NOAA/WDS Paleoclimatology archives a tree ring chronology from Takahe Valley, New Zealand. The dataset covers a time period from 320 to -29 calendar years before present (BP). It is maintained by the NOAA National Centers for Environmental Information.
Use Cases
- Reconstruct past temperature or precipitation using the tree-ring width chronology.
- Calibrate radiocarbon dates or other climate proxies using the dated tree-ring series.
- Analyze climate extremes or trends within the 349-year period covered by the chronology.
Strengths
- Data spans 349 years (320 to -29 BP), providing a multi-century climate record.
- Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends at -29 BP (approximately 1979 CE), with no updates since the 1979 publication.
