Tree ring width measurements from the Temagami Lake region in Ontario, Canada. The chronology covers 339 years, from 306 to 33 BC, providing a proxy for past climate conditions. Data is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1983.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing annual tree ring width variations.
- Calibrate and extend regional climate models using a high-resolution proxy record from 306 to 33 BC.
- Study forest response to historical climate events by examining growth patterns in the ring width time series.
- Cross-date and validate other tree ring chronologies from the boreal region of Canada using this established series.
