New Zealand tree-ring width data from the Moa Park site, spanning 327 to -41 calendar years before present, provides a paleoclimate record for the Australasia region. The dataset is archived by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. It was last updated in the repository in 1991.
Use Cases
- Reconstruct past temperature or precipitation in New Zealand by analyzing the annual tree-ring width time series.
- Calibrate climate models for the Australasia region using the multi-century tree-ring width chronology.
- Study extreme climate events in the pre-instrumental era by identifying narrow or wide ring anomalies in the series.
- Compare the Moa Park tree-ring width record with other proxy datasets to assess regional climate coherence.
Strengths
- Time series covers a period of 368 years (327 to -41 BP).
- Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Data recency is low, with a last repository update in 1991, potentially missing newer methodological refinements.
- Geographic scope is limited to a single site (Moa Park, New Zealand), limiting spatial analysis.
