Argentine Rio Negro Tree Ring Chronology from 217 to -41 BP

258-year tree-ring chronology from Pilcaniyeu, Rio Negro, Argentina, provides data for paleoclimate reconstruction. The dataset, archived by NOAA NCEI's World Data Service for Paleoclimatology, is a contribution from researcher Villalba. It was last updated in the repository in 1991.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a climate proxy.
• Calibrate the chronology against known climate events within the 217 to -41 BP time period for Southern Hemisphere climate studies.
• Analyze growth trends and extreme years in the Pilcaniyeu AUCH tree-ring series to identify past environmental stressors.
• Compare this Rio Negro, Argentina chronology with other ITRDB series (ARGE081) for regional climate signal analysis.

Strengths

• Covers a 258-year time period (217 to -41 BP) for climate analysis.
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) under NOAA NCEI.

Limitations

• Temporal coverage ends at 41 BC (calendar years before present), lacking recent centuries.
• Data last updated in 1991, potentially missing subsequent methodological revisions or metadata enhancements.
• Specific sample depth, measurement parameters, and site details are not provided in the basic description.
