New Zealand Tree Ring Chronology from Logos Hill 2 Site

A tree-ring chronology from the Logos Hill 2 site in New Zealand, spanning 239 years from 210 to -29 calendar years before present (BP). The dataset is archived by the NOAA National Centers for Environmental Information under its Paleoclimatology program. This specific study was published or last updated in 1979.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology.
• Calibrate radiocarbon dates for the region using the dated tree-ring series.
• Analyze climate periodicity and extreme events from the 239-year tree-ring record.
• Compare this Southern Hemisphere tree-ring series with Northern Hemisphere paleoclimate proxies.

Strengths

• Time series covers 239 calendar years, providing a multi-century climate record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset is temporally stale, with a last updated date of 1979, potentially lacking modern reanalysis.
• The geographic scope is limited to a single site (Logos Hill 2) in New Zealand.
