546 to -32 calendar years before present (BP) of tree-ring width data from the Gaspe Peninsula, Canada. This paleoclimatology dataset was archived by the NOAA National Centers for Environmental Information. The data was last updated in the NOAA system in 1982.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology.
- Calibrate climate models by comparing the tree-ring proxy record with instrumental data for the region.
- Analyze long-term forest growth trends and responses to environmental stressors from the ring-width series.
- Cross-date and validate other tree-ring chronologies from northeastern North America using this series.
Strengths
- Provides a 578-year continuous chronology from 546 to -32 BP.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- The dataset is temporally stale, with a last recorded update in 1982.
- Geographic coverage is limited to a single site (Ed's Gaspe) in Canada.
- Sample size and replication depth of the underlying tree cores are unknown.
