Tree ring width measurements from Tasmania, Australia, provide a paleoclimate record. The chronology spans 665 years, from 640 to -25 calendar years before present. The dataset was archived by NOAA's World Data Service for Paleoclimatology and last updated in 1975.
Use Cases
- Calibrating climate models by comparing reconstructed temperature or precipitation inferred from tree ring width series against instrumental records.
- Analyzing growth anomaly patterns in the ring width chronology to identify past climatic extremes like droughts or cold periods in Tasmania.
- Establishing a dated tree ring chronology (ITRDB AUSL018) for cross-dating other sub-fossil wood samples from the region.
Strengths
- Chronology covers a 665-year period from 640 to -25 BP.
- Data is curated and archived by the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- The dataset's last update was in 1975, potentially missing modern methodological refinements or additional samples.
- Specific sample depth, replication statistics, and measurement parameters are not detailed in the provided description.
