Argentine Tree Ring Chronology for Paleoclimate Analysis

233 years of tree ring data from Argentina, covering from 195 to -38 calendar years before present, provide a proxy record for past climate conditions. The dataset is part of the NOAA NCEI World Data Service for Paleoclimatology archive, specifically categorized as a Tree Ring study. Data collection and archiving were conducted by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology as a climate proxy.
• Calibrate climate models by comparing the tree ring time-series data with instrumental records for the overlapping period.
• Analyze the frequency and severity of historical drought events in Patagonia through the tree ring growth parameters.

Strengths

• Covers a 233-year time period (195 to -38 BP)
• Archived and maintained by the authoritative NOAA NCEI World Data Service for Paleoclimatology

Limitations

• Temporal coverage ends at -38 BP, lacking recent centuries for modern climate comparison
• Specific sample size, measurement parameters, and site details are not provided in the available metadata
