New Zealand Tree Ring Chronology from 220 to 29 BC

Tree ring data from New Zealand covers a 250-year period from 220 to 29 calendar years before present. The dataset is part of the NOAA/WDS Paleoclimatology archive and was published by NOAA National Centers for Environmental Information. It was last updated in the NOAA system in 1979.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree-ring width chronology.
• Calibrate radiocarbon dating or other chronological models for the New Zealand region using the dated tree-ring series.
• Analyze long-term environmental changes by examining growth patterns in the tree-ring parameters over the 250-year span.

Strengths

• Data spans a continuous 250-year period from 220 to 29 BC.
• Sourced from the authoritative NOAA National Centers for Environmental Information Paleoclimatology archive.

Limitations

• Temporal coverage is limited to a specific 250-year window in the past.
• The dataset's last known update was in 1979, potentially indicating outdated metadata or methods.
• Geographic coverage is restricted to a single location in New Zealand, limiting broader regional analysis.
