171-year tree ring chronology from Rio Negro, Argentina, covering 130 to -41 calendar years before present. The dataset contains parameters for dendroclimatological analysis, archived by NOAA NCEI's World Data Service for Paleoclimatology. Data was published in 1991.
Use Cases
- Reconstruct past temperature or precipitation using tree ring width parameters as a climate proxy.
- Calibrate climate models by comparing the tree ring chronology with known historical climate periods.
- Analyze climate variability in Patagonia by examining year-to-year changes in the ring data over the 171-year period.
- Study extreme climate events, such as droughts, through anomalies in the tree ring growth parameters.
Strengths
- Covers a 171-year period (130 to -41 BP), providing a multi-century climate record.
- Sourced from NOAA NCEI's authoritative World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, last updated in 1991, and may not reflect more recent scientific methods.
- Geographic coverage is limited to a single site (Rio Negro, Argentina), limiting regional generalization.
- Specific parameters, sample depth, and measurement details are unknown without accessing metadata.
