NOAA/WDS Paleoclimatology archives a tree ring dataset for climate reconstruction in British Columbia, Canada. The chronology spans 696 years, from 647 to 49 calendar years before present. NOAA National Centers for Environmental Information (NCEI) published this study, last updated in 1999.
Use Cases
- Calibrate climate models using tree ring width as a proxy for temperature or precipitation over a 696-year period.
- Analyze growth anomaly patterns within the chronology to identify extreme climatic events like droughts.
- Compare this British Columbia tree ring series with other regional chronologies to study spatial climate teleconnections.
- Establish a dated environmental timeline for the region using the annual resolution of tree ring data.
Strengths
- 696-year temporal coverage from 647 to 49 BP provides a long baseline for analysis.
- Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.
Limitations
- Data is temporally stale, with a last recorded update in 1999.
- Specific sample size, measurement parameters, and site details are not provided in the summary.
