New Zealand Tree Ring Chronology from 743 to 78 BP

Tree ring data from New Zealand spans 665 years, from 743 to 78 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information under its Paleoclimatology program. The record was last updated in 1872.

Use Cases

• Reconstruct annual climate variables like temperature or precipitation using tree-ring width measurements.
• Calibrate radiocarbon dating or other chronological methods against the 665-year tree-ring chronology.
• Analyze climate event frequency, such as droughts or volcanic eruptions, indicated by growth anomalies in the ring records.
• Model past atmospheric circulation patterns in the South Pacific by comparing this chronology with others from the region.

Strengths

• Time coverage spans 665 calendar years (743 to 78 BP).
• Data originates from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last update date is 1872, indicating it is a historical archive with no recent revisions.
• Specific parameters, sample size, and measurement details are unknown without accessing metadata.
