NOAA's Paleoclimatology archive provides a tree ring chronology from the Rio Malenguena site in Tierra del Fuego, Argentina. The data covers a period from 245 to -36 calendar years before present. The dataset was archived by NOAA NCEI's World Data Service for Paleoclimatology in 1986.
Use Cases
- Analyze tree ring width variations to reconstruct past temperature anomalies in Tierra del Fuego.
- Correlate the chronology with other proxy records to validate regional climate models.
- Study the response of local tree species to climatic events during the period from 245 to -36 BP.
Strengths
- Data spans 281 calendar years of coverage.
- Geographic location is precisely specified as Tierra del Fuego, Argentina.
Limitations
