Kathleen Lake Tree Ring Chronology from Yukon Territory

NOAA's World Data Service for Paleoclimatology archives this tree ring dataset from Kathleen Lake in Yukon Territory, Canada. The data provides a chronology covering 227 years, from 194 to -33 calendar years before present (BP). It was published by NOAA National Centers for Environmental Information in 1983.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree-ring width series.
• Calibrate climate proxy models using the dated annual chronology from this specific site.
• Study the response of boreal forest tree growth to historical climate events recorded in the ring measurements.
• Compare this Yukon Territory chronology with other regional tree-ring datasets to identify broader climate patterns.

Strengths

• Chronology spans 227 years (194 to -33 BP), providing a multi-century climate record.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, last updated in 1983, and may lack modern reanalysis.
• The specific sample size (number of tree cores), measurement parameters, and data formats are unknown.
