New Zealand Tree Ring Chronology from Waihora Stream

Tree ring width chronology data from the Waihora Stream site in New Zealand, used as a proxy for past climate conditions. The dataset covers a period from 400 to -36 calendar years before present, indicating it includes years after the 1950 reference date. It was produced by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology and was last updated in 1986.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual tree_ring_width chronology.
• Calibrate climate models for the New Zealand region using the 436-year proxy record ending around 1986.
• Study the frequency of extreme climate events in the pre-instrumental era through anomalies in the ring_width time-series.
• Compare this Southern Hemisphere tree_ring record with other global paleoclimate proxies for hemispheric teleconnections.

Strengths

• Provides a 436-year continuous proxy climate record for New Zealand.
• Data is archived and curated by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1986, making it temporally stale for recent climate studies.
• Specific parameters and measurement details are only available in the metadata, not in the provided description.
