Vilches Tree Ring Width Chronology For South American Climate Reconstruction

Tree ring width measurements from Chile provide a 116-year chronology from 70 to -46 calendar years before present. The NOAA National Centers for Environmental Information archives this paleoclimatology study for reconstructing past climate conditions. Data was published and last updated in 1996.

Use Cases

• Calibrate climate models by correlating tree ring width variations with known historical climate events in the time series.
• Analyze long-term climate trends in South America using the 116-year proxy record from Chile.
• Reconstruct historical temperature or precipitation anomalies from the Vilches site's geospatial tree ring data.

Strengths

• Covers a 116-year time period (70 to -46 calendar years BP) for climate analysis.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last update recorded in 1996.
• Geographic coverage is limited to a single site in Chile, limiting regional generalizations.
• Unknown sample size and replication depth for the tree ring chronology.
