Argentine Tree Ring Chronology from Cuyin Manzano

Neuquen, Argentina tree ring data covering 431 years, from 407 to -24 calendar years before present. The dataset is part of the NOAA NCEI World Data Service for Paleoclimatology, archived under the Tree Ring study type. The data was last updated in 1974.

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 other paleoclimate records for the Southern Hemisphere.
• Analyze long-term climate trends in Patagonia by examining the year-by-year tree ring measurements.
• Study the response of native tree species to historical climate events recorded in the ring parameters.

Strengths

• Covers a 431-year time period (407 to -24 BP), providing a multi-century climate record.
• Geographically specific data from Neuquen, Argentina, sourced from the authoritative NOAA NCEI WDS for Paleoclimatology.

Limitations

• Temporal coverage ends at -24 BP (approximately 1974 CE), with no updates for nearly 50 years, limiting modern relevance.
• Unknown sample size and specific measurement parameters (e.g., ring width, density) without examining full metadata.
• Data is localized to a single site in Argentina, which may not be representative of broader regional climate.
