Argentine Tree-Ring Chronology from 101 to -31 BP

Tree-ring width data from a site in Salta, Argentina, provides a climate proxy record. The time series covers 132 calendar years, from 101 to -31 years before present. This paleoclimatology study is archived and distributed by NOAA's National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual tree-ring width series.
• Calibrate the tree-ring chronology against known climate events using the provided calendar year BP time index.
• Compare this Argentine tree-ring series with other regional proxies to analyze spatial climate patterns.
• Validate climate model simulations for the Southern Hemisphere over the covered 132-year period.

Strengths

• Data spans a specific 132-year period (101 to -31 BP) for climate analysis.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to 132 years, which is short for long-term climate trend analysis.
• Data is geographically limited to a single site (Rio la Sala, Salta) in Argentina.
• The dataset metadata indicates the last update was in 1981, suggesting potential staleness in documentation or methods.
