Argentine Tree-Ring Chronology from Finca Las Pinchanas (92 to -31 BP)

NOAA/WDS Paleoclimatology archives a tree-ring chronology from Finca Las Pinchanas, Salta, Argentina. The data covers a 124-year period from 92 to -31 calendar years before present. NOAA National Centers for Environmental Information (NCEI) published this study, which was last updated in 1981.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology.
• Calibrate climate models by comparing the chronology with other regional paleoclimate proxies.
• Analyze inter-annual to decadal climate variability in northwestern Argentina over a 124-year period.

Strengths

• Data spans a 124-year period (92 to -31 BP), providing a multi-decadal climate record.
• Archived and maintained by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is relatively short (124 years) for long-term climate trend analysis.
• Data recency is low, with a last update recorded in 1981, potentially limiting modern methodological integration.
