NOAA/WDS Paleoclimatology archives a tree-ring chronology from a krummholz site in Río Negro, Argentina. The dataset provides parameters for climate reconstruction, covering a period from 72 to -41 calendar years before present. It is maintained by the NOAA National Centers for Environmental Information.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology.
- Calibrate climate models by comparing the proxy time-series data with instrumental records.
- Analyze extreme climate events in Patagonia by identifying narrow or wide ring sequences in the chronology.
- Study ecological responses to climate change by examining growth parameters from the krummholz environment.
Strengths
- Data spans 113 calendar years, providing a multi-decadal climate record.
- Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Sample size and replication statistics for the tree-ring series are unknown.
- Temporal coverage is relatively short for long-term climate trend analysis.
- Data was last updated in 1991, indicating potential staleness.
