Tree Ring Chronology from El Mirador, Argentina (315 to -41 BP)

A tree ring chronology from the El Mirador site in Neuquen, Argentina, covering the period from 315 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. The data was last updated in the NOAA system in 1991.

Use Cases

• Reconstruct past temperature or precipitation anomalies for the Neuquen region using the annual tree ring width series.
• Calibrate regional climate models by comparing the tree ring chronology with other proxy records from a similar time period.
• Analyze the frequency and severity of historical drought events in Patagonia through the examination of narrow ring sequences in the chronology.
• Establish a dated timeline for archaeological or geological events in the Traful area using the absolute dating provided by the tree ring series.

Strengths

• Time series spans 356 years (315 to -41 BP), providing a multi-century climate record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last known update was in 1991, indicating it is a static archive and may not reflect newer analyses.
• Specific parameters (e.g., ring width, density) and measurement details are not listed in the provided description, requiring metadata review.
