Argentine Tree Ring Chronology from 442 to 39 BC

Tree ring width measurements from Cerro Los Pinos, Neuquen, Argentina provide a climate proxy record spanning 481 years. The dataset covers the period from 442 to 39 calendar years before present, offering a window into pre-Incan climate conditions. It is archived by NOAA's World Data Service for Paleoclimatology and was published in 1989.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width parameter as a proxy.
• Calibrate the chronology against other regional paleoclimate records using its 481-year time range from 442 to 39 BP.
• Analyze growth patterns and climate sensitivity for the AUCH species at the specific geographic location of Neuquen, Argentina.

Strengths

• Time series spans 481 calendar years (442 to 39 BP).
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends 39 years before present (1989), providing no data for the modern industrial era.
• The dataset is geographically limited to a single site (Cerro Los Pinos, Neuquen).
• Sample size, replication, and measurement uncertainty are unknown without accessing the full metadata.
