Mount Becher Tree Ring Chronology from British Columbia

Tree ring data from Mount Becher in British Columbia, Canada, covering a period from 282 to -47 calendar years before present. The dataset is archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology. This study was published in 1997.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree-ring width chronology.
• Calibrate the tree-ring chronology against other proxy records for the specified time period from 282 to -47 BP.
• Analyze growth patterns in Tsuga mertensiana (TSME) trees from the ITRDB CANA470 site for ecological studies.

Strengths

• Data spans 329 years of calendar years before present.
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection.

Limitations

• Temporal coverage ends at -47 BP, providing no data for recent centuries.
• Data is from a single geographic site (Mount Becher), limiting regional representativeness.
• Last metadata update was in 1997, indicating potential staleness in documentation.
