A 177-year tree-ring chronology from Rio Negro, Argentina, covering the period from 136 to -41 calendar years before present. The dataset is part of the NOAA/WDS Paleoclimatology archive, contributed by Villalba and archived by NOAA NCEI. The data were last updated in the archive in 1991.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a climate proxy.
- Calibrate the chronology against other regional paleoclimate records using its specific temporal coverage from 136 to -41 BP.
- Analyze climate signal strength and persistence in Patagonian forests using the site-specific parameters from the Rio Negro location.
Strengths
- Covers a specific 177-year period (136 to -41 BP) for climate analysis.
- Archived by the authoritative NOAA National Centers for Environmental Information (NCEI).
- Includes geospatial location data for Rio Negro, Argentina.
