Argentine Tree Ring Chronology from Lago Moquehue

NOAA/WDS Paleoclimatology archives a tree-ring chronology from Lago Moquehue in Neuquen, Argentina. The dataset provides parameters for climate reconstruction, covering the period from 349 to -24 calendar years before present (BP). It is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width index as a proxy.
• Calibrate climate models by comparing the chronology's time-series data with instrumental records.
• Analyze extreme climate events or long-term trends within the 373-year temporal coverage.
• Study ecological responses to historical climate shifts in the Patagonian region of Argentina.

Strengths

• Time-series data spans 373 calendar years (349 to -24 BP).
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Dataset metadata indicates a last update in 1974, suggesting potential staleness.
• Specific sample depth, measurement parameters, and replication statistics are not provided in the input.
