New Zealand Tree Ring Chronology from Upper Hollyford Valley

NOAA/WDS Paleoclimatology archives a tree ring chronology from the Upper Hollyford Valley in New Zealand. The dataset covers the period from 240 to -30 calendar years before present (BP), representing a 270-year record. This study was published by NOAA National Centers for Environmental Information in 1980.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
• Calibrate the chronology against other proxy records using the provided calendar years before present (BP) time index.
• Analyze growth trends and extreme events in the tree ring parameters for the specified 270-year period.

Strengths

• Data is archived by the authoritative NOAA National Centers for Environmental Information (NCEI).
• Covers a specific 270-year time period (240 to -30 BP) for climate reconstruction.

Limitations

• Dataset is temporally stale, last updated in 1980, potentially lacking modern methodological refinements.
• Specific parameters, sample size (row count), and measurement details are not provided in the available metadata.
