Glaciar Frias Tree Ring Width Data For South American Climate Reconstruction

183 calendar years of tree-ring width data from Argentina, covering the period from 148 to -35 years before present. The dataset is part of the NOAA/WDS Paleoclimatology archive and the PAGES LOTRED-SA initiative, produced by the NOAA National Centers for Environmental Information. It was archived in 1985.

Use Cases

• Reconstruct historical temperature or precipitation anomalies in Patagonia using the tree-ring width time-series.
• Analyze climate periodicity and extreme events over 183 years by examining the annual resolution ring width data.
• Calibrate the tree-ring width chronology against other paleoclimate proxies for the LOTRED-SA regional network.
• Study the response of high-latitude Southern Hemisphere forests to past climate forcing using the dated series.

Strengths

• Covers a continuous 183-year time period suitable for trend analysis.
• Provides annual-resolution proxy data for a region with sparse historical climate records.
• Part of the curated PAGES LOTRED-SA version, indicating peer-reviewed integration.

Limitations

• The temporal coverage ends at -35 BP (approx. 1985 CE), offering no recent data for modern comparison.
• Limited to a single geographic location (Glaciar Frias, Argentina), reducing regional representativeness.
• The dataset's age suggests metadata and formats may not align with modern standards.
