Canadian Tree Ring Chronology from 890 to -42 BP

NOAA/WDS Paleoclimatology archives a tree ring chronology from the Campbell Dolomite Upland in Canada's Northwest Territories. The data covers a period from 890 to -42 calendar years before present. This record was published by NOAA National Centers for Environmental Information in 1992.

Use Cases

• Calibrating climate models by comparing tree ring width variations against known historical climate proxies.
• Reconstructing past temperature or precipitation anomalies for the Northwest Territories region using the annual resolution chronology.
• Analyzing long-term ecological stress events from the tree ring record spanning over 900 years.
• Establishing a dated chronology for cross-referencing with other paleoclimate archives from the same geographic location.

Strengths

• Chronology spans over 930 calendar years, from 890 to -42 BP.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.

Limitations

• Dataset is temporally stale, with a last recorded update in 1992.
• Specific sample size, measurement parameters, and replication statistics are not provided in the input.
