Argentine Tree Ring Chronology from Paso de las Nubes 2

NOAA/WDS Paleoclimatology archives a tree ring chronology from the Paso de las Nubes 2 site in Rio Negro, Argentina. The dataset provides parameters for climate reconstruction, covering a period from 100 to -41 calendar years before present. It was published by NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology as a proxy.
• Calibrate climate models by comparing the tree ring time-series data with instrumental records for the region.
• Analyze climate extremes and variability over a 141-year period from the tree ring parameters.
• Study ecological responses to historical climate events in the Rio Negro, Argentina region using the dated tree ring series.

Strengths

• Covers a specific 141-year period (100 to -41 BP) for climate analysis.
• Sourced from the authoritative NOAA National Centers for Environmental Information (NCEI).
• Part of the World Data Service for Paleoclimatology, ensuring archival standards.

Limitations

• Temporal coverage is limited to a specific 141-year snapshot, not a continuous long record.
• Geographic scope is restricted to a single site (Paso de las Nubes 2, Rio Negro).
• Data was last updated in 1991, potentially lacking modern reanalysis or newer methodologies.
