New Zealand Tree Ring Chronology from 206 to -29 BP

Tree ring data from New Zealand provides a proxy climate record spanning 235 years, from 206 to -29 calendar years before present. The dataset is archived by NOAA's National Centers for Environmental Information under its Paleoclimatology program. The data was last updated in the NOAA system in 1979.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width time-series.
• Calibrate radiocarbon dating curves for the New Zealand region by cross-referencing the dated tree ring sequence.
• Analyze the frequency of extreme climate events indicated by patterns in the annual ring growth data.

Strengths

• Covers a 235-year time period from 206 to -29 BP.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last known update was in 1979, indicating it is a static archival record.
• Specific sample size, measurement parameters, and site details are not provided in the basic metadata.
