Tree ring width chronology data from Neuquen, Argentina, used for paleoclimate studies. The record covers a 488-year period from 464 to 24 calendar years before present. This archived study was produced by NOAA NCEI's World Data Service for Paleoclimatology and was last updated in 1974.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width chronology series.
- Calibrate climate models for the Southern Hemisphere using the dated annual resolution of the ring width data.
- Study extreme historical climate events in Patagonia by identifying narrow or wide rings within the time-series.
- Perform cross-dating with other regional tree ring chronologies using the shared calendar year BP timeline.
Strengths
- 488-year continuous chronology providing a multi-century climate record.
- Geographically specific data point for a region in Neuquen, Argentina.
Limitations
- Temporal coverage ends 24 years BP, lacking modern or recent data.
- Data last updated in 1974, potentially missing modern methodological refinements.
- Single geographic location limits regional climate inferences.
