New Zealand Tree Ring Chronology from Lake Eyles

NOAA/WDS Paleoclimatology archives a tree ring chronology from the Lake Eyles site in New Zealand. The data covers 304 years, from 274 to -30 calendar years before present (BP), and is maintained by NOAA's National Centers for Environmental Information. This record was archived in 1980.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing annual tree-ring width variations.
• Calibrate radiocarbon dating curves using the precisely dated tree-ring chronology.
• Study extreme climate events in New Zealand's history by identifying marker years in the ring series.
• Compare Southern Hemisphere climate proxies by aligning the Lake Eyles chronology with other regional records.

Strengths

• Data spans a continuous 304-year period (274 to -30 BP).
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
• Provides a geographically specific record for New Zealand.

Limitations

• Temporal coverage is relatively short for long-term climate trend analysis.
• Data is geographically limited to a single site (Lake Eyles).
• The dataset was last updated in 1980, potentially lacking modern reanalysis.
