Tree Ring Chronology from Lago Rucachoroi Argentina

404 years of tree ring data from Neuquen, Argentina, covering the period from 378 to -26 calendar years before present. This paleoclimatology study is archived by NOAA National Centers for Environmental Information under its World Data Service. The data was last updated in 1976.

Use Cases

• Reconstruct past temperature or precipitation anomalies from the tree ring width chronology.
• Calibrate the chronology against other regional paleoclimate proxies using its annual resolution.
• Analyze long-term climate trends in Patagonia across the 404-year time period coverage.
• Validate climate model simulations for the Southern Hemisphere using the dated proxy record.

Strengths

• 404-year continuous time series from 378 to -26 BP.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Data recency is low, last updated in 1976, potentially missing modern methodological refinements.
• Geographic scope is limited to a single site (Lago Rucachoroi) in Argentina.
