Argentine Tree Ring Chronology from Rio Negro Province

NOAA's World Data Service for Paleoclimatology archives this tree ring chronology from the Paso de las Nubes 3 site in Rio Negro, Argentina. The data provides a paleoclimate record spanning 273 years, from 232 to -41 calendar years before present. It was contributed by researcher Villalba and published through NOAA NCEI.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the annual tree-ring width series.
• Calibrate climate models by comparing the chronology's growth patterns with known historical climate events.
• Analyze long-term climate trends in Patagonia by examining the multi-century tree-ring index.
• Perform cross-dating with other Southern Hemisphere tree-ring chronologies using the year-by-year growth measurements.

Strengths

• Covers a 273-year time period (232 to -41 BP).
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
• Includes precise geographic location data for Rio Negro, Argentina.
