Tree ring width measurements from Rio Negro, Argentina, provide a 290-year climate proxy record. The data was archived by the NOAA National Centers for Environmental Information's World Data Service for Paleoclimatology. This study was last updated in 1991.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree ring width parameter as a proxy.
- Calibrate climate models by comparing the tree ring chronology against other paleoclimate records for the period 249-41 BC.
- Analyze growth patterns in the 'NOPU' species (likely Nothofagus pumilio) to understand ecological responses to ancient climate events.
Strengths
- Covers a continuous 290-year period from 249 to 41 BC.
- Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, with a last update recorded in 1991.
- Limited geographic scope to a single location in Rio Negro, Argentina.
- Specific sample depth, measurement methods, and potential uncertainties are not detailed in the provided metadata.
