Tree ring width measurements from Manitoba, Canada, covering a 298-year period from 260 to -38 calendar years before present. The dataset is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1988.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree ring width time-series.
- Calibrate climate models by comparing the chronology with other proxy records from the same period.
- Analyze growth trends and extreme events (e.g., volcanic cooling) within the 298-year record.
- Study the response of boreal tree species to climate forcing over centennial timescales.
Strengths
- Time-series covers a 298-year period, providing a multi-century climate proxy.
- Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, with a last update date of 1988.
- The geographic coverage is limited to a single site in Manitoba, Canada.
- The exact sample size (number of tree cores) and measurement methodology are not specified in the provided description.
