Tree ring width data from Ontario, Canada provides a 175-year chronology from 137 to -38 calendar years before present. The dataset is part of the NOAA NCEI World Data Service for Paleoclimatology, archived under the study type 'Tree Ring'. This specific collection was contributed by researcher Schweingruber and last updated in the NOAA system in 1988.
Use Cases
- Calibrating climate models by comparing tree ring width series with instrumental temperature records.
- Reconstructing past drought or growing season conditions in the Ontario region using annual ring width as a proxy.
- Analyzing the temporal response of tree growth (ring width) to documented historical climate events within the 175-year span.
- Cross-dating this site chronology (ITRDB CANA041) with other regional tree ring collections to validate climate signals.
Strengths
- Chronology covers a specific 175-year time period (137 to -38 BP).
- Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
- Includes precise geographic location information for the site in Ontario, Canada.
Limitations
- Temporal coverage is relatively short (175 years) compared to millennial-length tree ring chronologies.
- Data is from a single site (High Stone Lake), limiting spatial representativeness.
- The underlying data collection and NOAA archive update occurred in 1988, indicating potential staleness in metadata.
