Argentine Tree Ring Chronology From 558 to -26 BP

Neuquen, Argentina tree ring data spans 584 calendar years, from 558 to -26 years before present. The dataset was archived by NOAA National Centers for Environmental Information under its Paleoclimatology program. It was last updated in the NOAA system in 1976.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
• Calibrate climate models by comparing the tree ring proxy data with instrumental records for the region.
• Analyze the frequency of extreme climatic events encoded in the tree ring series.
• Study ecological responses to climate change over a multi-century timeframe using the dated tree ring sequences.

Strengths

• Covers a 584-year timeframe for long-term climate analysis.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends 26 years before present, lacking very recent data.
• Data is geographically limited to a single site (Lago Rucachoroi, Neuquen, Argentina).
• The last recorded update was in 1976, indicating potential staleness in metadata or access methods.
