides a multi-century climate record.
• Data is curated and archived by the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1974, making methodologies and metadata potentially outdated.
• Geographic coverage is limited to a single site (Fort Chimo, Quebec), limiting regional representativeness.
• Specific measured parameters (e.g., ring width, density) and sample depth are unknown from the provided description.
