212 calendar years of tree ring width data from 166 to -46 years before present, used for climate reconstruction. The dataset is archived by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. This paleoclimatology study was last updated in 1996.
Use Cases
- Reconstruct past temperature or precipitation variations using the tree ring width time-series.
- Calibrate climate models by comparing the tree ring chronology with instrumental climate records.
- Analyze growth trends and extreme climate events captured in the ring width parameter.
- Study the response of Tsuga mertensiana (TSME) to historical climate conditions at the Mount Porter site.
Strengths
- Covers a 212-year time period for climate analysis.
- Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
- Provides a specific geographic location in British Columbia, Canada.
Limitations
- The dataset is temporally stale, last updated in 1996.
- The raw sample size and replication depth of the tree ring chronology are unknown.
- Coverage ends 46 years before present, limiting analysis of the most recent climate period.
