New Zealand Tree Ring Chronology from Aston Creek

230 to -29 calendar years before present of tree ring width measurements from Aston Creek, New Zealand. The dataset provides paleoclimatic proxy data for reconstructing past environmental conditions. It is archived by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width time-series as a proxy.
• Calibrate climate models by comparing the tree ring chronology with other paleoclimate records for the region.
• Analyze growth trends and extreme climatic events recorded in the ring width parameter over the 259-year period.

Strengths

• Covers a 259-year time period from 230 to -29 calendar years BP.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last known update was in 1979, indicating potential staleness.
• Sample size, geographic precision, and specific measurement parameters are not detailed in the provided metadata.
