Meadow Mountain Tree Ring Chronology from British Columbia

Tree ring width measurements from the Meadow Mountain site in British Columbia, Canada, provide a paleoclimate record. The chronology spans 328 years, from 281 to -47 calendar years before present. This dataset is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology and was last updated in 1997.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width time-series.
• Calibrate the chronology against other regional proxy records using the calendar years before present (BP) index.
• Study long-term ecological trends in British Columbia forests using the site-specific growth parameters.

Strengths

• Chronology spans 328 calendar years, providing a multi-century climate record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at -47 BP, making the most recent data over 2000 years old and potentially less relevant for recent climate studies.
• Dataset metadata and specific measurement parameters are not detailed in the provided description, requiring further investigation.
