Tree ring width data from the Primeros Pinos de Alumine site in Neuquen, Argentina, provides a paleoclimate record spanning over 800 years. The dataset covers the period from 810 to 24 calendar years before present, archived by NOAA's World Data Service for Paleoclimatology. It was contributed by researcher Holmes and last updated in 1974.
Use Cases
- Reconstruct past temperature and precipitation anomalies in Patagonia by analyzing annual tree ring width variations.
- Calibrate climate models for the Southern Hemisphere using the millennial-scale chronology provided by this record.
- Study the frequency of extreme climatic events, such as droughts, indicated by sequences of narrow tree rings.
- Compare this Argentine chronology with other tree ring series to investigate hemispheric climate teleconnections.
Strengths
- Covers a significant 834-year time period from 810 to 24 BC.
- Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- The data was last updated in 1974, indicating potential staleness and lack of modern methodological revisions.
- Specific sample depth, replication statistics, and measurement details are unknown from the provided metadata.
