Argentine Tree Ring Chronology from Cerro Los Leones (411 to -41 BP)

Tree ring parameters from Neuquen, Argentina provide a 452-year chronology from 411 to -41 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. This paleoclimate study was last updated in 1991.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology.
• Calibrate the tree-ring proxy record against other paleoclimate datasets for the Neuquen region.
• Analyze the growth response and climate sensitivity captured in the tree-ring parameters over a 452-year period.

Strengths

• 452-year temporal coverage from 411 to -41 BP
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology

Limitations

• Data is temporally stale, last updated in 1991
• Sample size, geographic resolution, and specific measured parameters are not detailed in the provided metadata
