Central Andes Tree Ring Width Chronology for Paleoclimate Reconstruction

Tree ring width measurements from the Central Andes region of Argentina, compiled by NOAA NCEI. The chronology covers a period from 81 to -44 calendar years before present. This dataset is part of the PAGES LOTRED-SA paleoclimate reconstruction project.

Use Cases

• Reconstruct historical temperature or precipitation anomalies in the Central Andes using the tree ring width chronology.
• Calibrate the chronology against other proxy records using its calendar year before present (BP) time index.
• Analyze climate forcing events by examining patterns in the ring width time-series data.
• Validate the PAGES LOTRED-SA regional climate reconstruction with this specific tree ring dataset.

Strengths

• Time-series data spans 125 calendar years (from 81 to -44 BP).
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Part of the standardized PAGES LOTRED-SA regional reconstruction project.

Limitations

• Dataset metadata indicates a last update in 1994, suggesting potential staleness.
• Specific sample size, geographic precision, and measurement parameters are not detailed in the provided description.
• Coverage is limited to a single region in Argentina.
