New Zealand Tree Ring Chronology from 286 to -26 BP

NOAA/WDS Paleoclimatology archives a tree ring dataset from the Waiomu site in New Zealand. The data provides a chronology covering 312 years, from 286 to -26 calendar years before present. It was published by NOAA National Centers for Environmental Information in 1976.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
• Calibrate climate models by comparing the tree ring proxy record with instrumental data for the region.
• Analyze the frequency of climatic events like droughts by examining the variance in the ring width series.
• Study ecological responses to climate change by correlating the growth chronology with known historical events.

Strengths

• Chronology spans a defined 312-year period from 286 to -26 BP.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, with a last update recorded in 1976.
• The specific sample size, measurement parameters, and replication depth are unknown from the provided metadata.
• Geographic coverage is limited to a single site (Waiomu) in New Zealand.
