341-year tree-ring chronology from Neuquen, Argentina, covering the period from 300 to 41 BC. The dataset was archived by NOAA's World Data Service for Paleoclimatology and is associated with a study authored by Villalba. This paleoclimatology record was last updated in 1991.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree-ring width series.
• Analyze long-term climate trends and variability in the Neuquen region of Argentina across the 341-year period.
• Calibrate and validate climate models for the Southern Hemisphere using this proxy record from 300-41 BC.
• Perform cross-dating of other paleoclimate archives from South America using this established tree-ring chronology.

Strengths

• 341-year continuous temporal coverage from 300 to 41 BC.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
