Argentine Tree Ring Chronology from 704 to 24 BCE

A tree-ring chronology from Neuquen, Argentina, covering 728 calendar years from 704 to 24 years before present. The dataset was archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. The original study was published in 1974.

Use Cases

• Reconstruct past temperature or precipitation anomalies for the Neuquen region using the annual-resolution tree-ring width series.
• Calibrate radiocarbon dating or synchronize regional chronologies by matching patterns in the ring-width index data.
• Analyze climate forcing on forest growth by correlating the tree-ring parameter with known volcanic or solar events within the 704-24 BCE period.

Strengths

• Covers a continuous 728-year period, providing a long-term climate proxy.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset is temporally stale, with a last update date of 1974.
• The specific measured parameters (e.g., ring width, density) and sample depth are not detailed in the provided metadata.
