Argentine Tree Ring Chronology From 214 to 41 BC

A 255-year tree-ring chronology from the Pampa del Toro site in Rio Negro, Argentina, covering the period from 214 to 41 calendar years before present. The dataset is part of the NOAA/WDS Paleoclimatology archive and was contributed by researcher Villalba. It is managed by the NOAA National Centers for Environmental Information (NCEI).

Use Cases

• Reconstruct past temperature or precipitation anomalies for Rio Negro, Argentina, using the tree-ring width chronology.
• Calibrate the tree-ring chronology against other regional paleoclimate proxies for multi-proxy climate reconstruction.
• Analyze the growth response and climate sensitivity of the AUCH species (Austrocedrus chilensis) during the covered period.

Strengths

• Covers a specific 255-year period (214 to 41 BP) useful for focused climate studies.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to a single, ancient period and lacks modern context.
• Data is from a single geographic site (Rio Negro, Argentina), limiting regional generalization.
• The dataset was last updated in 1991, indicating potential staleness in metadata or curation.
