New Zealand Snowslide Stream Tree Ring Chronology

NOAA's World Data Service for Paleoclimatology archives this tree ring chronology from the Snowslide Stream site in New Zealand. The data provides a proxy climate record covering a period from 190 to -29 calendar years before present. The dataset was contributed by author Norton and published by NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies for New Zealand using the tree-ring width chronology as a proxy.
• Calibrate the tree-ring chronology against known climate events within the 219-year time span covered by the data.
• Analyze growth trends and potential climate signals embedded in the Snowslide Stream site's ring-width series.

Strengths

• Data spans a continuous 219-year period (190 to -29 BP).
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
• Focuses on a specific geographic location (New Zealand) for regional climate analysis.

Limitations

• The dataset's last update was in 1979, indicating it is a static, historical archive.
• The specific sample depth, measurement statistics, and climate parameter correlations are not detailed in the provided metadata.
• Geographic coverage is limited to a single site (Snowslide Stream).
