Argentine Tree Ring Chronology for Climate Reconstruction

Tree ring width measurements from El Arrasayal, Argentina, provide a 219-year chronology for paleoclimate analysis. The dataset covers the period from 184 to -35 calendar years before present, indicating it includes years both before and after the 1950 baseline. It is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1985.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width time series.
• Calibrate climate models using the precisely dated 219-year chronology from this site.
• Perform cross-dating with other regional tree ring chronologies using the shared time period coverage.
• Study long-term climate trends in Argentina by examining the ring width parameter over two centuries.

Strengths

• Covers a 219-year time period (184 to -35 BP).
• Part of the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, last updated in 1985.
• Geographic coverage is limited to a single site in Argentina.
• Specific sample depth, measurement statistics, and raw measurement data are not described.
