Tree Ring Chronology from Arrowsmith Mountain in British Columbia

354 calendar years of tree ring data, spanning from 321 to -33 years before present, provide a paleoclimate record. This dataset contains parameters from tree rings located in British Columbia, Canada, archived by NOAA's National Centers for Environmental Information. The data was published in 1983.

Use Cases

• Analyze tree ring width parameters to reconstruct past temperature or precipitation variability.
• Correlate the tree ring chronology with other paleoclimate proxies for regional climate model validation.
• Study the growth patterns of Tsuga mertensiana (TSME) trees over a 354-year period.
• Use the calendar years before present (BP) timeline for dating environmental events.

Strengths

• Data covers a 354-year time period (321 to -33 BP).
• Specific geographic location (British Columbia, Canada) and tree species (TSME) are documented.

Limitations

• The dataset's last update was in 1983, indicating potentially stale metadata or methods.
• Unknown row count and sample size limit statistical analysis confidence.
• Data coverage ends at -33 BP, which may not connect directly to modern instrumental records.
