Tree ring width measurements from a site near Manapouri Dam, New Zealand, provide a 409-year chronology for paleoclimate reconstruction. The data is archived by NOAA's World Data Service for Paleoclimatology and originates from a study by Dunwiddie. The record coverage spans from 383 to -26 calendar years before present.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width time-series.
- Calibrate regional radiocarbon dating curves using the dated tree ring chronology.
- Compare this Southern Hemisphere tree ring record with Northern Hemisphere chronologies to study global climate teleconnections.
- Validate climate model simulations of the last few centuries using the proxy data from this site.
Strengths
- 409-year continuous chronology providing a multi-century climate record.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- The dataset is temporally stale, with a last documented update in 1976.
- The geographic coverage is limited to a single site in New Zealand, reducing regional representativeness.
- Specific sample depth, measurement statistics, and site details are not provided in the basic metadata.
