Tree ring width measurements from Mount Arrowsmith in Tasmania provide a 453-year climate proxy record ending 44 years before the Common Era. NOAA's National Centers for Environmental Information archived this paleoclimatology study for the World Data Service. The data was last updated in the repository in 1994.
Use Cases
- Reconstruct past temperature or precipitation anomalies in Tasmania using the tree ring width time-series.
- Calibrate regional climate models by comparing the 453-year tree ring chronology with instrumental records.
- Analyze growth response patterns to specific volcanic or climatic events within the recorded period.
- Cross-date and validate other paleoclimate archives from the Southern Hemisphere using this chronology.
Strengths
- Covers a 453-year continuous period from 409 to 44 BCE.
- Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends over 2000 years ago, limiting direct comparison to modern climate.
- Data is geographically limited to a single site (Mount Arrowsmith, Tasmania).
- The repository record has not been updated since 1994, potentially indicating stale metadata.
