Argentine Tree Ring Chronology from Cerro La Hormiga (442 to -39 BP)

A tree-ring chronology from Neuquen, Argentina, covering the period from 442 to -39 calendar years before present (BP). The dataset was produced by the NOAA National Centers for Environmental Information's World Data Service for Paleoclimatology. It was last updated in the archive in 1989.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width series as a climate proxy.
• Calibrate the tree-ring chronology against known historical climate events within the 481-year time span.
• Analyze long-term climate trends in the Neuquen region by examining the variance in the ring-width parameter over centuries.

Strengths

• Covers a 481-year time period (442 to -39 BP).
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last known update in 1989.
• Geographic scope is limited to a single site (Cerro La Hormiga Estancia Collun-co) in Argentina.
