Central Andes Tree Ring Width Composite for Paleoclimate Reconstruction

146-year composite of tree ring width data from the Central Andes, spanning from 105 to -41 calendar years before present. The dataset is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1991. It provides parameters for paleoclimate studies in Argentina.

Use Cases

• Reconstructing historical precipitation or temperature anomalies in the Central Andes using the tree ring width time-series.
• Calibrating regional climate proxies by analyzing the variance and trends within the 146-year composite record.
• Studying inter-annual climate variability and extreme events in pre-Incan periods through the high-resolution ring width data.

Strengths

• Covers a 146-year time period (105 to -41 BP), providing a multi-decadal climate record.
• Archived and maintained by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last update recorded in 1991.
• Specific sample size, geographic precision, and measurement methodologies are not detailed in the provided metadata.
