New Zealand Tree Ring Chronology from Hauhungatahi Site C

781 annual tree ring measurements from the Hauhungatahi Site C near Tongariro, New Zealand, spanning from 738 to -43 calendar years before present. This paleoclimatology dataset was archived by NOAA National Centers for Environmental Information (NCEI) under the World Data Service for Paleoclimatology. The data was last updated in 1993.

Use Cases

• Reconstruct past temperature or precipitation anomalies from the annual tree ring width parameter.
• Calibrate climate models by comparing the tree ring chronology time series against instrumental records.
• Analyze the frequency of extreme climate events in the Tongariro region over the 781-year period.
• Study ecological responses to volcanic activity using the tree ring record from the Tongariro volcanic area.

Strengths

• 781-year continuous annual chronology providing a long-term climate proxy.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Specific geographic location (Hauhungatahi Site C, Tongariro, New Zealand) enables localized analysis.

Limitations

• Temporal coverage ends at -43 BP (43 BCE), with no overlap with recent instrumental periods.
• Data is from a single site, limiting spatial representativeness for broader New Zealand climate.
• The dataset was last updated in 1993 and may not reflect more recent methodological standards.
