NOAA/WDS Paleoclimatology archives a tree-ring dataset from Mt. Forster, British Columbia, Canada. The chronology covers 461 to -49 calendar years before present, providing proxy climate data. This dataset was published by NOAA National Centers for Environmental Information and was last updated in 1999.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a climate proxy.
- Calibrate and validate climate models by comparing simulated historical data with the tree-ring derived climate record.
- Analyze long-term climate trends and extreme events in British Columbia from the 510-year chronology.
- Perform cross-dating with other regional tree-ring chronologies using the annual resolution time series.
Strengths
- Chronology spans 510 calendar years (461 to -49 BP), offering a multi-century climate record.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends at 49 BP, limiting analysis of the most recent two millennia.
- Data is from a single geographic location (Mt. Forster), reducing regional representativeness.
- The dataset was last updated in 1999, indicating potential staleness in metadata or curation methods.
