Argentine Tree Ring Chronology from 250 to 42 BCE

Tree ring width data from Chubut, Argentina, covers a 292-year period from 250 to 42 BCE. The dataset is part of the NOAA NCEI World Data Service for Paleoclimatology archive, contributed by the author Villalba. It was last updated in the NOAA system in 1992.

Use Cases

• Reconstruct past temperature or precipitation anomalies in Patagonia using the tree ring width chronology.
• Calibrate the tree ring proxy record against other paleoclimate archives for the specified 292-year period.
• Analyze the frequency of narrow or wide tree ring years to identify periods of climatic stress or favorable growth conditions.

Strengths

• Covers a continuous 292-year period for climate analysis.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last known update was in 1992, indicating potential staleness.
• The specific sample depth (number of tree cores) and measurement statistics are unknown.
