Argentine Tree Ring Chronology from Paso del Viento

Tree ring width data from Neuquen, Argentina provides a climate proxy record spanning 312 years from 271 to -41 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information's World Data Service for Paleoclimatology. This specific chronology, identified as ARGE086, was contributed by researcher Villalba and last updated in 1991.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual tree-ring width series.
• Calibrate the chronology against other regional proxies using the documented calendar year timestamps.
• Study climate variability in the Patagonian Andes during the period covered by the 312-year record.
• Assess growth trends and potential environmental stressors for the tree species at the documented Neuquen location.

Strengths

• Chronology spans a continuous 312-year period from 271 to -41 BP.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Provides a precisely dated annual resolution proxy for climate reconstruction.

Limitations

• Data was last updated in 1991, representing a potentially outdated compilation or methodology.
• Geographic coverage is limited to a single site (Paso del Viento, Neuquen, Argentina).
• The raw measurement data, metadata details, and sample depth are not described in the provided input.
