NOAA's National Centers for Environmental Information provides a tree-ring chronology from the Craigieburn Valley, New Zealand. The dataset covers a 239-year period from 210 to -29 calendar years before present (BP). It was archived by NOAA NCEI's World Data Service for Paleoclimatology, with the record last updated in 1979.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology.
- Calibrate radiocarbon dates or other paleoclimate records by aligning the tree-ring time series.
- Analyze climate periodicity and extreme events over the 239-year span recorded in the tree-ring parameters.
Strengths
- Covers a 239-year time period (210 to -29 BP)
- Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology
Limitations
- Temporal coverage is relatively short for long-term climate trend analysis
- Data record was last updated in 1979, indicating potential staleness
- Geographic scope is limited to a single valley in New Zealand
