Argentine Tree-Ring Chronology from 383 to -42 BP

NOAA/WDS Paleoclimatology archives a tree-ring chronology from the Nahuel-Pan site in Neuquen, Argentina. The dataset provides annual-resolution climate proxy data covering a 425-year period from 383 to -42 calendar years before present. It was published by researcher Villalba and archived by NOAA National Centers for Environmental Information in 1992.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a proxy.
• Analyze climate periodicity and extreme events over a 425-year span using the annual-resolution time series.
• Calibrate regional climate models by comparing the tree-ring proxy record from Neuquen, Argentina with instrumental data.
• Study ecological responses to past climate change through the annual growth variations captured in the chronology.

Strengths

• Covers a continuous 425-year period from 383 to -42 BP.
• Provides annual-resolution proxy data for high-precision climate analysis.
• Archived and standardized by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last documented update was in 1992, indicating potential staleness.
• Specific sample depth, replication statistics, and measurement parameters are not detailed in the provided metadata.
• Geographic coverage is limited to a single site (Nahuel-Pan) in Argentina.
