Tree-ring width measurements from New Zealand provide a proxy climate record spanning 443 years. The dataset covers the period from 399 to -44 calendar years before present. It is archived by the NOAA National Centers for Environmental Information as part of the PAGES Australasia 2k project.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree-ring width time-series as a climate proxy.
- Calibrate regional climate models by comparing the tree-ring chronology with instrumental records for the New Zealand location.
- Analyze the frequency of extreme climate events in the Australasian 2k context based on anomalies in the ring width series.
- Study long-term ecological growth trends in response to environmental changes using the annual resolution data.
Strengths
- Time series spans 443 calendar years, providing a multi-century climate record.
- Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Dataset is temporally stale, with a last update date recorded as 1994-01-01.
- Specific sample size, geographic coordinates, and measurement parameters are not detailed in the provided metadata.
