New Zealand Tree Ring Chronology from 117 to -28 BP

Tree ring data from New Zealand provides a proxy climate record covering 145 years, from 117 to -28 calendar years before present. This paleoclimatology study is archived and maintained by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. The data was last updated in the NOAA system in 1978.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a proxy.
• Calibrate radiocarbon dating or other dating methods by aligning the tree-ring series with known calendar years.
• Analyze the frequency of extreme climate events in the New Zealand region during the covered time period from the ring patterns.
• Compare this Southern Hemisphere tree-ring record with Northern Hemisphere chronologies to study global climate teleconnections.

Strengths

• Time series covers 145 specific calendar years (117 to -28 BP), providing a focused historical snapshot.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last known update was in 1978, potentially missing modern re-analysis or corrections.
• The geographic coverage is limited to a single site in New Zealand, limiting regional generalizations.
• Specific parameters like ring width measurements or climate correlations are not detailed in the provided metadata.
