Tree ring width measurements from Tsuga mertensiana (TSME) trees at Mount Cheam in British Columbia, Canada. The chronology spans 341 years, from 292 to -49 calendar years before present, archived by NOAA NCEI's World Data Service for Paleoclimatology. The data was published in 1999.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing the annual tree ring width series.
- Calibrate the tree ring chronology against known climate events within the 341-year period.
- Study the growth response of Tsuga mertensiana (TSME) to environmental stressors over multiple centuries.
- Compare this site-specific chronology with other regional tree ring datasets to identify broader climate patterns.
Strengths
- Chronology covers a continuous 341-year period, providing a multi-century climate record.
- Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
- Specifics on tree species (Tsuga mertensiana) and geographic location (Mount Cheam, BC) are documented.
Limitations
- Temporal coverage ends at -49 BP (approximately 1999 CE), with no updates since its 1999 publication.
- The dataset is from a single geographic site, limiting spatial representativeness.
- Raw measurement data and sample depth metadata are not detailed in the provided description.
