Tree ring data spanning 409 years from 375 to -34 calendar years before present, providing paleoclimate parameters for Argentina. The dataset is archived by NOAA's National Centers for Environmental Information under its World Data Service for Paleoclimatology. The data was last updated in 1984.
Use Cases
- Analyzing tree ring width variations to reconstruct past temperature anomalies over the 409-year period.
- Correlating isotopic or density parameters from tree rings with historical drought events in Argentina.
- Calibrating radiocarbon dating models using the dated tree ring sequences from the Lago Escondido site.
- Studying long-term climate variability by comparing the tree ring parameters with other proxy records from the region.
Strengths
- Data covers a 409-year time period from 375 to -34 calendar years BP.
- Provided by NOAA NCEI, an authoritative source for paleoclimate archives.
Limitations
- Data is temporally stale, last updated in 1984, potentially lacking modern methodological refinements.
- Specific parameters, sample size, and measurement details are unknown from the provided description.
