Tree ring width measurements from the Konini Forks site in New Zealand, used for paleoclimate reconstruction. The chronology covers a period from 238 to -26 calendar years before present. Data is archived by NOAA's National Centers for Environmental Information under its World Data Service for Paleoclimatology.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing tree ring width variations over time.
- Calibrate radiocarbon dating curves using the dated tree ring sequence as a reference.
- Study climate event impacts, such as volcanic eruptions, by identifying narrow ring years within the chronology.
- Compare this Southern Hemisphere tree ring series with Northern Hemisphere chronologies to analyze global climate patterns.
Strengths
- Chronology spans 264 years, from 238 to -26 BP.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Temporal coverage is relatively short for long-term climate trend analysis.
- Data is geographically limited to a single site in New Zealand.
- The last documented update was in 1976, indicating potential staleness.
