Tree ring width data from a Putara, New Zealand site provides a 347-year climate record ending 43 years before the present era. The NOAA National Centers for Environmental Information archived this paleoclimatology study for the World Data Service. The data was last updated in the repository in 1993.
Use Cases
- Reconstruct past temperature or precipitation anomalies from annual tree ring width measurements.
- Calibrate radiocarbon dating or other chronological models using the dated tree ring sequence.
- Analyze climate response functions by correlating ring width series with instrumental climate records.
- Compare this New Zealand chronology with other Southern Hemisphere tree ring datasets for hemispheric climate patterns.
Strengths
- 347-year continuous chronology from 304 to 43 BCE.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- The dataset covers a single geographic location (Putara, New Zealand), limiting spatial representativeness.
- The data record ends over 2000 years ago, with no overlap with modern instrumental periods.
- Repository metadata indicates the data was last updated in 1993, suggesting potential staleness in documentation or access methods.
