Central Andes Tree Ring Width Chronology from 85 to -48 BP

Central Andes composite tree ring width data provides a paleoclimate record for Argentina. The dataset covers 133 years from 85 to -48 calendar years before present. It was archived by NOAA NCEI's World Data Service for Paleoclimatology and last updated in 1998.

Use Cases

• Reconstruct historical climate variables like temperature or precipitation from tree ring width time-series.
• Calibrate climate models by comparing the 133-year tree ring chronology with simulated past climates.
• Analyze climate anomalies and trends in the Central Andes region during the period from 85 to -48 BP.

Strengths

• Covers a specific 133-year time period (85 to -48 BP).
• Data is part of the authoritative PAGES LOTRED-SA compilation.

Limitations

• Temporal coverage is limited to 133 years, a relatively short period for some paleoclimate studies.
• Data is geographically focused on a single region (Argentina, Central Andes), limiting broader spatial analysis.
• The dataset was last updated in 1998, indicating potential staleness in metadata or documentation.
