NOAA/WDS Paleoclimatology archives a tree ring chronology from the Castaño Overo 2 site in Rio Negro, Argentina. The data covers a period from 60 to -41 calendar years before present, used for climate reconstruction. It is maintained by the NOAA National Centers for Environmental Information.
Use Cases
- Reconstruct past temperature or precipitation using the tree ring width chronology from the Castaño Overo 2 site.
- Calibrate climate models by comparing the time-series data against other proxy records for the period 60 to -41 BP.
- Analyze climate extremes in the Rio Negro region of Argentina using the annual resolution of the tree ring record.
- Study the response of tree growth to environmental factors by examining the ring width parameter over a 101-year span.
Strengths
- Data covers a specific 101-year time period (60 to -41 BP).
- Sourced from the authoritative NOAA National Centers for Environmental Information (NCEI).
- Provides annual-resolution proxy data for climate reconstruction.
Limitations
- Temporal coverage is limited to a single century, which is short for some paleoclimate studies.
- Geographic scope is restricted to a single site (Castaño Overo 2, Rio Negro, Argentina).
- Data was last updated in 1991, indicating potential staleness in metadata or availability.
