Little Barrier Island Tree Ring Chronology From 160 to 31 BCE

NOAA's Paleoclimatology archive provides a tree ring chronology from Little Barrier Island, New Zealand. The dataset covers a 191-year period from 160 to 31 calendar years before present (BCE). This study was archived by NOAA National Centers for Environmental Information in 1981.

Use Cases

• Calibrating climate models using the tree ring width time-series as a proxy for past temperature or precipitation.
• Analyzing growth anomaly patterns in the chronology to identify volcanic or climatic events affecting the region.
• Cross-dating this chronology with other Southern Hemisphere tree ring series to validate regional climate signals.

Strengths

• Time-series covers 191 consecutive years from 160 to 31 BCE.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Dataset is small, containing a single chronology time-series for one site.
• Data is temporally stale, last updated in 1981, potentially lacking modern reanalysis.
