Rio Kilca Tree Ring Chronology from Neuquen, Argentina

Tree ring width measurements from Neuquen, Argentina, used for paleoclimate reconstruction. The chronology covers a period from 250 to -24 calendar years before present. Data is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past temperature or precipitation anomalies using tree ring width as a proxy.
• Calibrate climate models by comparing the tree ring chronology with instrumental records for the region.
• Analyze growth patterns and extreme events captured in the ring width time series.
• Study long-term ecological responses to climate change in Patagonian forests.

Strengths

• Data spans 274 years of chronological coverage (250 to -24 BP).
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is relatively short for long-term climate trend analysis.
• Geographic scope is limited to a single site in Neuquen, Argentina.
• Data was last updated in 1974, indicating potential staleness in metadata or methods.
