New Zealand Tree Ring Chronology from Ghost Creek

Tree ring data from the Ghost Creek site in New Zealand provides a climate proxy record spanning 185 years, from 155 to -30 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information's World Data Service for Paleoclimatology. This paleoclimatology study was published in 1980.

Use Cases

• Reconstruct past temperature or precipitation variations using the tree-ring width chronology.
• Calibrate the tree-ring chronology against known climate events within the 185-year time period.
• Analyze growth patterns in the tree-ring series to identify periods of environmental stress.

Strengths

• 185-year time-series coverage provides a multi-century climate proxy.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to 185 years, which is relatively short for long-term climate trend analysis.
• The dataset's last update was in 1980, indicating it is a static historical archive with no recent additions.
