Tree ring data from a Santa Cruz, Argentina site provides a 278-year chronology from 244 to -34 calendar years before present. The NOAA National Centers for Environmental Information archives this paleoclimatology study under its World Data Service. The data was last updated in the repository in 1984.
Use Cases
- Calibrating regional climate models using the 278-year tree-ring width chronology.
- Analyzing growth anomaly patterns within the chronology to identify past drought events.
- Cross-dating this ITRDB ARGE063 series with other South American chronologies to validate temporal coverage.
- Reconstructing past temperature or precipitation indices for Argentina from the tree-ring parameter data.
Strengths
- 278-year continuous chronology from 244 to -34 BP provides a multi-century climate record.
- Data is archived and curated by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- The dataset's last known update was in 1984, indicating potential methodological staleness.
- The specific tree-ring parameters (e.g., width, density) and sample depth are not detailed in the provided metadata.
- Geographic coverage is limited to a single site in Santa Cruz, Argentina.
