Argentine Tree Ring Chronology for Climate Reconstruction

183-year tree ring chronology from the Castaño Overo 3 site in Rio Negro, Argentina, covering the period from 142 to -41 calendar years before present. The dataset is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1991. It provides parameters for dendroclimatological analysis to reconstruct past environmental conditions.

Use Cases

• Reconstructing past temperature or precipitation anomalies using the tree ring width chronology.
• Calibrating climate models by comparing the proxy record from Rio Negro, Argentina with instrumental data.
• Analyzing long-term climate trends in Patagonia through the 183-year time series.
• Studying the response of tree growth to environmental stressors documented in the ring parameters.

Strengths

• 183-year temporal coverage providing a multi-century climate proxy.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at -41 BP (1991 CE), lacking recent decades.
• Geographic scope is limited to a single site (Rio Negro, Argentina).
• Data was last updated in 1991, indicating potential staleness in metadata or methods.
