Tree ring width chronology data from Loch Maree in the British Isles, covering 222 years from 194 to -28 calendar years before present. The dataset is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1978. It was contributed by researcher Schweingruber as part of the International Tree-Ring Data Bank.
Use Cases
- Calibrate climate models by correlating tree ring width variations with known temperature and precipitation records for the region.
- Reconstruct annual climate conditions for the British Isles over a 222-year historical period using the tree ring proxy.
- Analyze growth anomaly years within the chronology to identify extreme historical climate events like droughts or cold periods.
- Compare the Loch Maree pine chronology with other ITRDB series to assess spatial climate patterns across the United Kingdom.
Strengths
- 222-year continuous chronology providing multi-century climate context.
- Data is part of the authoritative International Tree-Ring Data Bank (ITRDB) collection, ensuring standardized formatting.
Limitations
- Sample size and replication depth are unknown, limiting statistical confidence in year-to-year values.
- Temporal coverage ends at -28 BP, providing no data for the most recent two millennia.
- Data was last updated in 1978, and newer collections or methodological improvements may not be reflected.
