Canadian Northwest Territories Tree Ring Chronology 97 to -38 BP

Tree ring width measurements from Northwest Territories, Canada, covering 135 calendar years from 97 to -38 years before present. The dataset is archived by NOAA's National Centers for Environmental Information under its Paleoclimatology World Data Service. The data was published in 1988.

Use Cases

• Reconstruct past temperature or precipitation anomalies using tree ring width as a climate proxy for the years 97 to -38 BP.
• Calibrate and validate other paleoclimate records by comparing the tree ring chronology with other regional datasets.
• Analyze growth patterns and extreme events within the 135-year time series to identify climatic stressors.
• Study the response of boreal forest tree species to climate conditions in the Northwest Territories region.

Strengths

• Time series covers 135 calendar years (97 to -38 BP) providing a discrete historical snapshot.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.

Limitations

• Dataset is temporally stale, with a last update date of 1988, potentially lacking modern methodological refinements.
• Geographic coverage is limited to a single location in the Northwest Territories, Canada.
• The specific sample size (number of tree cores or sites) is unknown, limiting assessment of statistical robustness.
