Mt. Mcintyre Tree Ring Chronology for Yukon Climate Reconstruction

348 calendar years of tree-ring data, from 299 to -49 years before present, provide parameters for climate reconstruction. The dataset is part of the NOAA/WDS Paleoclimatology archive, contributed by the NOAA National Centers for Environmental Information. It was archived in 1999.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a climate proxy.
• Calibrate climate models by comparing the tree-ring time-series data against instrumental records for the Yukon region.
• Analyze long-term climate trends and variability over a 348-year period in the high-latitude boreal forest.
• Study ecological responses to past climate events by examining growth patterns in the Mt. Mcintyre tree-ring record.

Strengths

• Covers a 348-year time period (299 to -49 BP), providing a multi-century climate record.
• Sourced from the authoritative NOAA National Centers for Environmental Information Paleoclimatology archive.
• Includes specific geolocation data for the Yukon Territory, Canada.

Limitations

• Temporal coverage ends at -49 BP (approximately 49 BCE), with no data for more recent millennia.
• Sample size, tree species, and replication depth are unknown from the provided metadata.
• Data was last updated in 1999, potentially lacking modern reanalysis or updated calibration.
