Cassiar Mountain Tree Ring Chronology for Paleoclimate Reconstruction

166-year tree ring chronology from the Cassiar region of British Columbia, Canada, spanning from 133 to -33 calendar years before present. This paleoclimatology dataset was archived by NOAA's National Centers for Environmental Information under its World Data Service. The data collection was last updated in 1983.

Use Cases

• Calibrating climate models by correlating annual tree ring width measurements with historical temperature and precipitation records.
• Reconstructing past drought events by analyzing patterns of narrow rings within the chronology.
• Studying ecological responses to climate forcing by examining growth suppression and release events in the ring series.

Strengths

• Chronology covers a 166-year time period (133 to -33 BP).
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, with a last update date of 1983.
• The specific sample size (number of tree cores) and replication statistics are unknown.
